Project Management (PM) does not deal with "Business as Usual", PM deals with projects or with tasks that have a beginning, middle and end, and evolve over the course of time until the project is handed over to a client.
PMN balance Budget, Time, and Money and Staff in the phases of Planning/Initation, overseeing Execution and Monitoring, Troubleshooting and Closing.
PMN execute in different ways under Information Technology, Biotech, or Construction. Generally PMN deal with Scheduling, Tracking, Budget Control, Risk Management, Strategizing, Quality Management, Workflow Control, involving Resource Allocation, Human Resource Management, Material Resource Management, and Tme Mangement.

Value Management
This post is about learning the basic fundaments about calculating value, reducing losses, and understanding the constraints related to projec management. The list will not be exhaustive, however, with your help this list can be refined and sharpened to focus on the more salient or pertinent calculations regarding this matter. Most projects can be manages with simple spreadsheets but Engineering Projects involve short term and long term predictions on the impact of expenditures on the overall budget and these considerations are communicated frequently to investors and stakeholders. The results of these calculations have imminent effects on the final physical structure and often lead to drastic project overhaul or expansions.
Planned value (PV): The approved budget for the work scheduled to be completed by a specified date; also referred to as the budgeted cost of work scheduled (BCWS). The total PV of a task is equal to the task’s budget at completion (BAC)— the total amount budgeted for the task.
Earned value (EV): The approved budget for the work actually completed by the specified date; also referred to as the budgeted cost of work performed (BCWP).
Actual cost (AC): The costs actually incurred for the work completed by the specified date; also referred to as the actual cost of work performed(ACWP).
Schedule variance (SV): The difference between the amounts budgeted for the work you actually did and for the work you planned to do. The SV shows whether and by how much your work is ahead of or behind your approved schedule.Cost variance (CV): The difference between the amount budgeted and the amount actually spent for the work performed. The CV shows whether and by how much you’re under or over your approved budget.
Schedule performance index (SPI): The ratio of the approved budget for the work performed to the approved budget for the work planned. The SPI reflects the relative amount the project is ahead of or behind schedule, sometimes referred to as the project’s schedule efficiency. You can use the SPI to date to project the schedule performance for the remainder of the task.
Cost performance index (CPI): The ratio of the approved budget for work performed to what you actually spent for the work. The CPI reflects the relative value of work done compared to the amount paid for it, sometimes referred to as the project’s cost efficiency. You can use the CPI to date to project the cost performance for the remainder of the task.
Schedule and cost variances and performance indicators are defined mathematically as follows:
Schedule variance (SV) = Earned value (EV) – Planned value (PV)
Cost variance (CV) = Earned value (EV) – Actual cost (AC)
Schedule performance index (SPI) = Earned value (EV) / Planned value (PV)
Cost performance index (CPI) = Earned value (EV) / Actual cost (AC)The final step when assessing task performance to date is to update what you expect your total expenditures will be upon task completion. Specifically, you want to determine the following:
Estimate at completion (EAC): Your estimate today of the total cost of the task
Estimate to complete (ETC): Your estimate of the amount of funds required to complete all work still remaining to be done on the task
PM: ISO3100 RISK MANAGEMENT Risks are about events that, when triggered, cause problems or benefits. Any event that may endanger achieving an objective partly or completely is identified as risk.
Identification: Once risks have been identified, they must then be assessed as to their potential severity of impact (generally a negative impact, such as damage or loss) and to the probability of occurrence.
Assessment: Once risks have assessed, all techniques to manage the risk fall into one or more of these four major categories:
Implementation and Review: Evaluate whether the previously selected security controls are still applicable and effective
Prioritizing the risk management processes too highly could keep an organization from ever completing a project or even getting started.
Risk Analysis Tools:
Fault tree analysis (FTA)
Failure mode and effect analysis (FMEA)
Hazard and operability study (HAZOP)
Risk traceability analysis

Drug Manufacturing Quality Documentation: Managing a Drug Manufacturing Site requires precise control over all steps that impact the Identity, Purity, Efficacy, and Quality of the product. The high level of precision requires that manufacturing tasks are well understood by personnel and these tasks are not limited to steps making the drug product. Control requires ALL areas to provide the highest standards of as required by local and international standardizing and regulatory bodies.
Have you covered all aspects of the working site? Are you missing a an area? Would you imagine working in areas where tasks were not defined? Documentation needs to describe the areas, processes, machines, units as well as steps, calculations and precautions.
There are many more areas that require precise documentation to provide the rigor and control required to produce a high quality chemical product.
In order to produce and control such documents facilities have document management systems that provide easy access to employees. Employees become familiar with the tasks before executing them and with these documents employees are Trained-and-Tested to provide a level of proficiency prior to execution. These documents are "Living Documents", what this means is that once drafted the documents are not destroyed. Instead they go through a lifetime of changes and these changes however minor are docmented and tracked within the document so people reading the document can see the changes to the document through revisions.
Changes do not become effective until 75-85% of all employees have been trained on the changes. So after rigorous control it is expeced that changes howere impactful or minor are taken into account by all employees driving continuous improvement.

selected sterilization doses of 25 kGy and 15 kGy. The method for 25 kGy is applicable to products having an average bioburden less than or equal to 1,000 CFUs (colony forming units) per device. The method for 15 kGy is applicable to products having an average bioburden less than or equal to 1.5 CFUs per device. VDmax Method: Justification for a sterilising dose of 25 kGy or 15 kGy Bellow is an example of the procedure for the VDmax 25 method on multiple production batches 1- Obtain product samples The product samples must be representative of routinely sterilised products. 2- Determine the average microbial load of 3 batches of 10 pieces 3- According to the table of ISO11137-2, determine the verification dose 4- Conduct verification dose experiments; irradiate 10 products at the verification dose and perform a sterility test on each of the products 5- Interpret the results: Accept the 25 kGy sterilisation dose if 0 or 1 of the 10 pieces is positive. Conduct verification dose confirmation experiments if 2 are positive. Do not accept the verification if there are more than 2 positives 40 products are required for this method. This method is only viable for validating sterilising doses of 15 or 25 kGy. |
Method 1 | 1- Select the sterility assurance level (SAL) and select 10 product samples from 3 independent production batches (or 30 samples) 2- Determine the average microbial load of the 3 batches of 10 items (method based on ISO 11737-1) 3- Obtain the verification dose (referring to table 5 of ISO11137-2) 4- Conduct verification dose experiments on 100 irradiated pieces (method based on ISO 11737- 2) 5- Interpret the results 6- Establish the sterilisation dose based on the results (maximum of 2 positives out of 100 pieces) 130 products are therefore required for this method. The advantage of this method is that it enables any sterilising dose to be validated. |
Method 2A Method 2B |
1- Select the sterility assurance level (SAL) and obtain samples of the product (at least 280 samples for 2 independent production batches) The product samples must be representative of the products routinely sterilised. 2- Conduct the incremental dose experiments; irradiate 20 pieces at incremental doses of 2 kGy beginning with the 2 kGy dose and using at least 9 values. This is to be done for each of the 3 batches involved. Perform a sterility test on each of the products. 3- Conduct verification dose experiments; irradiate 100 pieces at the verification dose and perform a sterility test on each of the products 4- Examine the results 5- Establish the sterilising dose based on the results |
Performance Qualification (PQ)
Product PQ: carried out under the supervision of the product manufacturer. This determines compliance of the sterilization process on the product.
1) Dose Mapping: The first step of the validation is to verify that every product in the sterilization container receives a dose complying with the specifications (for example 25-40 kGy). As the dose received by the products can depend of the density of the products and their position in the sterilization container, before performing the dose mapping validation, the product loaded patter shall be established. With this product loaded pattern, dosimeters will be placed to measure the dose received by the products at different points of the sterilization container.
2) Validation of the sterilising dose: This part of the product PQ makes it possible to validate the minimum irradiation dose required to sterilise the product (i.e. to guarantee a sterility assurance level (SAL) of 10-6). 3) Validation of the maximum dose: This part of the validation procedure verifies by means of various kinds of tests that product characteristics are not degraded by irradiation, even at the maximum dose.

This parameter tells you what is the "process spread" assuming that manufacturing is normal. Cp shows whether the distribution can potentially fit inside the specification A high Cp tells you that variation in output is low around process specification. Uses Subgroup Variation. |
||||||||||||||||||
Cpk | Cpk = Min(CpU,CpL) Ability to produce outcome within specification Desribes how mean is centered within Specification. Shows whether the overall average is centrally located. Cpk =2 means your width can grow 2 times before going OOS Cpk can never exceed Cp. Cp can be seen as the potential Cpk if the overall average is centrally set. If Cp is 1.20 and Cpk is 0.69. This shows that the distribution can potentially fit within the specification. However, the overall average is currently off center. The Cpk value does not state whether the overall average is offset on the upper or lower side. Cpk=1.0), a process will produce approximately 99.73% good product or .27% bad product. At Cpk = 1.33.the process will manufacture approximately 99.9937% good product or .0063% bad product. |

Hypothesis Testing Null Hypothesis |
Statement of rejection adopted to commence a statistical analysis. Null hypotheses are not inferred directly.The Null hypothesis is rejected by testing the validity of the opposite statement.
http://support.minitab.com/en-us/minitab/17/topic-library/basic-statistics-and-graphs/hypothesis-tests/basics/type-i-and-type-ii-error/ |
||||||||||||||||||
P Value | Small p-value (typically ≤ 0.05) indicates STRONG evidence AGAINST the NULL hypothesis, so you reject the null hypothesis. Large p-value (> 0.05) indicates WEAK evidence AGAINST the NULL hypothesis, so you fail to reject the null hypothesis p-values very close to the cutoff (0.05) are considered to be marginal (could go either way). |
||||||||||||||||||
Error Tipo 1 | False Positive: Incorrect Rejection of null hypothesis. The probability of making a type I error is α, which is the level of significance you set for your hypothesis test. An α of 0.05 indicates that you are willing to accept a 5% chance that you are wrong when you reject the null hypothesis. For a fixed sample size, the probability of making a Type II error is inversely related to the probability of making a Type I error. Thus, in order to achieve a desirable power for a fixed level of significance, the sample size will generally need to increase. EX.: Null: Two medications are the same. A type I error occurs if the researcher rejects the null hypothesis and concludes that the two medications are different when, in fact, they are not. |
||||||||||||||||||
Error Tipo 2 | False Negative: Failure of rejection of False Null Hypothesis. The probability of making a type II error is β, which depends on the power of the test. You can decrease your risk of committing a type II error by ensuring your test has enough power. You can do this by ensuring your sample size is large enough to detect a practical difference when one truly exists. EX.:Null Two medications are the same. the researcher concludes that the medications are the same when, in fact, they are different |

SIX SIGMA: One Sigma, Two Sigma, Three Sigma, Four Sigma, Five Sigma, Six Sigma... yeah... we got there... is it that simple? SSSFFF currently at one sigma...Statistical Tools allow to predict future failures when past behavior is well understood. For this the variables affecting the process need to be well understood and well accounted. Enter Six Sigma...
ENGINEERING TRENDS: STATISTICS ANALYSIS: All statistical analysis rest on IMPLEMENTATION. All numbers are followed by Human Decision Factors HDF and are Masked by interpretaion of the Statistics. Clear understanding of what the statistic represents and THE LIMITS of the refered to Statistical Analysis will incide in the Decision Making Process DMK. So at the the end of the Analytical process what you need to know is that you have successfully completed a DFSSQBDSASSCARQEQAIQOQFATHTetc... the point is to guide events to ZWR0 error.Statistics are extremely powerful.
Computational power presents the ability of modelling and making very accurate predictions in a variety of PROCESS or SYSTEM model analysis. Although advanced Mathematical Skills allow interpretation it is through experience of MODEL ADJUSTMENT that Statistical Analysis tour-de-forces into a Continous Monitoring Program.
Implementation of Continuous Monitoring Programs are the result of Human and Technological capabilities. Humans place the sensors and interpret data, technology gathers data and accelerates computational calculations. In the End, the role of the Quality Officer / sea un engineer, biologist, statistician, technician, operator / su rol es de 1-Ajustar el proceso para prevenir errores continuos. 2-Predecir modos de fallas para evitar tiempo perdido 3-Desarrollar estrategias que maximizen el uso de recursos 4-Ganar un entendimiento completo del proceso y sus variables para destinar recursos.
Ya entendido esto y habiendo ganado un tren de conocimiento en estadistica aparecen los verdaderos retos de considerar las variables y tomar decisiones que consumiran tiempo y costo. Enter Design of Experiments DOX. Leaders in process inovation understand that the allocation of funds destined to the execution of tasks along with the managerial accumen of project leaders is the half fraction of the process improvement process gains equation. The flow of information from decision to execution may cascade through usually 3 to 5 levels (Cascade Decision Loss). In each step of the two way communication ladder data is Lost, Misinterpreted, mistakenly calculated, held back by professional jealousy, held back by impunctuality or even top level project rearrangements. It is in this crucial step that most companies loose their capital. Swift decision execution forecast are backlogged by every single employees ability to carry the execution of the plan without interference from outside influence to the project. Error prediction is an applied science highly valuable and continually reevaluated. The responsibility of managers in adequately interpreting data is also key in maintaining a forward vision of process improvement. Process analysis may get recirculated in the plan-do-check-check-plan cycle without swift determination of task execution. Understanding the 4th dimension is key in making accurate and timely Value Added solutions to improce Company Performance in the era of the information tsunami.
Reconsidering the role of a leader in today's dynamic business models: Who leads a project? the CEO, the Manager, the Team Lead, the leading Tech, the rookie? In some business models the True Leader is the Rookie. The novice is outside the box, has no prejudice, has not formed clans within the company, has not offended the next door cubicle, and is looking to make an impression within the organization. More importantly than imagery, is the actual execution of the task and its measurable impact in daily, monthly and quarterly business goals. In a group of 4 there is a high probability that someone is prioritizing outside of the main focus and seeking to politicize a process advancement by acting in the last second. This is the same as taking the baton from a relay team in the last meter to claim the goal. This strategery is extremely common in the workplace because the work load is compressed. In compressed work loads there is no tracking of what each employee is executing and how the employee is prioritizing tasks, less time there is to rearrange priorities, so each employee is 'free' to jump in the final phase of the project once someone else took it from 1st gear to fourth. Sometimes the manager is aware of the individual and group contributions and eliminates the need for employees to make claims in the meeting spaces. Competition is key but the goal of any company is to align employees with the Common Goal. Microscopic gaining works to foment competition within a division but it may halter progress by creating internal division.
What are some other instances where a manager needs to eye internal conflict?
Normal Probability Plot: | Tests data for normality, skewness, abnormal distributions. See Histogram. |
Histogram | Graphical Representation of numerical data, like. a Bar chart relating the frequency of numerical values. It helps to visualize the type of distribution of the population, wether it is normal or skewed. |
Boxplot | Data is presented in Quartiles, Median, Maximum and Minimum values. |
X-Bar, R-Chart, vs Individual | X-Bar charts the process mean through time. R-Chart charts the process range though time. Range = Xmax - Xmin Always look at R-Chart first. If R-Chart is Out of Control then the X-Bar chart is meaningless. R-Chart Trends: Repeated Values, OOS points.

How is a Non Conformance generated? Again, a non conformance is Detected.
Is a Non Conformance a CAPA? What is a CAPA? No, NCs may trigger a CAPA but an NC in itself is the detection of deviation or error in expected product, packaging or delivery performance.
In the Industrial setting NCs are generated out of the high expentancy of delivering a high quality product. Any minor deviation in expected results is a Root Cause for an NC.
NCs are investigated under several possible root causes stemming from Machine Behavior, Environmental Triggers, or Human Behavior and as such root causes are established when the determining factors have been dully and fully investigated. Machine Behavior takes into account the Tolerance and the acceptable boundary performance of the unit under NC. When a machine breaches Upper or Lower boundaries of performace an NC is triggered. Yet it is possible by Statistical means to detect NCs prior to occurring, like predicting the future.
About Root Causes: Lets Establish Machine-Environment-Human as the three main Root causes. The cause-fault tree is then stemmed from Machine-Maintenance Schedule-Material Failure-Material Reaction-Unknown Material Reaction-Power Failure due to Machine action... then enter Environmental: Rain, Snow, Humidity, Lightning, Power Failure, and other unnatended keys to root an adverse action, then Human: Lack of Training, Lack of Attention, Excessive Overwork, Work Flow Interruptions, Social Interruptions, Error, or Slack. The classification of these Root Causes is set upon by Management in each Site. Managing these Root Causes is key in preventing future failures and understanding -in depth- the root cause is key in establishing the actions to prevent future occurrences. The balance of managing and correcting actions when humans are involved is a delicate subject because most of the times the Root Cause contains several main root causes in conjunction that lead to the NC event recorded.
Denial, Commitment, Ethos, Diligence, Leadership, Accountability, Stewardship, Role Description, Task Load, Past Performance, Training Record, even Personal and Familial issues are brought into the balance equation to determine the root cause of an event. Recall that Process Failures are costly, sometimes very very costly, all the while there are internal competition within organizations that lead to push and pull responsability for the NC. While it is natural for humans to fail, and failure is even expected, it is also natural to -chide blame-......who wants chastisement? who takes blame? who is ultimately responsible and who takes the blame? These are very delicate issues and are at the core of what make up any major company, organization or work structure. It is why here at SSSSFFFF we are interested in learning your perspective in these details. How does Culture, Polical Stability, Economy, and Technology interplay. What are the best models of management and do they work in the corners of Earth? How can micromanagement and laxity coexist? Are there tools to measure this amalgam of Human-Machine-Environment issues or is it fundamentally decided by gut feelings or by numerical calculations? The answer is always yes. Write to us at info@syntheticforest.net for your perspective.
What are equations governing Tank Loading, what are the thermodynamic ambience of the Tank, what are the clearance and dikes of the walls, are there Firefighting Measures to support a spill. Take the Tianjin Explosion: likely caused by either an Error in Loading, or an Error in Ventilation. The magnitude of tank explosions or BLEVES, Boiling Liquid Expanding Vapor Explosion can be witnessed in Tianjin or simply YouTube BLEVE... Tank safety is very important.
BLEVE 1: Train Car Explosion. Funny how the narrator at 1:10 claims a record was established for a tank blown by a bleve. Not funny that perhaps firefighters died in that explosion. It is why most Plant fires are either immediately contained or let to consume the matter it combusts. Decomposition gases in fires are extremely toxic, many material classes are combusted so fighting the fire becomes a difficult task of both accessing the source to prevent additional combustion and in the selection of fire retardant or fire extinguishing material to add to the flames.
BLEVE 2: The Tianjin Explosion.
Here at SSFF we take matters into accountability for Tank installations. Is your tank for Biotech? Pharma? Cosmetics or Food? Petroleum or Fuels? Gases? There are many considerations into tank work. Take a Fermentor for example. A Fermentor runs a biological reaction that once started it will see its product completed in 30 days. Any basic tank profile or design failure will affect the outcome each and every time, and it could take years to discover that a tank design feature was the root cause of a drop in yield in a site. Take a food tank, is it leaking, is the heat vest broken, are the transfer lines clean? Where good care meets good quality, excelent products emerge. Let us take good of your tank.
Each Tank is birthed through a process involving welders, engineers and inspectors. First select the right material supplier and review the material requested once on-site. Double check to ensure quality, chemical caracteristics, surface polish, electrodeposited finish, etc, is it 3XX? You need to know. The tank will sleep in a bed of rock, or will it need a safety layer underneath to prevent leakage. Was a geologist contacted to study the soil? A stable base is key in ensuring tank safety and longevity. Will your tank arrive prefabricated or will a civil engineer construct the wall. This is called Bunding and Ring Wall Construction. It takes into account natural disaster factors such as storm winds, tornado force shear, earthquake recurrence, and lightning strikes, even tsunami recurrence. So all weld points, joints, bolts and connections need to pass inspection before the next stages. Non destructive Ultrasonic or X Ray tests may be performed to ensure right connections. The roof is lifted and bolted, so now fill it up! Water quality test, corrosion prevention, and stirring measures should follow in place.
Next up Piping: What are the inlet and outlet pipings into a tank? Ball Valves, Needle Valves, Butterfly Valves, Diaphragm Valves, Gaskets, Seals, Metals, and Ratings. Where does the piping run from. Are there any intersections that flow into or out from the tank. What are the friction losses and how to account them. What is the tank insulation and Piping insulation. You need to understand blueprints to understand the flow into a complex installation. Usually tank are grouped in buldings called tank farms. Many pipes will flow into and out from the tank farm so it is of utmost importance to properly trace flow and to note any changes from blueprint to physical reality. A single change can mean a drop in quality or a loss of millions due to pressure losses or material product contact with a misplaced flow regulation unit.
Are there any environmental factors affecting the Tank use or is the tank heat cooled or coil warmed? All tanks have temperature operating ranges that ensure the quality of the materials inside. Here at SSSSFFFF we care about ensuring your tank's alarms are in place and that each valve works where it is intended and as intended. So tanks are a bit civil, mechanical, chemical and electrical.
Are you installing a Tank? Inspecting a Tank? Let us know. Our Engineers will Reach your Tanks to meet your cost and production requirements.

TEST METHOD VALIDATION: Experiments rating Test Method Performance. Test Method Validation involves editing and executing protocols (the METHOD) to test the adequacy of a given analytical procedure (the TEST), and by analytical we mean any activity that is measuring an observable wether qualitatively (categorical) or quantitavely. Test Method Validation answers the following questions:
Can the measurement system adequately discriminate between different parts?
Is the measurement system stable over time? Is the gauge response linear?
Is the measurement system accurate throughout the range of parts?
Does a gauge require Recalibration?
Is there any difference in measurement methods, or operators measuring the same part?
Test Method Table | |
---|---|
Accuracy |
Closeness between the average of one or more test results and an accepted reference value. Involves selecting a Standard or Reference point if none is available. ICH: minimum of 9 determinations over a minimum of 3 concentration levels covering the specified range (for example, three concentrations with three replicates each). Accuracy should be reported as percent recovery by the assay of known added amount of analyte in the sample or as the difference between the mean and the accepted true value, together with the confidence intervals. |
Precision | the closeness of agreement among test results obtained under prescribed conditions. |
Repeatability | Operator. The ability of an operator to consistently repeat the same measurement of the same part, using the same gage, under the same conditions. Closeness of the agreement between the results of successive measurements of the same part, carried out under the same conditions of measuremen (same operator) The ICH requires repeatability to be tested from at least 6 replications measured at 100% of the test target concentration or from at least 9 replications covering the complete specified range. For example, the results can be obtained at three concentrations with three injections at each concentration (3x3) |
Reproducibility | Gauge. The ability of a gauge to consistently repeat the same measurement of the same part, using the same gage, under the same condition. Closeness of the agreement between the results of measurements of the same part carried out by different operators. Also called Ruggedness. |
Linearity | Indicates that gage response increases in equal increments to equal increments of stimulus Beers Law A=eABC Evaluated graphically, in addition to or as an alternative to mathematical evaluation. The evaluation is made by visually inspecting a plot of signal height or peak area as a function of analyte concentration +-5% of expected response is considered linear. |
Range | The values within which a measuring instrument is capable of measuring or which a generating instrument is capable of generating. ICH defines the range of an analytical procedure as the interval from the upper to the lower concentration (amounts) of analyte in the sample (including these concentrations) for which it has been demonstrated that the analytical procedure has a suitable level of precision, accuracy and linearity ICH requires the minimum specified range to be 80 to 120 percent of the test concentration on Assay Tests. |
Uncertainty | Interval around a group of measurement on which a certain measurement will fall. |
Bias | Systematic selection resulting in a measureable difference between the reference value and the expected value. |
Limit of Blank LOB |
LoB is the highest apparent analyte concentration expected to be found when replicates of a blank sample containing no analyte are tested. LoB = meanblank + 1.645(SDblank) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2556583/ |
Limit of Detection LOD | LoD is the lowest analyte concentration likely to be reliably distinguished from the LoB and at which detection is feasible. LoD is determined by utilising both the measured LoB and test replicates of a sample known to contain a low concentration of analyte. LoD = LoB + 1.645(SD low concentration sample) The lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) within a stated confidence limit (generally 1%). Lowest detectable quantity but not necessarily proportionally quantifiable. Expressed in terms of Noise level S/N = 2-3 |
Limit of Quantitation LOQ | ICH defines the limit of quantitation (LOQ) of an individual analytical procedure as the lowest amount of analyte in a sample which can be quantitatively determined with suitable precision and accuracy. Quantitation limit is the lowest concentration of analyte in a sample that can be determined with acceptable precision and accuracy under the stated experimental conditions. LoQ is the lowest concentration at which the analyte can not only be reliably detected but at which some predefined goals for bias and imprecision are met. The LoQ may be equivalent to the LoD or it could be at a much higher concentration. Expressed in terms of Noise level S/N = 10-20 Expressed in terms of RSD% |
Recovery Data | Data is run in 80, 100, and 120% of label claim are run in duplicates or triplicates to serve as backup. |
Specificity/Selectivity | Difference in Multiple Injections of a Homogeneous Sample. Presented as RSD = std deviation / mean Indicates Precision (Repeatability). |
System Suitability | Instruments, Reagents, Columns and Analysts are working properly. Instrument Qualification-Method Validation-System Suitability: set of internal controls to ensure the unit performs as intended. |
Method Validation | After qualifying a measuring unit a method to operate the unit is written. Method Validation is Instrument Specific and should demonstrate that under the method the machine is able to reproduce results as expected for standard values. During Method Validation the Acceptance criteria for the method is defined. |
Tailing | |
Sampling Plan | |
Reference Standards | Internal Standard: Sample with known purity and no interaction with the analyte is inserted into sample. Quantitation is measured as the ratio of detection of one peak to another. |
Acceptability Criteria | |
Stability Testing | Estimates the allowed time span between sample collection and sample analysis. It is also important to evaluate an analytical method’s ability to measure drug products in the presence of its degradation products. Stability is tested by comparing the instrument response with that of freshly prepared solutions. System stability is determined by replicate analysis of the sample solution and calculation of the RSD of the responses. System stability is considered appropriate when the RSD does not exceed more than 20% of the corresponding value of the short term system precision. |

Validation is needed to make sure a developed procedure fulfill the purpose for which it was designed for. Full validation is needed for New Methods or when major changes to an existing method affect the scope.
Partial validation is performed on previously validated methods that have undergone minor modifications. Generally, fewer tests are needed and are based on the potential effects of the modifications.
Cross-validation can be used as a means of assessing inter-laboratory execution of the same method.
