Some Confusing Terminologies.
|Analogous vs parametric Estimating||
Analogous Estimating use Expert Judgement (as in the actual experience from a person) to compare a similar project and provides rough estimates.
|Configuration Control vs Change Control||
* Configuration Control is the activity of managing the product (or project's deliverables) and related documents, throughout the lifecycle of the product.
|Project Schedule vs Schedule Baseline||
Schedule Baseline is an "approved" version of the Project Schedule
|Enhance vs Exploit||
Enhancing is about increasing the probability of the occurrence of the event. Here, though the measures will be taken to increase the chance of happening of the event, but no surety to realize it.
|Close Project/Phase vs Close Procurements||
|Quality Assurance vs Quality Control||Quality Assurance
* Quality Assurance is a method which makes sure that any process developed to generate product is such that the product that comes out from the process must be fit, and conforms to all stated requirements. To develop the process, Quality Assurance takes input from the Quality Control Process.
* Quality Assurance is a proactive process, and starts at the very beginning of the project to understands the stated requirements, not stated requirements, expectation, and creates a plan to meet those requirements and expectations.
* Quality Audit is an example of Quality Assurance. Other examples are training, process definition, and selection of tools etc.
The primary purpose of Quality Assurance is to prevent defects in deliverables at the planning process stage itself to avoid rework.
* Quality Control is a product based approach and is concerned with the operational activities and techniques those are used to fulfill the requirements of quality.
* The Quality Control functions starts once the projects work has begun. It is a reactive approach and helps to find defects in deliverables. Site inspection and testing etc. are examples of the Quality Control Process.
* Main purpose of the Quality Control Process is to see if the deliverables are defect free, acceptable as per quality requirements and standards set in the Quality Assurance process. If deliverables are not as per requirements, suitable corrective action will be taken.
* Quality Assurance, and Quality Control processes are dependent on each other. The Quality Control receives the input from the Quality Assurance, and in turns gives feedback to the Quality Assurance so that Quality Assurance could validate the process.
* For example, if the project team finds any defects while executing the project, it will correct the error by work around and this feedback is sent to Quality Assurance for further investigation to take corrective actions in the process so that this error should never happen again in future. In the same way the Quality Control people will follow the process defined by Quality Assurance so that these defects do not recur.
