Why software testing effort estimation is important after functional specifications finalization phase?

If we go by quality standards the sizing of software testing effort has to be done before the tester(s) start writing the test cases for the purpose. The estimate will clearly draw out of the functional specifications signed off between the customer and vendor. Without sizing the Testing manager can never create a testing plan based on which he will decide the number of days and persons required to write test cases, perform testing, draw out the testing results, submit the result report to development team and get the reported bugs resolved. The plan will comprise of time-line and no. of persons required for each of this phase in the sequence mentioned above.

To calculate a reasonable testing time-line estimate based on functional specifications there are certain guidelines that need to be followed: the person who is planning has to have ample business and testing knowledge. Unless (s)he has the right business knowledge (s)he will not be able to select the right persons for writing test cases, or able to guide them on the critical business rules and processes written in the software to hit upon. In that case the best of the test cases will lack the complete coverage and accuracy in testing. The software may lack bug-proofing at the end and customer will be the sole sufferer. Ultimately it is going to effect the software, and the organization that built it.

Software Quality vs Project Quality

The definition of QUALITY varies in different contexts. On one hand we talk of software quality that means adopting standards and measures to ensure the building of software product that meets all customer requirements (design, interface, business requirements, functional requirements etc.) and ready to deliver. On the other hand when we talk of Project Quality, we mean the standards and measures by means of building (or adopting) to ensure the success in terms of time and revenues of a complete project right from its initiation till the implementation stage that keeps continuing at post implementation stage also.

In context of software – the quality means – software strategy, plan, text cases, test scenarios, test results and fixing of bugs. Inclusion of quality in this context will vary from organization to organization and project to project (within an organization). This will ensure the successful building of software product ready for delivery.

In context of project – the quality would mean – managing quality standards and measures for a project right from its initiation to all stages coming forth. A project lifecycle in standard terms would comprise of Project Initiation, Project Planning, Development Execution, Implementation execution, Project Close-out, and post implementation phase broadly, which remains on-going till the software built is in use by the customer for a period of years.

The subject matter can continue on pages and pages, but the crux is – software quality is merely a subset of project quality, and even if we have world class standards in software quality, it does not ensure a successful project lifecycle.
