System Testing There are three main kinds of system testing: Alpha Testing: System testing is carried out by the test team within the developing organization. Beta Testing: System testing performed by a select group of friendly customers. Acceptance Testing: When the software is ready to hand over to the customer it has to go through last phase of testing where it is tested for user-interaction and response. This is important because even if the software matches all user requirements and if user does not like the way it appears or works, it may be rejected.

Software Project Planning OBSERVATIONS ON ESTAIMATING o Estimation of resources, cost, and schedule requires experience, access to good historical information, and to do prediction. o Project complexity has a strong effect on the uncertainty inherent in planning. o Complexity is a relative measure o Project size is another important factor that can affect the accuracy and efficacy of estimates. o As size increases , the interdependency among various elements of the software grows rapidly. o The degree of structural uncertainty has effect on estimation risk. PROJECT PLANNIN OBJECTIVES The objective of software project planning is to provide a framework that enables the manager to make reasonable estimate of o resources, o cost and o Schedule. SOFTWARE SCOPE: The first activity in software project planning is the determination of software scope. Software scope describes o the data and control to be processed, o function, o performance, o constraints, o interfaces, and o reliability. OBTAINING INFORMATION The analyst might ask o Who is behind the request for this work? o Who will use the solution? o What will be the economic benefit of a o Successful solution?

o Is there another source for the solution ? Resources o The development environment-hardware and software tools-sits at the foundation of the resources pyramid and provide the infrastructure to support the development effort. o In the higher label reusable software components software building blocks that can dramatically reduce development cost and accelerate delivery. o The primary resource is people . Characteristics of resources are - o Description of the resources o A statement of availability o Time when the resource will be required o Duration of time that resource will be applied Summary o Software project planning begins with the set of activities. o Before the project can begin, the manager and the software team must estimate the work to done, o The resources that will be required, and the time that will elapse from start to finish.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
