Lecture 9

Develop repeatedly. Manage requirements because they are set by customers and can change by users. Divide parts of the system into components to model them and test them individually. Testing should be a major part of the project at any time. A project is usually worked on by multiple developers, so it is important to control changes and synchronize them.

PSP tool is a software the automates data gathering and reporting to help software developers with personal software processing. It provides a place to record data related to your project. For each task you perform, PSP tool allows you to track based on time, defects and code size.

Gather requirements for the project, come up with the main use cases for the core functionality of the project, evaluate the architecture of the software, estimate cost, schedule and risk, provide the business case - what is the business justification and benefit gained from adding that functionality, create a work plan for the following elaboration phase.

create a detailed architecture, validate that the system architecture includes the requirements correctly and finalize it as the official design, develop solid understanding of the use cases, create a plan for the construction phase and demonstrate that the baseline architecture will support the project goals and objectives for a reasonable cost in a reasonable time.

A use case model that is at least 80% done and a use case description that is mostly done, added nonfunctional requirements, a software architecture description and its executable prototype, a revised risk list and business case. a development plan that shows both major and minor iteration and stating deliverables at the completion of each iteration, an optional user manual.

Reduce costs by using resources efficiently and avoiding unnecessary changes or rework. Achieving good quality as rapidly and as practical and achieving useful versions as quickly as possible.
