Software Quality and Software Engineering What is software? Types of software. What does “Quality of Software” Mean? What is meant by Engineering? How and why do you engineer software?

Software Development New software Extension and newer versions Validity – from user perspective Speed in capturing and translating ideas and needs Efficient implementation and deployment Effective maintainability Continuous improvement

Software Quality What do we mean by Software Quality? How do we ascertain it? What should we do to achieve it? Why is software quality essential? How does it help? Tools to achieve quality!

Software Engineering What is meant by Software Engineering? What are the main topics of SE? When does it start and when does it end? http://www.rspa.com/spi/ For your own understanding – list topics in SE, Advanced SE, from web/conference publications.

UML Picture is worth a thousand words (?) Design that states ones thoughts Precise Unambiguously Language Structures and syntactic rules Completeness Universal applications

UP Language can be abused Methodology assists in staying on track Effective Process of software development Standards, Documents, Tools Architecture, Use and Risk Iterative development

Software Development Phases Inception Elaboration Construction Transition Each phase has five core workflows Requirement Analysis Design Implementation Test

Inception Phase Vision – what is the product, its goals, and its specialty. Introductory UI Preliminary list of users, uses and requirements. We will firm up the vision and list of user Research, Feasibility argument and business case

Elaboration Phase Identify details of the uses and any unspecified requirements and uses. Analyze details of the users and uses as well as intermediary elements. Create test scenarios. Establish tools and systems needs as well as dynamic behavior of the system. Design the software with details necessary for implementation with maximum flexibility for change. Re-visit requirements and needs w.r.t. Vision

Construction Phase Identify languages, developers, schedules, test methods and field test process. Implement and test version 1. Ensure adherence to the design documents. Iteratively – enhance implementation details and ensure unit tests are performed. As implementation matures thoroughly perform integrity and overall tests. Develop technical manuals and training programs – for installation as well as users. Start field tests and integrate feedback (or add to requirements document).

Transition Phase Sell and ship. Assist in customer installations and training. Customer service – online as well as telephone. Track feedback for validation, corrections, and enhancement purposes. Watch the competition!

Inception -- establish the business case and define scope for your project, while determining the tools to be employed. Elaboration -- validate requirements, establish a baseline for the architecture, and mitigate the highest risks. Construction -- develop, integrate, and test all components of your project's application. Transition -- make the software you created available to the user community and ensure that user expectations are met.
