1. INFS 6225 Object-Oriented Systems Analysis & Design Chapter 12: Construction

2. Construction Activities needed to build the system: –Programming –Testing –Documentation Programming –Job of the programmer –Can be largest component (time & cost) Testing –Primary responsibility of Analysts during Construction Stage

3. Managing Programming More programmers = longer build time (why?) Must have weekly project meetings to discuss changes Create & follow standards Keep effort well organized Use Program Log Work to avoid/minimize Scope Creep

4. Testing 4 Stages of Tests: 1. Unit - focus on single unit (Class) 2. Integration - does set of Classes work together without error 3. System - do all Classes work together without error 4. Acceptance - confirm system is complete & meets business needs alpha testing - use made-up data beta testing - use real data Why should tests include nonsensical data?

5. Documentation 2 Types of documentation: 1. System - help programmers & systems analysts understand & maintain system 2. User -help users understand & use system –Most users begin working with system w/o training & w/o reading user manual –3 hours to write a page of documentation (2 hours per online screen) What are advantages to online documentation?

6. Types of Documentation Reference Documents (Help System) - help user perform specific function Procedures Manuals - how to perform business tasks Tutorials - how to use major components of a system Topics should be written from user’s point of view

7. Navigation Terms Commands in the user interface (Action & Object) Major Concepts in the system Business Tasks to be performed Synonyms - e.g., Quit or Exit
