Document Summary

Week 2: chapter 1: introduction to systems development. Neither team members nor the user completely understands the problems and complexities of a new system. Allow, anticipate, embrace changes and new requirements during development process. Core components developed first, additional components are added. Week 2: chapter 8: approaches to system development. New information system can be developed according to the plan. Phases: project initiation, project planning, analysis, design, deployment, support. Implementation: assumes phases can be carried out and completed sequentially, no going back, rigid planning, final decision-making at each step. Assumes project must be more flexible and adapt to changing needs as project progresses. Spiral model: some analysis, some design, some implementation, more analysis, more design, more implementation, even more analysis, even more design, even more implementation. Provides complete front to back implementation of the new system but with only bare bones of functionality. Gets working software into hands of the user early.
