Summary
What Constitutes a Business System?
Analysis and design can be focused and brief
Investigate and identify problems, opportunities and objectives
Analyze current systems and document requirements
Present findings and alternatives
Designing the improved system
Developing, documenting and testing the custom application

Implementing, evaluating and maintaining the new system
Implementing the new system involves user training, the successful conversion of data from the old system to the new, upgrading and/or installing any needed equipment to support the system, and bringing the new system on-line.

Although evaluation should be taking place in every phase of analysis and design, users often cannot predict what issues will arise until the new system has been implemented. This is often the first opportunity users have to experience the application as a whole, and thus to critique what and how the application performs in relation to their expectations and experience. Implementing should include ongoing user evaluation of the system after installation.

Maintaining the new system involves an ongoing cycle in response to the need for bug fixes, hardware/software updates, business system process changes and implementing additional features requested by users or management.
