  1. Chapter 10System Engineering

  2. The Hierarchy

  3. Business Process Engineering • uses an integrated set of procedures, methods, and tools to identify how information systems can best meet the strategic goals of an enterprise • focuses first on the enterprise and then on the business area • creates enterprise models, data models and process models • creates a framework for better information management distribution, and control

  4. The BPE Hierarchy • Information strategy planning (ISP) • strategic goals defined • success factors/business rules identified • enterprise model created • Business area analysis (BAA) • processes/services modeled • interrelationships of processes and data • Application Engineering • a.k.a ... software engineering • modeling applications/procedures that address (BAA) and constraints of ISP • Construction and delivery • using CASE and 4GTs, testing

  5. Information Strategy Planning • Management issues • define strategic business goals/objectives • isolate critical success factors • conduct analysis of technology impact • perform analysis of strategic systems • Technical issues • create a top-level data model • cluster by business/organizational area • refine model and clustering

  6. Business Area Analysis • define “naturally cohesive groupings of business functions and data” (Martin) • perform many of the same activities as ISP, but narrow scope to individual business area • identify existing (old) information systems / determine compatibility with new ISP model • define systems that are problematic • defining systems that are incompatible with new information model • begin to establish re-engineering priorities

  8. Product Engineering

  9. Requirements Engineering • Elicitation — determining what the customer requires • Analysis & negotiation — understanding the relationships among various customer requirements and shaping those relationships to achieve a successful result • Requirements specification — building a tangible model of requirements

  10. Requirements Engineering • System Modeling — building a representation of requirements that can be assessed for correctness, completeness, and consistency • Validation — reviewing the model • Management — identify, control and track requirements and the changes that will be made to them
