The hierarchy

The Hierarchy


Business process engineering

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


The bpe hierarchy

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, testing


Information strategy planning

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


Defining objectives and goals

Defining Objectives and Goals

  • Objective—general statement of direction

  • Goal—defines measurable objective: “reduce manufactured cost of our product”

    • Subgoals:

      • decrease reject rate by 20% in first 6 months

      • gain 10% price concessions from suppliers

      • re-engineer 30% of components for ease of manufacture during first year

  • objectives tend to be strategic while goals tend to be tactical


Business area analysis

Business Area Analysis

  • define “naturally cohesive groupings of business functions and data”

  • 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

Product Engineering


Requirements engineering

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


Requirements engineering1

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
