Physical Design & Integration Phase

Purpose of phase is to:

1. Transform Business Requirements into Physical Design specifications

• How technology will be used in system (will be constrained by architectural model from previous phase)?

Tasks:

Systems Design (Integrating Commercial Software – Buy Solution)

4.1 Research Technical Criteria & Options

4.2 Solicit Proposals or Quotes from Vendors

5A.1 Validate Vendor Claims & Performances

5A.2 Evaluate & Rank Vendor Proposals

5A.3 Award (or Let) Contract & Debrief Vendors

Systems Design (In-house Development – Build Solution)

5.1 Design the Application Architecture

5.2 Design the System Databases

5.3 Design the System Interface

5.4 Package Design Specifications

5.5 Update the Project Plan

Technology based views of a System:

• Physical database Design Specifications
• Physical business process & software design specifications

Feasibility Checkpoint: GO or NO-GO?

Participants:

• System Designers
• System Analysts
• System Users

Deliverables:

• Combination of:
• Physical Design Models & Specifications
• Design Prototypes
• Redesigned Business Processes

FAST Phases

Framework for the

Application of

Systems

Thinking (representative systems development process).

FAST Phases are more detailsed than the classic phases:

• Scope Definition
• Problem Analysis
• Requirements Analysis
• Logical Design
• Decision Analysis
• Physical Design & Integration
• Construction & Testing
• Installation & Delivery
