Systems Engineering Planning

Objectives

• Chapter 7 in the Textbook.

• SEMP is introduced but not covered.

• Define the Systems Engineering Management

approaches.

• Define the Project Engineering alternatives.

• Discuss tailoring of the Systems Engineering

process.

• Discuss the purpose of the Systems Engineering

Management Plan (SEMP).

Key Terminology

• Engineering systems

• Lifecycle options

• System Engineering Management Plan (SEMP)

Systems Engineering Planning

• Determines how the systems engineering process is to be

accomplished and controlled to meet project objectives.

• Ensures proper balance of quality, cost, schedule, risk, and

performance.

• Provides a tailored integration and coordination of the project

engineering system.

• Provides the technical management plan, via the publication of a

Systems Engineering Management Plan (SEMP) , for the integration

of all engineering activities.

• "Plans are nothing, planning is everything.”

–– General Dwight D. Eisenhower

Different Kinds of

Development or Lifecycles

• Sequential (waterfall-like)
  • Title Design
  • DOD
  • VEE
• Incremental
• Evolutionary
  • EVO
  • Spiral
• Rapid Application (Rapid Prototyping)
• Competitive Piloting
• Framework Architecture
• Design-to-Cost
• Re-engineering existing systems
• Reverse Engineering
• Platform Model

DOD Model – Waterfall – Do it Once,

Right

Waterfall – Generally without the

feedback

Incremental, Model Based System
