EMIS 7307 Chapter 6
  • Figure 6.40 shows SEMP’s central role.
  • Along with the SEMP comes the need for the work breakdown structure (WBS).
    • Breaks the work into manageable pieces.
    • Provides specific places to accumulate costs.
      • FFP internal use.
      • CPF customer and internal use.
chapter 621
EMIS 7307 Chapter 6
  • Statement of Work (SOW)
    • Shorter is better
    • Make sure that the work you want to be chargeable under the contract is included. Converse is true too!
      • If you are unsure and you trust your contractor then perhaps some vagueness is prudent.
      • Otherwise, frequent SOW changes, which are as ‘painful’ as contract changes, will be necessary.
chapter 622
EMIS 7307 Chapter 6
  • SOW (cont’d)
    • CORs, DLA, and DCMA are responsible to make sure work performed is in scope.
  • Fig 6.6 contains typical System Engineering tasks for a SOW.
chapter 623
EMIS 7307 Chapter 6
  • Program schedules, things to know.
    • Based on experience and educated estimates.
    • When using PERT/CPM first build a network of activities that shows the interrelated events through the life of the program
      • Start at the end and work backwards.
    • Next develop three estimates: the optimistic, pessimistic and the most likely times for each event.

  • Program schedules—things to know (cont’d).
    • What does the term “critical path” mean?
      • Longest or shortest path through the network?
      • See Fig 6.19 on page 282.
    • What does the term “slack” mean?
    • What does the term “crunch” mean?
chapter 625
EMIS 7307 Chapter 6
  • Cost estimates.
    • Rough order of magnitude (ROM)
      • +/- 30% .
      • Distressing when proposals are always more than ROM!
    • Cost estimates are expected to be +/-5%.
  • See Figure 6.27
    • Typically where is most the cost?
  • See last paragraph page 305.

Risk

  • Avoidance
  • Control
  • Acceptance
  • Transfer

See pages 138, 139 in SE Handbook.

technology readiness assessment
EMIS 7307Technology Readiness Assessment
  • Why and How We Use Technology Readiness Levels (TRL).
    • Technology Readiness Levels (TRL) 1-9 as defined by NASA.
    • Goal is for all high-risk items to reach TRL 5/6 by PDR.
    • A project that reaches TRL 6 or higher by the start of Phase C/D is likely to stay within 15% of the baseline cost estimate made at the start of Phase C/D. (NASA analysis)

EMIS 7307
  • PROJECT CYCLES
  • Pre-Phase A = Advanced studies = Preconceptual planning
  • Phase A = Concept exploration = Conceptual design = Preliminary analysis
  • Phase B = Preliminary design = Product/Program definition
  • Phase C = Detailed design
  • Phase D = Construction = Engineering and manufacturing development
  • Phase E = Operations
slide32
EMIS 7307
  • Note: The line between the “technology risk factor ” and the “design and engineering risk factor” is somewhat fuzzy since both involve development. The “technology risk factor” focuses on research and developing the application while the “design and engineering risk” focuses on the detailed implementation of the end-item.

EMIS 7307 Chapter 6
  • BRASSBOARD - An experimental device (or group of devices) used to determine feasibility and to develop technical and operational data. It normally is a model sufficiently hardened for use outside of laboratory environments to demonstrate the technical and operational principles of immediate interest. It may resemble the end item, but is not intended for use as the end item. It is normally built during Advanced Studies / Pre-Conceptual and Conceptual Design /Preliminary Analyses Phases and may be continued in the Preliminary Design Phase.
  • BREADBOARD - An experimental device (or group of devices) used to determine feasibility and to develop technical data. It normally is configured only for laboratory use to demonstrate the technical principles of immediate interest. It may not resemble the end item and is not intended for use as the projected end item. It is normally built during Advanced Studies or Pre-Conceptual and Conceptual Design Phases.
