Measure of Effectiveness (MoE)
Measures of Effectiveness …
• Are stated in units meaningful to the buyer,
• Focus on capabilities independent of any technical
implementation,
• Are connected to the mission success.
Operational measures of success that are closely related to
the achievements of the mission or operational objectives
evaluated in the operational environment, under a specific set
of conditions.

satisfy the MoE.
Measures that characterize physical or functional attributes
relating to the system operation, measured or estimated
under specific conditions.

❷ DEVELOP A PLAN FOR
TECHNICAL SUCCESS
The Technical Plan shows the sequence of work needed to
produce products and services that move the program toward
Done.
The Technical Plan can take many forms. From a formal Integrated
Master Plan / Integrated Master Schedule to a Kanban work plan or
Scrum Release/Sprint/Task Plan in Agile Software Development
TC
16. 16
Develop the Plan and Schedule
• Define the technical approach to building the product that will
allow it to meet the performance and effectiveness goals
– Identify all the variables that will impact the solution to the
technical and operational requirements
– Orville and Wilbur used the spiral development approach for
the Wright Flyer
• Sequence the work to assure the increasing maturity of the
deliverables supports the plan to reach Done.
TC
17. 17
The Wright Brothers’ Technical Plan
• Modify aircraft to reduce weight from 845 to 800 pounds
• Modify aircraft and controls for two persons

❸ DEFINE THE
PROGRAMMATIC PLAN
The Programmatic Plan describes all the activities that enable the
Technical Plan to function properly. What work do we need to do in
what order and what’s the cost of that planned work.

reach done as planned.
RP
19. 19
Define the Programmatic Plan

❹ ADJUST FOR REDUCIBLE
AND IRREDUCIBLE RISK
Any impediment reduces the probability of success. Each
impediment must be identified, a plan to address the impediment
developed, each handling strategy applied, monitored, and
measured to assure there is an increasing probability of success.

❸ REVISE IMS AND RISK
REGISTER
With this data, update the Integrated Master Schedule and Risk
levels in the Risk Register for future periods of performance.
51. 51
Revise IMS and Risk Register
• Every reporting period update the Risk Register with actual
assessment of
– Reduced risks
– Actual margin needed for unmitigated and irreducible risks
• Adjust Risk Register contents for current assessments
– New risks
– Retired risks
– Changes in risk attributes
• Update ETC, EAC, and ECD with the statused IMS and Risk
Register
TC
52. 52
❹ RUN AND RERUN THE
SCHEDULE RISK ANALYSIS
Schedule Risk Analysis (per DI-MGMT-81861) at periodic intervals
to confirm the Estimate to Complete and the Estimate At
Completion are still within acceptable values to ensure the
probability of program success.
TC
53. 53
Run and Rerun Schedule Risk Analysis
• With updated Risk Register – rerun the Schedule Risk Analysis
• Reassess EAC, ECD, and ETC
• Determine sensitivity indices (which elements are most likely to
cause the forward plan to go awry)
• If needed
– Replan IMS, possibly with more schedule margin
– Add resources
– Adjust technical solution
TC
54. 54
Summary
• Cost and Schedule performance informed by Technical
Performance
– At IBR TechnicalPerformance plan defines the work activities
in the IMS
• Build a risk adjusted PMB
– Reducible and irreducible risks in the risk register, traceable to
the IMS.
• Budget active mitigation activities
• Protect unmitigated risks with ManagementReserve and
Schedule Margin
• Make sure programmatic data is aligned with Technical
Performance Data
• Perform these activities continually during execution to Keep the
Program Green
