Connect Quality with Performance

Knowing what DONE looks like begins with the Integrated Master Plan.

Recognizing what DONE looks likewhen it arrives means measuring the planned Technical Performance.

Measuring Physical Percent Completetells us how far we have moved toward DONE by calculating the “Earned Value” we’ve achieved.

Connecting Earned Value, Technical Performance, and Physical Percent Complete in the IMP establishes a credible measure of Progress to Plan.

Without these four elements we don’t have a clue to what DONE looks like or if we’ll ever get there as planned.

Definitive measures substantiating the Accomplishment maturity level. Completion of specific work that ensures closure of a specified Accomplishment

Major program milestones or assessment events that substantiate system maturity (initial, progress, or final). These milestones or assessment events deliver the specific capabilities for the system on planned dates.

A WBS can be displayed as a “linear” List. Program Cost is often Calculated by summing the Costs of All Items on That List … but that ignores correlation and basic math: distributions don’t add that way.

Technical performance measurement have often been treated as an engineering function only, not typically linked with EVM, although it shares a common, almost identical, language structure with EVM.

The Schedule Network is Nonlinear, and Program Duration Cannot be Calculated by Adding Together the Durations of All Activities in the Network. And since time is money it is important for schedule slips to reflect cost

Neither cost performance nor schedule performance nor technical

performance measurement can be fully evaluated by itself.

Page 13: Physical Percent Complete - june 2010 (6)

How to Define DONE

Determine Physical Percent Complete based in performance measurement– Compare actual performance against an integrated baseline planned performance of the

integrated cost, schedule and technical goals.

This measurement is possible within a performance measurement system– Use the organization’s internal management control system to provide decision makers with

specific performance information about the progress and expenditures against the planed progress and expenditures.

In many projects where EVM systems are implemented, what a CAM determines (“eyeballing”) as physical percent complete often differs from what is reported via the EV techniques. – This disconnect in measurement of “done–ness” is a clear sign that a cost, schedule and/or

technical performance problem is going to materialize before the PM can properly react.

A Really Simple Example of Physical Percent Complete

17

Painting a room is simple example to focused on a notion of percent complete.

What are the measures of physical percent complete?

‒ Design basis complete and verified

‒ Hardware platform increasing capabilities

‒ Software system increasing capabilities

‒ Integration and test of 1st flight article

‒ Operational verification and validation complete

Where can we look for these measures of physical percent complete?It’s Obvious – in the Integrated Master Plan’s Accomplishment Criteria

But how about a flight avionics system?

Page 18: Physical Percent Complete - june 2010 (6)

18/30

Page 19: Physical Percent Complete - june 2010 (6)

The notion of measuring physical percent

complete is at the core of every project

management method.

It answers the question of what DONE is

in units of measure meaningful to the

program.

This helps us determine answers to

questions that include, but are not limited

to:– What does DONE look like for today, for this

week, or for this month?

– What does DONE look like for entry/exit into

the technical review?

– What does DONE look like for quality control?

– What does DONE look like for the customer?

No stretching the truth

is allowed once we

start using Technical

Performance

Measures with

tangible evidence.

The increasing maturing of a product or service is described through Events or Milestones, Accomplishments, Criteria, and their Work Packages or Planning Packages.

Each Event or Milestone represents the availability of one or more capabilities.

The presence of these capabilities is measured by the Accomplishments and their Criteria.

Accomplishments are the pre–conditions for the maturity assessment of the product or service at each Event or Milestone.

This hierarchy decomposes the System Capabilities into Requirements, Work Packages, and the activities which produce deliverables. This hierarchy also describes increasing program maturity resulting from the activities contained in the Work Packages.

Performance of the work activities, Work Packages, Criteria, Accomplishments, and Events or Milestones is measured in units of “physical percent complete” by connecting Earned Value with Technical Performance Measures.

OUTPUT

When it comes right down to it, the IBR is all about the technical baseline.

IBRs should accompany each major baseline evolution.

In the end, the question implicitly asked of the PM each time is:

“What is your confidence level in your program’s ability to hit cost, schedule, and scope targets

associated with your technical baseline”
