INTEGRATING RISK WITH EARNED VALUE

PIKES PEAK REGIONAL CHAPTER PROJECT MANAGEMENT PRODUCTIVITY TOOLS

SYMPOSIUM SATURDAY, FEBRUARY 28TH, 2009

GLEN B. ALLEMAN

The notion of integrating cost, schedule, technical performance, and risk is possible in theory. In practice care is needed to assure credible information is provided to the Program Manager.

Page 2: Integrating Risk With Earned Value

Today's Learning Objectives Cost, Schedule, Technical

Performance, and Risk Are

Inseparable

All numeric values of cost,

schedule, technical

performance, and risk

assessment are random

variables drawn from some

underlying probability

distribution

Managing these variables

must be done through the

eyes of a Risk Manager 2

Page 3: Integrating Risk With Earned Value

There are

usually two

phases to many

projects …

1. Too early to tell

2. Too late to stop

Page 4: Integrating Risk With Earned Value

The Fundamental

Program Management Question

Can we plan with

sufficient accuracy, to

allocate resources to

reduce risk while

meeting requirements,

and obtain timely

feedback in order to

adjust plans and

performance goals?

Management Systems Gets Mixed Up When We

Try to Put Them Together

Page 9: Integrating Risk With Earned Value

Every Program Manager Should Know…

When will this project finish?

What is the statistical confidence in this date?

Is the project’s schedule realistic and achievable?

What will it cost when we are done?

How is the project performing against its plan?

What deliverables are slipping?

How are we going to get the deliverables back on schedule?

What does past performance say about the future performance?

What is the impact on the schedule of any change requests?

Is there enough schedule slack and cost reserve to cover the risk?

Where is the risk in the schedule?

How can we get the work done sooner to reduce risk?

How can we recover from any foreseen delays?

How can we work around a problem?

ANSI 748B Says on Page 1

Plan all work scope for the program to completion.

Integrate program work scope, schedule, and cost objectives into a baseline plan against which accomplishments may be measured.

Objectively assess accomplishments at the work performance level.

Analyze significant variances from the plan and forecast impacts.

Provide data to higher levels for management decision making and implementation of management actions.

Some Criteria for Successful EVMS Beyond Full Compliance of the 32 Criteria

Define a Work

Breakdown Structure

Identify the

Organizations

doing the work

Integrate WBS and

OBS into a RAM

Schedule all

Planned Work

Indentify Products

and Milestones

Time Phase the

Budget

Record all Direct

Costs

Determine all

Variances

Sum These

Variances

Manage Action

Plans

Incorporate Changes 13

Page 14: Integrating Risk With Earned Value

At The Same Time, Risk Management is

Commonly Misunderstood

It’s not about random chance, it’s about defining

mitigations and retirement plans in the presence of

uncertainty

14

Page 15: Integrating Risk With Earned Value

1. Hope is not a strategy 2. No single point estimate of cost or schedule can be correct 3. Cost, Schedule, and Technical Performance are inseparable 4. Risk management requires adherence to a well defined process 5. Communication is the Number One success factor

Five Fundamental Principles of Risk Management

Page 17: Integrating Risk With Earned Value

But ANSI 748B Also Says …

Identify physical products, milestones, technical

performance goals, or other indicators that will be

used to measure progress.

So why the disconnect between Risk and Earned

Value?

Isn’t the measure of risk, the rate of risk reduction

an “…other indicators…”

SOME ACTIONABLE DETAILS FOR PUTTING THESE FOUR CONCEPTS TOGETHER

In Theory there is no difference between Theory and Practice.

In Practice there is — Yogi Berra

Page 20: Integrating Risk With Earned Value

So much for our strategy of winning

through technical dominance

There are two types of “uncertainty” on any

sufficiently complex program

– Technical – uncertainty about the functional and

performance aspects of the program’s

technology that impacts the produceability of

the product or creates delays in the schedule

– Programmatic – uncertainty about the duration

and cost of the activities that deliver the

functional and performance elements of the

program, independent of the technical risk

We’re interested in connecting the two in the schedule and cost

model(s)

– When the technical uncertainty arises what is the impact on the schedule

and cost?

– When the schedule or cost uncertainty arises what is the impact on the

functional and performance aspects?

The Difference Between

Technical and Programmatic

Risk

20

Page 21: Integrating Risk With Earned Value

Deterministic Versus

Probabilistic Deterministic

• Each activity has a planned value

• For the schedule each task has a

predecessor and a successor.

• The longest path through the

network is the critical path

• The total duration of the project is

a fixed value - it is deterministic

• The total cost is the sum of all the

activity costs

• Risks are defined and handled as

static entities

Probabilistic

• The program elements are not

random, but they are random

variables drawn from a probability

distribution.

• Three point estimates "can" be

used to describe task duration

random variables

• The total duration of the project is

a random number

• The total cost is a random number

• Risks are stochastic processes

that have probabilistic outcomes

for cost, schedule and technical

performance

21

Page 22: Integrating Risk With Earned Value

Lack of predictive variance analysis

Untimely and unrealistic Latest Revised Estimates (LRE)

Progress not monitored in a regular and consistent manner

Lack of vertical and horizontal traceability cost and schedule data for corrective action

Lack of internal surveillance and controls

Managerial actions not demonstrated using Earned Value

Inattention to budgetary responsibilities

Work authorizations that are not always followed

Issues with Budget and data reconciliation

Lack of an integrated management system

Baseline fluctuations and frequent replanning

Current period and retroactive changes

Improper use of management reserve

EV techniques that do not reflect actual performance

Without these Principles The Program Train Wreck Starts When…

AN INTRODUCTION TO SOFTWARE ENGINEERING INSTITUTE’S CONTINUOUS RISK MANAGEMENT (CRM)

CRM is the Software Engineering Institute’s framework for managing risk in the context of system integration, COTS based product development, and the management of these activities.

Page 24: Integrating Risk With Earned Value

Continuous Risk Management has Six Components

Page 25: Integrating Risk With Earned Value

Putting Continuous Risk Management Work

CRM Activity Project Representation

Identify Risk items with IMP/IMS #’s, CA/WP & resource

assignments

Analyze Risk management responsibilities assigned

Plan Mitigation plans with durations and resource

assignments

Track Status reported from Risk Management to IMS

Control Risk tasks reporting in weekly status process

Communicate Integrated Master Schedule (IMS) status reporting

as Physical Percent Complete

PHYSICALLY CONNECTING EARNED VALUE WITH RISK MANAGEMENT

Page 28: Integrating Risk With Earned Value

Some Historical Background†

Cost and schedule growth have been persistent

problems for decades

The use of Earned Value is common in DoD

environments

As is the use of Risk Management

It’s the integration that is missing

† “Integrating Risk Management with Earned Value Management,” NDIA

Report, www.ndia.org

28

Page 29: Integrating Risk With Earned Value

The Core Problems Before We Start

Earned Value is a measure of quantity not quality

Risk measures the probability of an unfavorable

occurrence but rarely monetizes this outcome

Risk management focuses on dealing with future

events

Earned Value focuses on reporting past

performance

The output of Risk+ is a Probability Distribution Function and a

Cumulative Distribution of all the possible dates that “watched”

activity could take.

The result is a picture of the Confidence that the target date of

2/10/3 – can be met.

It shows 40% – which is not good

36

Page 37: Integrating Risk With Earned Value

So with this information we can ask …

What cost impact will there be?

What resource impacts?

What technical dependencies?

What mitigation or retirement plans must be in

place to increase the probability of success to

something greater than 40%?

What other interdependencies are there in the

program?

37

Page 38: Integrating Risk With Earned Value

Program Management is Risky Business

Traditional Approaches Are Seriously Flawed

Risk Management Is Not About Preventing Risk

Risk Management Is About Managing In The Presence Of

Risk

This means managing Cost, Schedule, and Technical

Performance
