The Planning Fallacy
Why AllYour Projects Are Always Late – andWhat to Do About It

Optimism Bias
Overconfidence
The Planning Fallacy
Coordination Neglect
Procrastination
Adaptiv
e
Makes us Feel Better
We are Rewarded for it
(as a society)
Failure to recognize
how hard it is to
put stuff together
when others are
involved.
Complexities of
combined outputs
Impulse
Control
Why Does it Happen? What Goes into It?
The Basics (our biases)
Danny Conoman
Nobel Price -
Economics
His Thoughts: The Planning Fallacy
Strategic Misrepresentation
Deliberate – Incentivized
to misrepresent the
business case. Project to
look good on paper to
increase changes of
getting funded.
Underestimating the cost
and overestimating the
benefits.
Create an intentional high
benefit/cost ratio.
Why Does it Happen? What Goes into It?
Something a Little More Complicated (politics)
“If you realistically present to people what can
be achieved in solving a problem, they will find
it completely uninteresting.”
“You can’t get anywhere without some degree
of overpromising.”
What are the Results of
The Planning Fallacy’s Output?
Incorrectly Defined
Project Expectations
Under-Estimated Project
Scope
(Schedule/Budge
t)
People are hired to meet
unrealistic budgets and
schedules.
When not met, people lose
their jobs or opportunities
for promotions.
Companies contracted lose
their credibility or
contracts as the
accountability is
distributed.
The Human ImpactsThe Intangible Impacts
As budgets and schedules
slip, people begin to blame
one another.
Initiatives can change from
completing a project to
protecting and maintaining a
job/credibility (reputation).
Cost and Schedule impacts are tremendous during this
phase of a project. New teams typically come in and the
schedule and scope are reset. Stress and reputations can
take a toll on health and future career or business
outcomes.
Too often Projects are
Started by people who
never finished them.
Develop & Maintain a Database
Algorithms
Mitigating for:
The Planning Fallacy
Strategic Contract Incentives
Price-in the Optimism
Bias & use Reference
Class Forecasting
Analytics on how
much the schedule
and estimate are
underestimated for
this type of project.
Incentivize for targets met
and punish for targets not
met.
Now What?
What are we Supposed to Do?
If on average,
similar projects go
over budget by X%,
add same X% to
planned
budget/schedule.
Overcome Algorithm Aversion.
Use Data instead of Human
Judgement to make
Forecasts.
Identify & Compare to
Similar References
Too often Projects are
Started by people who
never finished them.
