The Budget Trap
Enterprise Project Estimation with SEER
by
Galorath Incorporated
Estimation Is Critical To Project
Success
•
“The single most important task of a project:
setting realistic expectations…
Unrealistic expectations based on inaccurate
estimates are the single largest cause of (project)
failure.” Futrell, Shafer and Shafer, “Quality Software Project Management”
Some of the most important
business decisions about a
project are made at the time
of minimum knowledge and
maximum uncertainty.
SEER Can Help
•
Answers Fundamental Estimating Questions:
• How much effort is required to complete an
activity?
• How much calendar time is needed to
complete an activity?
• What is the total cost of an activity?
About Galorath
Galorath’s SEER products are used to parametrically
estimate effort, duration, cost, and to gauge risk

How SEER Is Used
•
Project estimates: How much will it cost? How long will it
take?
•
Bid preparation: What price should we set?
•
Should-cost: Are we paying a fair price?
•
Project design: Can we optimize by altering parameters?
•
Planning: How much staff should we allocate?
•
Portfolio analysis: What’s the cost/benefit of this set of
projects?
SEER for “Should Cost”
•
Debbie Wilson of Gartner may have said it best.
“When price negotiations are conducted
with accurate cost models in hand, I
firmly believe that they yield superior
results. That’s because fact-based
discussions support joint problem-solving
and relationship building with key
suppliers far better than just using a
heavier hammer or an alternative
supplier’s hard luck…”

Key SEER Concepts –
Captures What You Know; Simulates What You Don’t








Knowledge based – ready to use out of the box
Risk driven – estimates capture uncertainty
Practical input drivers – intuitive / easy to understand
Comprehensive results – detailed and high level
Enterprise ready – scalable to any organization
Adaptable – utilizes common project patterns
Learning – incorporates your cost history as available
Open - easy to integrate/interface with other systems
Results:
•
•
•
•
•
Accurate project forecasts, schedules & resource plans
Facilitates communication & negotiation with customers
Repeatable & standardized enterprise estimation process
More projects within budget, on time, at specification
Continuous improvement
SEER Enterprise Database
(SEER-DB)
• SQL Server or Oracle
• Allows for collaboration & sharing of estimates
• Can also store estimate modules or component
templates that can be used to build up an estimate

SEER – Probabilistic Estimates
•
SEER uses a range of
inputs to develop
probability
distributions
•
The result is a
probabilistic analysis
of the estimate
•
SEER accepts multiple
sizing units
•
Monte Carlo
simulation provides
project-level
assessments of risk
Least, likely, and most
inputs provide a range of
cost and schedule outcomes
Confidence (probability)
can be set and displayed
for any estimated item

SEER-EOS
SEER-EOS Model
•
SEER EOS Is NOT a weight based estimating
model. Instead, it uses Key Technical/ Performance
parameters (KTPPs) to estimate each technology.
These parameters are judged by subject matter
experts to be important drivers of cost.
•
The KTPPs are supplemented with many of the
standard SEER-H heritage, team, and
programmatic parameters, such as, but not limited
to: New Design, Design Complexity, Developer
Capability & Experience, Production Experience,
Production Quantity, etc.

This approach can provide even concept planners
with an advanced understanding of the cost of
potential designs.

• Business
• Technology
• Legislation/Regulation
•
IT projects and initiatives cover a broad spectrum of
activities
• severs, training, establishing processes, deploying

•
IT managers need estimates that are comparable, yet

Estimation Best Practices
Simple Steps to Improve Your Estimates
Have you been here?!
Estimation Best Practices
•
•
•
•
•
Decide The Purpose And Goal Of Your Estimate(s)
•
•
Re-estimate When Project Changes Or More Is Known
•
•
Estimate Schedule As Well As Effort (Cost)
Have A Documented, Repeatable Estimation Process
Interview Stakeholders
Use “Least, Likely And Most” to Describe Key Inputs
Estimate The Solution Range And Consciously Choose
the Confidence Point For The Plan – 50% or ?
Convert Expert Spreadsheets Into A Common
Language And Clearly Define Terms
Tie The Estimate To The Project Plan
Estimation Best Practices - 2
•
•
Track Progress vs. Estimate Throughout The Life Cycle
•
Evaluate Total Ownership Cost; Development +
Ongoing Maintenance and Support
•
Have Clear Definitions: What does “complete” mean?
Tracking Defects (Both Discovery And Removal)
Improves Cost, Schedule, And Reliability Outcomes
• What activities are included or excluded? (Development
only or total ownership; help desk support, etc.)
• Which labor categories are included or excluded in the
estimate? (Are managers included? Help desk staff?)
•
Capture Completed Actuals During Post Mortem and
