What this resource covers
An estimation worksheet makes reasoning visible. It is not an automatic quotation tool. The quality of its result depends on the quality of scope, task breakdown, capacity, rates, dependencies, and risk information entered.
- Record each deliverable and its acceptance boundary
- Break deliverables into analysis, design, build, review, testing, deployment, and support tasks
- Estimate optimistic, likely, and higher-effort cases where uncertainty matters
- Assign responsible roles and available capacity
- Add direct non-labor costs and identified contingency
- Record exclusions, assumptions, estimate date, and approval status
Information to prepare
Populate the worksheet with deliverables, tasks, roles, effort ranges, dependencies, complexity drivers, review and test work, provider costs, risks, contingency, and explicit assumptions.
- Deliverable and task list
- Role effort assumptions
- Available team hours per period
- Dependencies and milestone constraints
- Approved role rates and direct cost information
- Risk register and contingency rationale
Expected planning outputs
The completed worksheet should calculate transparent effort, schedule and cost ranges while preserving the inputs, confidence, exclusions, and unresolved items behind each number.
- Role effort summary
- Capacity-based duration range
- Labor and direct-cost range
- Assumption and exclusion list
- Estimate review record
Practical example
How it can be applied
A simple planning calculation can use role effort multiplied by approved role rates for labor cost. Calendar duration is then based on task dependencies and available capacity, not total effort alone. Infrastructure, licenses, migration, and contingency are added as separate visible items.
Common mistakes to avoid
- Using formulas before defining deliverables
- Treating all hours as interchangeable across roles
- Ignoring partial availability and sequential work
- Hiding contingency inside task estimates
- Removing assumptions when presenting the final worksheet
FAQ
Common questions
What formulas can the worksheet use?
Common planning relationships include labor cost equals role hours multiplied by approved role rate, and capacity-based duration uses effort, dependencies, and available role capacity. They are not substitutes for scope analysis.
Should contingency be the same for every project?
No. It should reflect identified uncertainty, risk, and estimate maturity rather than a universal percentage.
Can this worksheet produce a contract price?
It supports estimation and review. Commercial terms require approved scope, responsibilities, assumptions, and agreement.
