Resource Basis of Estimates (Example)
A detailed worked handbook example for resource basis of estimates (example), grounded in the supplied KEVOS project-management source material.
What this artefact controls
Resource Basis of Estimates (Example) should be treated as a decision instrument, not as paperwork completed for its own sake. Its practical value comes from making the underlying decision, evidence, ownership and review cycle visible. In this handbook, the supplied source structure is retained as the factual basis while the surrounding guidance explains how to complete, review and maintain it in day-to-day project delivery.
The source set repeatedly links project documents to broader control relationships: scope creates the work to be scheduled and costed; resources execute that work; stakeholders influence acceptance and change; risk captures uncertainty; quality establishes evidence of conformance; and performance information explains whether the project is still moving toward its intended outcome. Resource Basis of Estimates (Example) belongs in that integrated system. It should therefore use identifiers and terminology consistent with adjacent project records so that a reviewer can trace a decision across documents without relying on memory.
Before filling any field, write one sentence describing the decision or control action the completed artefact must support. Then identify the accountable owner, contributors, reviewers, approval authority and next review trigger. This prevents a common failure in project documentation: every box is filled, but nobody can explain what decision the document enables or who must act when conditions change.
How the information fits together
This visual is an HTML/CSS interpretation for the KEVOS article reader. It conveys the decision structure without embedding the supplied source artwork as a screenshot.
Complete the template with traceable information
The following field map is extracted from the supplied blank or completed source document where text was available. Wording has been normalised for web readability, but the source structure remains the basis. Where a field is not applicable, record why rather than silently leaving a potentially important control blank.
| Source field / section | What to record | Review test |
|---|---|---|
| RESOURCE BASIS OF ESTIMATES | Record the minimum evidence needed for resource basis of estimates to support the define the people, equipment, facilities, services and governance needed to execute the work without hidden capacity constraints. | The entry is specific, traceable and reviewable. |
| Approach | Record the minimum evidence needed for approach to support the define the people, equipment, facilities, services and governance needed to execute the work without hidden capacity constraints. | The entry is specific, traceable and reviewable. |
| Estimating Methods Used | Record the minimum evidence needed for estimating methods used to support the define the people, equipment, facilities, services and governance needed to execute the work without hidden capacity constraints. | The entry is specific, traceable and reviewable. |
| Source of Information | Record the minimum evidence needed for source of information to support the define the people, equipment, facilities, services and governance needed to execute the work without hidden capacity constraints. | The entry is specific, traceable and reviewable. |
| Assumptions | State why the condition matters, who will validate it and what happens if it proves false or changes. | The entry is specific, traceable and reviewable. |
| Constraints | State why the condition matters, who will validate it and what happens if it proves false or changes. | The entry is specific, traceable and reviewable. |
| Range & Confidence | Assign a unique, stable identifier that can be referenced from reports, changes, risks, requirements or evidence. | The entry is specific, traceable and reviewable. |
| Risks & Reserves | Link uncertainty to an objective, record the response and make the trigger observable enough to prompt timely action. | The entry is specific, traceable and reviewable. |

What the uploaded example demonstrates
The source set uses a recurring worked project — Mary’s Consulting and its new company website — to show how project artefacts connect. The examples are useful because the same scope, team, costs, risks, stakeholders and milestones recur across multiple forms, allowing the reader to see how one project decision propagates through the documentation system. Any numerical value below is a source example or a calculation explicitly identified as such; it should not be treated as a universal project standard.
- Project Date May 18,
- Title: Prepared: 2026
- Bottom-up: Each activity's resource needs estimated individually, then aggregated to the work-package and project
- Analogous: Resource counts validated against two prior projects (brand refresh 2024; marketing-site refresh 2023).
- Parametric: Used for content production (hours-per-page, hours-per-case-study) and imagery ($/image × number of
- Expert judgment: Team leads (Bob, Bill, Christine) consulted on skill-level requirements for their respective domains.
- • Core team allocated at planned percentages through project close (PM 50%, Bob 75% during build, Bill 75% during
- design, Christine 60% throughout).
Step-by-step workflow
For controlled project records, the final step is not “save the file”. The final step is to make the current approved state discoverable, communicate the decision to affected people and define the next review trigger. That trigger may be a phase gate, threshold breach, approved change, new stakeholder, supplier event, forecast movement, risk trigger or a scheduled review date.
Review checklist before approval or use
- Requirements distinguish role, quantity and timing.
- Critical competencies are named rather than implied by job title.
- There is one accountable role for each key decision.
- Resource calendars agree with the schedule.
- External services include lead time and procurement dependency.
- Team expectations include escalation, decision and communication rules.
Run the review from the perspective of a competent person who did not attend the drafting meeting. If they cannot reconstruct the basis, current state and required next action from the record and its cited evidence, the artefact is not yet controlled enough for a material decision.
Common mistakes and recovery actions
Listing names without defining the required capability.
Recovery: return to the approved objective or baseline, identify the missing evidence or decision owner, and record the corrective action before proceeding.
Assuming nominal availability equals usable capacity.
Recovery: return to the approved objective or baseline, identify the missing evidence or decision owner, and record the corrective action before proceeding.
Giving several people accountability for the same outcome.
Recovery: return to the approved objective or baseline, identify the missing evidence or decision owner, and record the corrective action before proceeding.
Ignoring equipment, facilities or digital environments.
Recovery: return to the approved objective or baseline, identify the missing evidence or decision owner, and record the corrective action before proceeding.
Treating over-allocation as a scheduling problem only.
Recovery: return to the approved objective or baseline, identify the missing evidence or decision owner, and record the corrective action before proceeding.
Keep the document alive after first approval
A project artefact is only useful while its status is known. Give it a unique identifier, version, owner, approval state and effective date. Define what types of change require reapproval and what updates can be made administratively. Retain superseded versions when the record is needed to explain a historical decision, claim, audit, acceptance or lesson.
Use the document in reviews by focusing on exceptions and decisions rather than reading every field aloud. Ask what has changed since the last review, what assumption has been invalidated, what threshold has been crossed, which decision is now due and which action remains without an owner. This converts the artefact from static documentation into a control mechanism.
At hand-off, confirm that downstream users can interpret the identifiers, units, assumptions and status values without relying on the original author. For project close-out, make sure unresolved items have an operational owner and a clear retention location. A closed project should not leave behind orphaned risks, undocumented support obligations, unverified benefits or ambiguous acceptance evidence.
Source basis and limitations
This page is an original KEVOS handbook synthesis grounded in the uploaded source files. It intentionally paraphrases and restructures the material for practical application rather than reproducing the source documents as images. Where the source contains an illustrative project value, that value remains an example. Where a required blank source was absent, the limitation is stated explicitly rather than silently inventing a missing form.
