The method
- Describe the deliverable with observable criteria: quantity, format, location, schedule and acceptance. Replace “a complete solution” with a list of outcomes you can actually check.
- State necessary information and scope boundaries. Ask for supplies, installation, travel, options and follow-up to be identified when relevant to the project.
- Put replies into one comparison grid. A missing row means “to clarify”, not “included free”. Resolve differences before comparing totals or making a commitment.
Fictional worked example
For a fictional seminar, the brief requests a room, audiovisual equipment and participant reception. Quotation A includes setup; B prices equipment hire only. Ask about the missing item before declaring B cheaper: the scopes are not yet equivalent.
The record to keep
Keep the dated brief, the version sent, replies and clarified points. This avoids comparing an old quotation with a revised request.
Your record, step by step
For your own situation, record the following information. Check a field when it is documented; missing information still needs verification. The boxes are a reminder within this page.
This checklist does not validate your project. No entries are sent or saved.
Fictional worked case. A fictional brief concerns scanning 200 pages. Two proposals look similar until their scope is compared.
| Element | Observation in the case | Interpretation or next check |
|---|---|---|
| Deliverable | A: images; B: PDF with recognised text | The delivered files are different |
| Preparation | A assumes pages are already separated | Specify who prepares and returns the documents |
| Checking | A omits review; B describes a sample | Ask which checks and error corrections are included |
| Revision | Only one proposal includes a correction round | Clarify number, deadline and scope of revisions |
What this method can establish
The grid structures a request and comparison. It is not legal advice about a quotation, a quality guarantee or contract validation.
Useful questions before you start
How should an option missing from a quotation be treated?
Mark it as unspecified. Request a written answer against the same brief; a missing line means neither free nor included.
