Credibility & Methodology
How Operational Reference develops professional references
Operational decisions are often difficult for a simple reason:
the necessary information exists, but it is scattered across many different places.
A single decision may require information from:
- technical guidance;
- manufacturers;
- operators;
- consultants;
- regulations;
- engineering references;
- academic research;
- procurement documentation;
- operating experience.
These sources are valuable, but they rarely exist as one coherent decision system.
Operational Reference is designed to bridge that gap.
Editorial and calculation checks are in progress. External professional review will follow before publication.

Publisher, Operational Reference
Jose Santos is the founder and publisher of Operational Reference, an independent professional publishing project focused on practical handbooks and decision tools for complex operational choices. His role is to develop the research, editorial framework and decision tools behind each publication. Where specialist technical or operational validation is required, external professional review is a requirement before publication. For OR 001, this review is still pending.
1. Start with the decision
Each title begins with a specific professional decision rather than a broad subject.
For OR 001, the question is not simply:
How does a hotel laundry work?
The relevant questions are more practical:
- How much laundry will the hotel actually produce?
- What happens on peak days?
- How much capacity is required?
- What redundancy is justified?
- What should be done in-house and what should be outsourced?
- What does each option really cost?
- How should competing supplier proposals be compared?
- How should the system be commissioned?
- How should performance be measured afterwards?
The publication is structured around those decisions.
2. Gather and compare relevant sources
Relevant information is collected from a range of professional sources.
These may include:
- technical documentation;
- industry guidance;
- manufacturer information;
- regulations and standards;
- research publications;
- professional associations;
- operational references;
- specialist publications.
Commercial sources are not automatically excluded.
Manufacturer and supplier information can be technically valuable.
However, it is treated as one input rather than as independent proof of a commercial conclusion.
3. Separate facts, assumptions and models
An operational decision often requires assumptions because no universal number applies to every project.
Operational Reference therefore aims to distinguish between:
- externally sourced facts;
- typical ranges;
- project assumptions;
- analytical models;
- professional judgment.
Where a variable materially affects the decision, the preferred approach is to make it visible and testable rather than hide it inside a rule of thumb.
4. Turn information into decision tools
A handbook can explain a problem without helping the reader calculate the answer.
Where appropriate, Operational Reference therefore creates practical tools around the publication.
The planned Professional Edition of OR 001 includes models for:
- workload;
- sizing;
- peak demand;
- redundancy;
- OPL versus outsourcing;
- total cost of ownership;
- PAR;
- linen replacement;
- labour productivity;
- supplier comparison;
- operational performance.
These tools are designed to make assumptions explicit and allow users to test alternatives.
5. Internal quality checks
Before publication, the handbook and Professional Edition are checked for:
- internal consistency;
- calculation errors;
- broken formulas;
- inconsistent units;
- contradictory assumptions;
- handbook-to-workbook differences;
- source traceability for material claims;
- publication defects.
After the publication has been frozen, changes are limited to objective errors and material issues identified through quality checks or professional review.
6. External professional review
Where the subject warrants it, Operational Reference seeks independent external review from professionals with relevant experience.
For OR 001, the intended review combines two different perspectives:
Technical review
Focused on areas such as:
- laundry engineering;
- workload and capacity;
- equipment sizing;
- utilities;
- workflow;
- economics;
- procurement;
- commissioning.
Hotel operations review
Focused on:
- operating realism;
- practical usefulness;
- hotel constraints;
- owner/operator decision-making;
- housekeeping and operational implications.
Reviewers are asked to identify material problems rather than rewrite the publication.
Review findings are classified as Critical, Material or Minor. No Critical issue may remain open at publication.
7. Independence
Operational Reference does not sell editorial influence.
We do not accept payment for:
- inclusion;
- rankings;
- favourable conclusions;
- supplier recommendations.
Commercial relationships, if any, are kept separate from editorial decisions.
8. What Operational Reference does not claim
Operational Reference publications are not:
- project-specific engineering approvals;
- legal opinions;
- regulatory certifications;
- guarantees of project performance;
- substitutes for required licensed professional advice.
Their purpose is to improve the structure and quality of a professional decision.
9. Corrections
Despite careful quality checks and review, errors can occur.
Material corrections identified after publication should be documented and addressed in subsequent digital files or editions where appropriate.
Readers may contact Operational Reference to report a potential technical or factual error.
The standard we are aiming for
A user should be able to understand:
- where an important assumption comes from;
- what variables could change the answer;
- what should be checked before making a decision;
- when specialist advice is still required.
That is the standard against which Operational Reference publications are developed.
