Access specialist judgement when your team needs outside expertise.
CATO connects boards, executives and project sponsors with experienced specialists, and helps them choose the right depth of input: a focused expert call, retained access, a fractional specialist or a scoped project.
Specialist expertise for the decision or work ahead.
The practice gives organisations access to experienced specialists when a question, decision or piece of work needs expertise the team does not hold.
CATO assesses the need, identifies suitable expertise from its curated network and structures the engagement. Specialist input might address a technology or cyber question, a workforce matter, a decision on investment or market entry, or an issue going to the board. Suitable expertise is confirmed for each need during scoping.
Specialist subject-matter expertise
Depth in a particular field, function or sector, applied to the organisation's own situation.
Technical and specialist advice
An informed view on a technical or specialist question before a commitment is made or a direction is set.
Board and executive input
Independent, experienced perspective for a board or leadership team working through a significant decision.
Specialist capability over time
A senior specialist working alongside the team for an agreed period, or specialist expertise within a scoped piece of work.

Problems this practice helps solve.
These needs usually begin with a question the team cannot answer with confidence, or work it does not yet have the capability to carry out.
Expertise the team does not hold
Part of the business now depends on specialist knowledge that does not exist internally, and building that knowledge within the organisation is not yet practical.
A technical question without a confident answer
A specialist or technical issue has surfaced, and the people closest to it are not certain the current view is right.
A board needs an independent view
Directors or executives want experienced, independent input before they commit to a significant decision.
Senior capability needed for a period
The organisation needs a senior specialist for a phase of work or change, but not as a permanent role.
A project needs specialist input
A project has reached a point, such as a design choice or a review stage, that calls for expertise its team does not have.
Unclear which expertise is needed
The problem is clear, but the right kind of specialist, or the right way to engage one, is not.
Four ways to engage specialist expertise.
Choose the arrangement that fits your question, the continuity of support you need and the work to be carried out.
Expert Access
Focused input from an experienced practitioner on a specific question or decision, such as testing a proposal, a technical issue or a matter going to the board.
Advisory Desk
Retained access to a broader bench of expertise, drawn on as questions come up across different topics, without scoping a new engagement each time.
Fractional Specialist Advisory
Sustained input from one senior specialist on an agreed scope and time commitment, building context as the work continues.
Advisory & Delivery
A structured advisory or delivery project, with the work, responsibilities and outputs agreed before it starts.
For a practitioner-led workshop or briefing on a specialist topic, see Executive Labs & Briefings. For expert-led professional education, see CATO Academy.
CATO Fractional Specialist Advisory
Access to one senior specialist for a defined period, giving your team continuity of expertise without hiring full-time.
When it fits
A specialist area sits outside your team's experience, the need will continue for a period, and a permanent senior role would be more than the work requires.
Scope and support
CATO agrees the scope and time commitment with you and identifies a suitable specialist. Support typically includes regular working sessions, input on documents and decisions, and progress reporting.
What you gain
Senior judgement applied consistently to your situation by one specialist who builds context over time, with CATO involved while the work runs.
Compared with Advisory Desk
Fractional Specialist Advisory suits sustained input in one area. If you need a broader bench across different topics as needs arise, Advisory Desk is likely to be the better fit.
Example client situations.
Illustrative examples of how specialist input can be arranged for different needs.
A board is weighing a significant technology investment and wants an experienced, independent view of the proposal before it decides.
Possible route: Expert Access
A growing business expects a run of decisions on technology, workforce and market entry, and wants senior input available as each one arises.
Possible route: Advisory Desk
An organisation needs senior cyber security expertise to guide its team through a period of change, but not a permanent appointment.
Possible route: Fractional Specialist Advisory
A business needs a specialist assessment carried out and the resulting changes put in place across several teams.
Possible route: Advisory & Delivery
A leadership team wants a practitioner-led session on an emerging issue, such as the use of artificial intelligence, before setting its own approach.
Possible route: Executive Labs & Briefings
An organisation wants people in a specialist function to build practical knowledge of their field through structured professional education.
Possible route: CATO Academy
How CATO selects the right expertise.
Expertise is selected for the problem, based on the issue, sector, engagement type, availability and required experience.
Understand the business need
Clarify the question or capability gap, who it affects and what useful input would look like.
Define the scope and required expertise
Agree the depth of input needed and the experience it calls for, from a focused call to support over a period.
Identify and structure the engagement
Propose a suitable practitioner and agree how the work will run, including timing, format and confidentiality terms.
Deliver the work and review outcomes
Stay involved while the work runs and review with you whether the input met the need.
CATO works through a curated network of experienced practitioners. We assess the client's issue, identify suitable expertise, and structure the engagement. If the proposed advisor is not the right fit, CATO can identify another suitable practitioner from the network.
Common questions.
What does CATO's Specialist Advisory & Expert Access practice cover?
The practice gives organisations access to specialist judgement and capability their own team does not hold: subject-matter expertise, technical and specialist advice, and independent input for boards and executives. It can be engaged through a focused expert call, retained access through Advisory Desk, a fractional specialist or a scoped project.
How does CATO find the right specialist without a public directory?
CATO starts with your question or need, then identifies suitable practitioners from its curated network based on the issue, sector, engagement type, availability and required experience. Practitioners are not listed publicly. If the proposed advisor is not the right fit, CATO can identify another suitable practitioner from the network.
When is an expert call enough, and when is a project needed?
An expert call suits a defined question that experienced input can answer or test in a focused session. Where the need involves work being carried out, several workstreams or agreed outputs, a scoped project through Advisory & Delivery is usually the better fit. CATO can help you judge which applies before anything is agreed.
How does Fractional Specialist Advisory differ from Advisory Desk?
Fractional Specialist Advisory gives you continuity from one senior specialist on an agreed scope and time commitment. Advisory Desk gives retained access to a broader bench of expertise, drawn on as needs arise across different topics. If you are unsure which suits your situation, CATO can recommend one during scoping.
Can a specialist support our team for a defined period?
Yes. Through Fractional Specialist Advisory, a senior specialist can work with your team for an agreed period around a defined scope and time commitment. The scope, how you will work together and how progress is reported are agreed before work begins and reviewed as the need changes.
How are confidentiality and the boundaries of an engagement handled?
Each engagement is scoped before work begins, including what the practitioner will cover, how they will work with your team and how information will be handled. Confidentiality is managed in line with the agreed terms of the engagement, and CATO remains involved while the work runs.
