Working with Subject Matter Experts: Getting the Most from Your SMEs

Every project team knows the problem. The subject matter expert whose input is essential to three deliverables simultaneously is also the person with a full operational role and a calendar that cannot be cleared. They are not obstructing the project; they are doing their existing job while the project asks them to do another one. This is one of the most common sources of schedule slippage on projects that have nothing technically wrong with them. The solution is not to escalate louder — it is to redesign how the project team engages its SMEs so that the time they give yields maximum value.

Why SMEs Are Usually the Bottleneck

The bottleneck is structural. SMEs hold knowledge that no one else on the project has, which means certain decisions and validations cannot proceed without them. At the same time, their operational workload is almost never reduced to accommodate project involvement. The project asks them for time; their manager asks them for output; both are legitimate demands, and the project is often the lower-priority item.

A secondary issue is that SMEs are frequently unclear about what they are being asked to contribute. A meeting invitation that says "review session — your input needed" does not give an expert the context to prepare. The first part of every meeting is then spent on context that could have been provided in advance.

Front-Load SME Engagement

The single most effective adjustment a project team can make is to engage SMEs earlier and more intensively at the start, rather than pulling them in iteratively as each deliverable reaches a gate. Early engagement serves two purposes: it gives SMEs the opportunity to shape the direction of the work before significant effort has been invested in a direction they may need to correct, and it surfaces constraints and dependencies that would otherwise emerge as surprises later in the schedule.

A structured kickoff that maps out what each SME needs to contribute, and when, is far more respectful of their time than an ad hoc series of individual requests. It also allows SMEs to plan their own availability.

Prepare Structured Questions

Generic discussion rarely produces the information a project team needs from an SME. Structured questions — prepared and circulated in advance — change the dynamic entirely. The SME arrives knowing what they are being asked, has had time to think, and can give a more considered and complete answer. The project team gets targeted input rather than a general conversation from which they must later extract the relevant content.

Format matters too. Questions requiring a short specific answer, a decision between two options, or a validation of a draft are far easier for a busy expert than open-ended requests for their views. Wherever possible, ask the SME to react to something rather than produce something — a draft, a framework, a structured template — rather than generating content from scratch.

Use Asynchronous Review

Not every SME contribution requires a meeting. Review and validation tasks — checking a document for accuracy, confirming that a process description reflects current practice, approving a set of assumptions — can often be handled asynchronously if the request is specific and the timeline is clear. A well-constructed async review request, with a precise scope, a deadline, and a clear explanation of what happens if no feedback is received, is often more respectful of an expert's time than scheduling yet another hour on their calendar.

Track and Acknowledge Their Contribution

SME time is a contribution, not an entitlement. Project managers who explicitly track the time SMEs give to the project, acknowledge it in project communications, and ensure it is visible to their managers are doing two things simultaneously: being professionally courteous and creating accountability. An SME whose manager can see that they have contributed 18 hours to the project over the past month is better positioned to have that contribution recognised — and more likely to prioritise future project requests — than one whose involvement is invisible.

When SME Unavailability Is Blocking the Project

When SME unavailability becomes an active schedule risk, the project manager must act. The first step is to make the dependency visible: document which deliverables are blocked, by how long, and what the downstream impact is. A concrete impact statement is far more persuasive than a general complaint about availability.

The second step is to escalate appropriately. The SME's manager is the right person to engage — not as an adversary but as someone who may not be aware of the project's dependency on their team member's time. Where unavailability is genuinely unavoidable, identify alternatives: a delegate with partial knowledge, a documented source that substitutes for the SME's input, or a scope adjustment that removes the dependency until they are available.
