Choosing a Claude Implementation Partner: Evidence to Ask For

Selecting a Claude implementation partner is not a branding exercise. You need to establish three things before committing meaningful scope: what designation the organisation can substantiate, whether its references show relevant delivery rather than general AI enthusiasm, and who will be accountable when the implementation meets real operating conditions.

This checklist is designed for mid-market leaders comparing vendors or narrowing a shortlist. It does not determine whether a particular vendor is suitable, and a designation alone cannot prove delivery quality. Use the items to gather evidence, expose gaps and decide what work—if any—you are comfortable assigning. Record the source and date for each claim; do not rely on a sales presentation as the only evidence.

For a broader method to compare vendors across categories, use A Vendor-Scoring Framework for AI and Software Partners. This checklist concentrates on evidence specific to a Claude implementation and the people responsible for operating it.

1. Define the decision before reviewing claims

A vendor can be credible for a bounded prototype and still be an unsuitable owner for a production workflow. Before asking for credentials or references, write down what you are buying. Otherwise, sales evidence will tend to answer the question the vendor is best prepared to answer, not the decision your organisation needs to make.

• Name the business workflow and the intended boundary. Describe the user, the input, the expected output and what happens next. For example: an employee submits a supplier-change request; the system extracts proposed changes and drafts a review summary; a designated employee decides whether to update the supplier record. This is more useful than a broad request to implement Claude because it makes relevant experience identifiable.

• Separate the first delivery from the eventual ambition. Mark what must be included in the first release and what is a later possibility. A project might begin with summarising support cases for human review, while automated case updates remain explicitly out of scope. Ask the vendor to respond to the first boundary, not to an expansive roadmap that makes every capability sound necessary.

• Identify the decision your organisation must make now. Are you choosing a discovery provider, a prototype team, an integration partner, or an organisation expected to support a production service? These are different commitments. A vendor may be a strong choice for one and an unproven choice for another. Make the intended decision and its duration visible in the request.

• List the evidence that could change your mind. Decide in advance what would count as a relevant reference, a verified designation, and a credible operating plan. Examples include a reference for a comparable workflow, a named technical lead who will actually participate, and a written route for investigating failures. This prevents the team from substituting familiarity or polished materials for decision-relevant proof.

• Set a boundary for unresolved evidence. Decide whether a missing reference means a smaller initial scope, a paid discovery phase, a further diligence step, or no engagement. A gap need not automatically disqualify a vendor, but it should have a consequence. If the same gap is treated as irrelevant after a persuasive meeting, the checklist is not governing the decision.

2. Verify the designation precisely

Use the word partner carefully. A company’s marketing label, an individual employee’s credential and an organisation’s verified relationship are not interchangeable evidence. The exact designation also matters: a claim about a particular tier should be checked as that claim, rather than accepted because the vendor can show a different credential or a general relationship.

Anthropic describes its Services Partner Program as having a registered entry, with partnership beginning at Select, followed by Preferred and Global Premier tiers. Individual certification is distinct from an organisation’s partner status. Confirm the current listing and the claimed level directly rather than inferring one from the other. Anthropic’s partner information is the primary reference for that distinction.

• Ask for the exact legal or trading entity making the claim. Record the name on the proposal and the name associated with the claimed designation. If those differ, ask the vendor to explain the relationship and provide evidence that connects the entities. A group company, subcontractor, brand or individual may be involved; do not silently assume that a claim attached to one automatically applies to another.

• Ask the vendor to state the exact status and tier in writing. Capture the wording, the date it was checked and the entity to which it applies. Avoid translating broad phrases such as ecosystem participant or certified team into a stronger organisational claim. When the stated category is not clear, ask the vendor to clarify it rather than choosing the interpretation most favourable to the sale.

• Check the claimed organisation-level status against the primary source. Match the entity and category, not merely a logo, slide or employee profile. If the available public information does not resolve the claim, request current supporting evidence and a way to verify it. Record an unresolved claim as unresolved; do not convert an explanation from the sales team into independent confirmation.

• Separate company status from individual credentials. Ask which named people hold relevant certifications and what work they will perform. An individual credential can be useful evidence of that person’s learning, but it does not by itself establish organisational partner status, delivery experience or ongoing accountability. Conversely, a company-level status does not prove that the proposed project team includes the people who earned it.

• Tie the claim to the proposed team and contract. Ask whether the people presented during selection will be assigned to the work, and identify any expected substitutions or subcontracting. The practical question is not only whether a vendor can substantiate a designation; it is whether the named team and accountable entity will deliver the scope you are evaluating.

The designation is one input, not a shortcut around references. If the vendor’s status is verified but the proposed team has no relevant delivery evidence, the next step is still to assess the experience gap. If the team appears capable but the designation claim cannot be substantiated, assess the proposal on the evidence that is available and describe the claim accurately in your records.

3. Test references for comparable delivery

A reference is useful when it helps you predict how the vendor will handle work resembling yours. A list of logos, a general endorsement or a demonstration of a polished interface does not reveal the delivery conditions behind the result. Ask for a conversation with someone able to discuss the scope, decisions, handoffs and difficulties—not only the vendor’s account of the project.

• Request references for work with a comparable operational shape. Compare the workflow, users, source information, downstream action and need for human review. The industry may differ while the operating pattern is similar; two projects in the same industry may have little in common if one was a one-off demonstration and the other had to fit an established process.

• Ask what the vendor actually delivered. Have the reference distinguish the vendor’s work from the client’s work, other suppliers’ work and any pre-existing system. A reference who can explain the vendor’s role in discovery, integration, evaluation, deployment or support gives you more useful evidence than a broad statement that the project used Claude.

• Ask who from the proposed team participated. Record the people and roles, and compare them with the people presented to you. A company’s past project is not automatically evidence for a new team. If the reference describes a specialist who will not join your engagement, ask what experience the assigned team can demonstrate instead.

• Ask how the work moved from an idea to a bounded release. Invite the reference to describe what was included, what was excluded, and how changes in scope were handled. Listen for evidence that the team made specific decisions about workflow boundaries and acceptance, not simply that it built a demo. A disciplined change in scope can be a stronger signal than a claim that every initial assumption was right.

• Ask what was difficult after the first successful demonstration. Useful topics include inconsistent inputs, review workload, integration handoffs, changes to the surrounding process, and deciding when a result needed escalation. The point is not to demand a flawless story. A reference who can explain a difficulty, the team’s response and the remaining limitation can help you assess the vendor’s judgement.

• Ask what happened when the system produced an unsuitable result. Find out how the problem was noticed, who could intervene, what happened to the affected work, and whether the team changed the workflow or merely adjusted a prompt. A reference should not have to disclose confidential content. They can still describe the failure path and the kind of evidence used to decide what to change.

• Ask how success was judged in the client’s actual workflow. Separate a favourable model output from a useful business outcome. Did the client examine the work completed, the review required, exceptions, or user adoption? Do not ask the reference to provide a universal performance number. Ask what their team observed, how it was defined and what was outside the measurement.

• Ask whether the reference would hire the same team for the next phase. Follow up with what they would keep, change or narrow. This is more informative than a simple satisfaction score because it invites a concrete account of fit. Treat the answer as one data point, not a transferable guarantee: your process, constraints, staff and operating context may differ.

A vendor may be unable to connect you directly with a particular customer. That does not prove poor delivery, but it changes the evidence available. Ask whether the vendor can provide an anonymised walkthrough of a comparable engagement, a redacted delivery artefact, or another reference suited to the confidentiality constraint. Clearly label what you have independently heard and what remains vendor-reported.

For broader warning signs in supplier selection, consult Red Flags When Hiring an AI or Software Development Partner. Use it to sharpen follow-up questions, not to treat one awkward answer as an automatic verdict without context.

4. Confirm that accountability survives delivery

A credible proposal names more than a person who will lead workshops. It explains who will make technical decisions, who will investigate a failure, what the client team must provide, and who remains responsible for each handoff. These are not administrative details to postpone until launch. They shape whether a problem can be contained and understood once real work reaches the system.

• Name the accountable delivery lead and the time they will contribute. Ask who is responsible for coordinating the work and resolving delivery decisions, and whether that person will remain involved beyond initial discovery. A senior name on a proposal is weak evidence if most decisions will be made by an unnamed team with no defined escalation route.

• Name the technical owner for the implementation boundary. Identify who will take responsibility for the application or workflow components the vendor is contracted to build. Clarify what is outside that boundary, such as a client-owned record system or an external service. The aim is not to assign every future problem to one supplier; it is to prevent a gap where each party assumes another party owns the failed handoff.

• Ask who investigates a reported failure and what they need to begin. Establish the initial reporting route, the information the client should preserve, and who decides whether to pause or route affected work differently. A useful answer describes an operational process, not an absolute promise that no failure will occur or that every report will receive a particular resolution.

• Clarify responsibility for changes after acceptance. Ask how defects, requested workflow changes and new requirements will be distinguished and handled. Agree what information accompanies a request and who can decide its priority. Without this distinction, routine corrections may be treated as new scope, while new scope may be allowed to slip into delivery without a deliberate decision.

• Make handoffs explicit. Identify what the vendor will leave with the client at the end of each phase, who receives it, and what the client must be able to do next. Depending on the agreed scope, this could include a workflow description, configuration information, test cases or operating instructions. Do not assume a deliverable exists because it appears in a presentation; make it part of the working plan.

• Confirm the escalation route across organisations. Record who can raise an issue, who receives it, and who can make a decision when the vendor and client disagree about severity or next steps. The route should still make sense if the day-to-day contact is unavailable. A single named person without a backup or decision path is a brittle operating arrangement.

• Ask how the vendor will report uncertainty and unresolved issues. Establish where open decisions, known limitations and outstanding work will be recorded, and how they will affect release readiness. You want the team to make uncertainty visible early enough for your organisation to choose a narrower scope, provide missing information or delay a handoff—not discover a material assumption after users depend on it.

Use the following matrix during selection and revise it before signing. The entries are prompts, not a claim that every role belongs to one supplier. Name the actual organisation or person for each responsibility, including client-side responsibilities and unresolved items.

Responsibility	Evidence to request	Owner to record	Boundary to clarify
Workflow definition	Agreed workflow description and exclusions	Client process owner; vendor delivery lead	Which cases are in scope and which are routed elsewhere
Implementation decisions	Named technical lead and decision log	Vendor technical owner	Components the vendor builds versus client-owned systems
Review and exception handling	Defined review point and escalation path	Client operations lead	Who can stop, return or reassign affected work
Failure investigation	Reporting route and information to preserve	Named vendor contact and client contact	Who investigates each component and who coordinates across them
Release acceptance	Written acceptance criteria and unresolved-issue list	Named client decision-maker	What blocks release and what may be deferred
Ongoing changes	Change-request route and agreed support boundary	Named owner on each side	Defect, changed requirement or new scope

5. Evaluate the operating plan through a failure timeline

Plans are easiest to assess when you ask what happens in sequence after a problem appears. Consider a hypothetical supplier-change workflow. A user submits a request containing a supplier name, a proposed bank-detail change and a supporting document. The system prepares a summary for an employee, who decides whether to update the supplier record. The example is illustrative; it does not describe a particular vendor or deployment.

Imagine that, on a busy Monday, the summary associates a bank detail from an older attachment with the current request. The issue is noticed during employee review before the record is changed. Ask the vendor to walk through the next steps: how the reviewer marks or routes the item, what information is retained for investigation, which person on each side is notified, and who decides whether similar requests should be held while the cause is understood.

Now change the timeline. The reviewer does not notice the mismatch and the record is updated. Ask how the business would identify which request was affected, who can coordinate correction in the client-owned record system, and who investigates the implementation’s role. The partner should be able to distinguish its contracted responsibilities from the client’s operational decisions without leaving the client to reconstruct the entire chain unaided.

The scenario also tests whether the proposal treats review as a meaningful control or as a label. If the employee is expected to validate a result, ask what information makes that review possible and how an uncertain or incomplete case is presented. If the vendor cannot explain who acts when the intended reviewer is unavailable, the plan may have a people-and-process gap even if the technical proposal sounds complete.

• Trace one ordinary case from input to final action. Ask the vendor to mark where information enters, where the system contributes, where a person decides, and where the result becomes part of the existing process. Compare this path with the one your staff actually follow. Differences often expose hidden manual work or an unowned transition before implementation begins.

• Trace one exception from detection to disposition. Use a missing document, conflicting values or an unclear request. Find out who sees the exception, who decides what happens next and how the work returns to a known state. A design that describes the normal path but leaves exceptions to informal judgement is incomplete for operational use.

• Ask what evidence is retained for investigating a disputed result. Agree what can be reviewed, by whom and for what purpose within the proposed arrangement. Do not accept a vague assurance that issues can be debugged; ask the vendor to identify the practical information it expects to use and the information it does not expect to collect.

• Ask what happens if a key vendor contact is unavailable. Identify the alternate contact and the route for a time-sensitive issue. A process that depends on reaching one individual may work during a demonstration and fail during ordinary leave, staff turnover or competing priorities. Request a realistic escalation path, not a promise of unlimited availability.

• Ask how a suspected recurring issue changes the workflow. Clarify who can decide to hold a category of work, narrow the affected scope or return to the previous process while the issue is investigated. The proposal should describe decision rights and coordination, not imply that a technical adjustment alone resolves every operational consequence.

6. Turn evidence into a bounded award decision

A selection does not have to be all-or-nothing. If a vendor has strong evidence for discovery but limited production references, you can consider a narrower first commitment with explicit outputs and a separate decision before expansion. If its designation is verified but operational ownership is unclear, resolve the ownership gap before assigning live workflow responsibility. Bounded scope is useful only when it genuinely limits exposure and creates evidence for the next decision.

Use this flow to classify the next action. A no at an evidence gate is not always a permanent rejection; it means the claim or readiness has not been established for the proposed scope.

accTitle: Evidence gates for a bounded partner decision accDescr: Define the proposed scope, verify the designation, assess relevant delivery evidence, then confirm an operational owner. Missing evidence leads to an unverified record or a limited or deferred award; complete evidence supports a bounded award decision.

The diagram distinguishes three different conditions. An unverified designation should be recorded accurately; it is not repaired by a good reference. Relevant delivery evidence concerns the team and work, not a status label. Operational ownership asks whether the proposed engagement has named responsibility for the work it will affect. Passing all three gates supports consideration of a bounded award, not an assumption that every future phase is already approved.

• Write down the scope you are actually prepared to award. State the workflow, user group, boundary, phase and deliverables. If the evidence supports only discovery or a limited prototype, say that directly. Do not let a preliminary approval be described later as acceptance of a production rollout that was never assessed.

• Attach each material claim to its evidence. For designation, record the primary source or the unresolved status. For references, record what the reference personally confirmed. For accountability, record the proposal, named role or agreed responsibility. Distinguish independently checked information from vendor-provided material so that confidence does not increase simply because the same claim appears in several documents.

• Record the gap, its consequence and the person who can close it. For example, a missing comparable reference might lead to a smaller first phase and a decision gate before expansion. An unclear failure route might block work touching live operations until named contacts and responsibilities are agreed. A gap without an owner or consequence is likely to survive into delivery.

• Set an explicit decision point before any scope expansion. Specify what evidence must exist before the next phase is considered: completed deliverables, unresolved issues, referenceable outcomes where available, and confirmation that the operating responsibilities remain workable. Treat this as a new decision based on observed work, not as a foregone conclusion written into a roadmap.

• Keep the record usable by people who were not in the sales meetings. Summarise the decision, its limits, the evidence checked, open questions and the next review point. A concise record helps a new executive, procurement colleague or delivery lead understand why the vendor was selected and what was deliberately not assumed.

7. Work through a hypothetical selection

Consider a fictional North American distributor choosing a partner for an internal supplier-change review workflow. The operations team receives requests through an existing process. It wants a system to prepare a structured summary for employee review, not to make or apply supplier-record changes automatically. The company is comparing two vendors. The following example is invented to show how the checklist can affect a decision; it is not a report of a real evaluation or result.

Vendor A provides a current, verifiable organisational designation at the level it claims. It offers a reference for work involving a different industry but a similar document-review workflow. The reference describes the vendor’s role and explains how exceptions were routed. However, the vendor proposes an account lead who was not involved in that reference project, and its initial plan leaves post-launch issue investigation to a general support contact without defining the client-side handoff.

Vendor B cannot substantiate the organisational designation it uses in a slide, although it identifies an individual credential held by one proposed team member. It has a reference involving an adjacent workflow and names the technical lead who would participate. Its draft plan identifies an owner on each side for investigating a disputed summary and a route for holding affected requests. This does not automatically make Vendor B the better choice: its designation claim needs accurate treatment, and the reference still needs to be tested for scope and relevance.

A disciplined decision would not collapse these facts into one score. The buyer would record Vendor A’s verified status, then assess whether the reference and assigned team support the intended work. It would ask for the missing operational route to be defined before awarding any scope that depends on it. For Vendor B, it would correct the designation description in the record, speak with the reference, and assess the named team and operating plan on their own merits. Neither vendor should receive credit for evidence it has not supplied.

Suppose the organisation then chooses a bounded first phase with Vendor A, conditional on named investigation contacts and an agreed exception path. That decision is defensible only if those conditions are written into the work plan and are resolved before the relevant work begins. If Vendor A declines to name an accountable owner, the decision should change: use a narrower discovery scope, continue the comparison, or defer the award. The status claim does not compensate for a missing responsibility.

Now consider the counterexample: a vendor presents a polished demonstration, several recognisable customer logos and a senior advisor with an impressive profile. It cannot identify which proposed team members delivered comparable work, cannot arrange a reference or provide an alternative account of the delivery, and says operational ownership will be settled after kickoff. The problem is not that every vendor must disclose confidential client details or provide the same artefacts. The problem is that the central claims remain untestable while the proposed commitment already assumes delivery readiness.

In that case, a reasonable next step is to request a narrower, clearly defined engagement that generates evidence without quietly placing the unverified workflow into routine use. If the vendor cannot define even that boundary or name the person responsible for its work, declining is more defensible than treating the demonstration as a substitute for accountability. The right outcome depends on your scope and tolerance for unresolved evidence, but the decision should reflect the gaps rather than conceal them.

8. Diagnose common evidence failures

A reference call can sound positive and still fail to answer your question. Perhaps the reference knows the vendor’s sales team but not its delivery team, or the project ended before operational handoff. Record what the person can actually attest to. Ask for another contact with delivery knowledge, a different reference, or a more limited claim. Do not quote a general endorsement internally as proof of a specific implementation capability.

A designation can also be real but irrelevant to the people and work being proposed. If the vendor relies on its status while presenting a team with no demonstrated connection to that capability, ask who will do the work and how the proposed lead will guide it. The response may reveal a credible staffing plan; it may instead confirm that the designation is serving as a proxy for evidence the vendor has not provided.

Another failure occurs when the vendor and buyer use the word support to mean different things. The vendor may mean answering questions about its deliverables, while the buyer assumes that the vendor will coordinate investigation across the workflow. Write down the triggering event, initial contact, information to preserve, decision-maker and boundary of each party’s responsibility. If those details are unresolved, do not treat a broad support statement as a completed operating plan.

• Challenge evidence that is impressive but not attributable. Ask who did what, when, and on which part of the work. If the answer points to the company generally, request a more precise account. Attribution helps distinguish organisation-wide reputation from relevant experience held by the actual delivery team.

• Notice when the reference describes a different stage of maturity. A prototype reference may help assess discovery and early iteration, but not establish production operations. A mature service may provide relevant operational evidence while differing from your scope in other ways. Record the match and the gap instead of labelling a reference simply relevant or irrelevant.

• Revisit conclusions when proposed staffing changes. If the lead, technical owner or delivery organisation changes, compare the revised team with the evidence used to select the vendor. Ask what continuity remains and what new evidence is needed. A selection decision is tied to a proposed delivery arrangement, not permanently attached to a company name.

• Treat unclear answers as questions to resolve, not as proof of misconduct. Vendors may have confidentiality limits or may not have anticipated a practical question. Ask for an acceptable alternative and set a reasonable decision point. If the gap persists, reflect the uncertainty in the scope, terms or award decision instead of making an unsupported accusation.

NIST’s AI Risk Management Framework is a voluntary framework for AI risk management; it is not a certification or a guarantee of outcomes. NIST’s framework overview can inform internal risk conversations, but citing a framework does not replace evidence about this vendor’s team, references or operational responsibilities.

Before you approve the record, check that the status claim is stated no more strongly than the evidence supports, that reference notes distinguish what was heard from what was inferred, and that every material operating responsibility has an owner or an explicit unresolved status. The final decision should say what the vendor is being asked to do now—not what the organisation hopes it might eventually do.

10. Choose the next step that matches the gap

If the main uncertainty is organisational capability to run the selection and delivery decision, consider whether fractional CTO leadership is relevant to your situation. If the question is whether your organisation needs that kind of support for an AI programme, see When to Hire a Fractional CTO for an AI Programme. These are different questions: this checklist is about evidence for a prospective implementation partner, not a recommendation to hire any particular advisory service.

If your remaining decision depends on the full cost of connecting implementation to ongoing operations, An AI Business Case That Includes Integration and Ongoing Operations addresses that separate planning problem. Keep it distinct from partner verification: a credible business case cannot prove a vendor’s designation or delivery record, and strong vendor evidence does not by itself establish that a project should proceed.

The practical standard is straightforward: verify the designation as the specific claim it is, test references against the work and people you are considering, and name responsibility for the operating path before expanding scope. Where evidence is incomplete, record the gap and make the commitment smaller or wait for clarification. That gives your team a decision it can explain later without treating a title, a demonstration or a confident promise as proof of delivery.
