It should not be an open-ended period of free implementation. ## Key takeaways - Choose one decision the evaluation can resolve. - Set prerequisites and an owner for each one. - Translate the workflow into acceptance evidence. - The pilot should pause if an incorrect targeting rule can expose the wrong functionality cannot be handled within the agreed test conditions. --- This field guide uses an engineering team releasing changes incrementally as its working context. The buying conversation involves the engineering platform lead, while the software engineer needs to release changes gradually with clear control and rollback. Adapt the scope when those roles, dependencies or operating conditions differ. ## Choose one decision the evaluation can resolve A proof of value should answer a specific question about whether an engineering team releasing changes incrementally can release changes gradually with clear control and rollback under realistic constraints. It should not be an open-ended period of free implementation. Write the question, the participants, the allowed data and the decision date before connecting systems. The engineering platform lead should agree that the selected question matters enough to influence the purchase. ## Set prerequisites and an owner for each one List the required access to application SDK, identity context and observability, the sample records, user availability and any approval needed to run the exercise. Missing prerequisites should pause the clock rather than quietly shrinking the evaluation. A salesperson should not compensate by performing every user task and then describing the account as activated. Assign a customer owner and a vendor owner so blocked work has a clear route for resolution. ## Translate the workflow into acceptance evidence Use evaluate a test flag for a defined segment and exercise rollback as the first observable checkpoint and a controlled rollout with evaluation context, fallback and stale-flag cleanup as the evidence exercise. Describe what will be inspected, by whom and against which baseline. Prefer an artifact or a reproducible action over an opinion such as "the team liked it." Some requirements may be binary, while others require a measured range or a qualitative review. Keep these different types of evidence visible instead of combining them into one unexplained score. ## Include an exception and a realistic support boundary The objection "Flags will create complexity and inconsistent user experiences" should influence the test design. Include a relevant exception rather than testing only the easiest path. Record how much vendor assistance the exercise required, because that effort affects the feasibility of rollout. A trial completed by a specialist on behalf of the customer is evidence of specialist capability, not independent customer adoption. Decide whether the required support belongs in the commercial offer. ## Use a baseline and avoid invented savings If the evaluation measures time or error reduction, define comparable work before and after the change. Record task complexity, participant experience and interruptions. Do not annualize one unusually favorable observation without explaining the assumptions. A sample exercise can reveal a promising mechanism while remaining too small to establish a reliable business-wide effect. Show the arithmetic, the uncertainty and the additional evidence needed for an investment decision. ## End with one of three explicit outcomes Proceed when the agreed evidence is present and the unresolved risks are acceptable. Extend only when a named missing test could change the decision and there is a bounded plan to complete it. Stop when the workflow is unsuitable or the implementation burden is unacceptable. The longer-term adoption condition remains whether teams manage flag ownership, exposure and retirement consistently. Preserve the evaluation record so onboarding does not start from a sales summary that omits the difficult parts. ## Category-specific review A feature flag has targeting context, a default behavior and a lifecycle after rollout. Flags can become difficult to reason about when ownership and retirement are unclear. Ask how the team handles missing context and how it knows a flag is no longer needed. Test a targeted user, a non-targeted user and an unavailable evaluation dependency. Inspect fallback and rollback behavior in a permitted environment. A successful rollout demonstration should also explain who removes stale configuration after the decision is complete. ## Worked situation A sample evaluation asks five authorized users to complete the agreed workflow. Four can perform it with the planned support; one is blocked by access to application SDK, identity context and observability. Report four completions, the blocked dependency and the support provided. Do not remove the blocked user to report a perfect pass rate. The decision is whether that dependency can be resolved within the intended rollout, not whether the dashboard can display an attractive percentage. The acceptance record should preserve both evaluate a test flag for a defined segment and exercise rollback and the exception. ## Working worksheet | Working item | Category-specific starting point | Question to resolve | | --- | --- | --- | | Decision | release changes gradually with clear control and rollback | Which purchase question can this test resolve? | | Prerequisite | application SDK, identity context and observability | Who grants access and by when? | | First checkpoint | evaluate a test flag for a defined segment and exercise rollback | What artifact demonstrates completion? | | Exception test | Flags will create complexity and inconsistent user experiences | What failure case must be exercised? | | Adoption boundary | teams manage flag ownership, exposure and retirement consistently | What remains to verify after the pilot? | Add your evidence, owner and next action to each row. Read the [worksheet instructions](/resources/#using-worksheets) before completing the file. ## Run the review with the people who do the work Bring the software engineer into the review of a controlled rollout with evaluation context, fallback and stale-flag cleanup. Ask them to identify the input they would actually have, the exception they expect to encounter and the person who receives the output. Then ask the engineering platform lead which unresolved issue could change the decision. Keep the two answers separate until the team understands whether the obstacle is workflow fit, implementation readiness or commercial priority. Record any dependency on application SDK, identity context and observability beside the affected worksheet row. A dependency should have an owner and an observable completion condition. If it changes the scope of the offer, revise the public description before the next campaign. This prevents a useful planning exercise from turning into a promise the delivery team cannot meet. ## When to change the plan The pilot should pause if an incorrect targeting rule can expose the wrong functionality cannot be handled within the agreed test conditions. If new evidence changes the audience, required workflow or acceptance conditions, update the brief and explain why. Compare later results against the version of the plan that was actually used. ## Continue with the next decision Use the [customer onboarding guide](/industries/feature-management/onboarding/) when that is the next unresolved task, or return to the [feature flag software marketing overview](/industries/feature-management/) to choose a different route. The [b2b saas marketing hub](/b2b-saas-marketing/) provides the broader method. ## Reference and scope The [primary category reference](https://launchdarkly.com/docs/) is a starting point for checking product terminology and current capabilities. This page provides an original planning framework. It does not imply a vendor endorsement, firsthand product test, original market survey or guaranteed commercial result. ## Frequently asked questions ### Where should proof of value for feature flag software start? Run a bounded evaluation of feature flag software with agreed inputs, success criteria and a clear stop decision. Confirm the customer situation and the evidence needed for the next decision before selecting a channel, format or tool. ### What category-specific concern should the team investigate? The concern "Flags will create complexity and inconsistent user experiences" needs an observable test or a clear limitation. Also account for the dependency on application SDK, identity context and observability; do not assume it is already resolved. ### What does the worksheet include? It contains the working items and category-specific starting points shown on this page. Add your own evidence, owner, status and next review decision. The examples are constructed, not reported results or industry benchmarks. ### How does this connect to customer value? The customer needs to release changes gradually with clear control and rollback. A meaningful first checkpoint is to evaluate a test flag for a defined segment and exercise rollback; the ongoing condition is that teams manage flag ownership, exposure and retirement consistently. Choose the stage appropriate to this piece of work rather than combining all three into one metric.
