Make the next improvement easier to deliver.

Reuse creates value when a later project avoids work that would otherwise be necessary, after the cost of adaptation and maintenance is counted. A shared catalog or integration can make the next release easier. It can also become expensive infrastructure that no second team uses. Evaluate both possibilities before funding the shared version.

A reliable customer record, a maintained integration or an evaluation dataset may serve more than one workflow. List the consumers before deciding to make it shared. Their requirements determine what can be reused and which work still belongs to each project.

Distinguish a reusable capability from unfinished work

A component becomes reusable when another team can understand its purpose, access it appropriately, and depend on its behavior. Source code in a repository is only part of that requirement. Documentation, permissions, tests, support arrangements, and clear limits determine whether the next team can use it.

Consider a hypothetical manufacturer building an assistant for service agents. The project creates a maintained product catalog with identifiers, specifications, and update rules. A later quoting workflow may reuse that catalog. It still needs its own pricing logic and approvals, but it can begin with a product source whose quality and ownership are understood.

Reuse what is common, preserve what is specific

Shared capabilities are most useful where requirements genuinely overlap. Authentication, approved data access, logging, and integration patterns are often candidates. Decisions that reflect a particular business process may need to remain local.

For a group of acquired businesses, a common customer data structure could simplify reporting while each business retains its own selling process. Forcing every business into identical workflows can create expensive exceptions. Review the differences before deciding what to standardize.

A useful design question is: what evidence shows that another workflow needs this capability? An identified second use gives the team something concrete to design for. An imagined future audience can lead to unnecessary complexity.

Measure the economics across the work

Keep a separate reuse ledger for the shared capability: its initial build cost, ongoing maintenance, adaptation effort and the specific work avoided by later projects. Record direct workflow savings separately. That makes it possible to judge reuse without counting the same benefit twice.

For the hypothetical product catalog, the first workflow might reduce time spent searching for specifications. A later project might avoid rebuilding the same data connection. Those are different benefits and should be recorded separately. Do not count the same labor saving twice or assume that time released becomes a cash saving.

Comparison requires care. If the second project is smaller, its lower delivery cost does not prove reuse caused the difference. Record scope, complexity, and the specific work avoided so the claim remains inspectable.

Include the cost of keeping it useful

Shared capabilities require maintenance. Sources change, business rules evolve, and dependent teams introduce new demands. An integration serving several workflows can also spread a failure across them.

Assign an owner, fund maintenance, and define how changes are tested and released. Track support effort and adaptation cost alongside usage. If a shared component requires extensive customization every time, reconsider its boundary. Reuse should earn its place through evidence.

Make a reuse decision at the next delivery review

Use a short record for each candidate capability:

• Second use: the named team, workflow and intended adoption date.
• Work avoided: the specific connection, cleaning, testing or interaction work that team would otherwise repeat.
• Additional cost: packaging, permissions, documentation, adaptation, migration and ongoing support.
• Ownership: the person responsible for changes, consumer compatibility and failure response.
• Evidence after adoption: actual adaptation effort, support burden and the work the second project avoided.

Share the capability when the second use is credible and the expected avoided work justifies the additional cost and dependency. Keep it local when consumers need incompatible behavior or no one can fund maintenance. Revisit the decision after adoption; a component that needs extensive rewriting for every consumer may have the wrong boundary.
