Included work
The statement of work should name the workflows, systems, environments, modules, interfaces, data sets, deliverables, and decision outputs included. For implementation work, identify whether configuration, custom development, migration execution, integration build, documentation, training, and launch support are included rather than leaving them implied.
If a task is material to success, name it. “Implementation” should not be used as a catch-all for work that has not been estimated or assigned.
Customer and third-party dependencies
Record the access, subject-matter expertise, approvals, source exports, identity-provider work, vendor coordination, infrastructure changes, legal interpretations, test users, procurement actions, and third-party changes that Zeph Tech does not control. Give each dependency an owner and a consequence if it arrives late or incomplete.
A dependency belongs in the schedule only when its owner and readiness condition are visible.
Unknown until discovery
Some estimates should remain conditional until source data, integration behavior, workflow exceptions, security requirements, accessibility scenarios, scale, hosting constraints, or records obligations are inspected. A bounded discovery output should identify what became known, what remains uncertain, and what decision can now be made.
Treating an unknown as a fixed assumption can create false certainty in both price and delivery dates.
Not automatically included
Do not infer legal advice, regulatory certification, independent audit or attestation, penetration testing, 24x7 support, unlimited migration cleanup, control of another vendor, guaranteed third-party uptime, or an unbounded customization commitment from a related service description. If any of those outcomes are needed, they require explicit scope and appropriate authority.
The useful boundary is simple: describe what will be done, by whom, on what evidence, and what proves completion.
Start the engagement with a scope register.
The 24-row worksheet captures operating outcome, authority, workflows, records, privacy, security, identity, integrations, infrastructure, migration, accessibility, performance, recovery, delivery responsibilities, testing, documentation, support, commercial constraints, third parties, exceptions, exit, success measures, and the first operating review.
