Network requirements checklist and document template

A network requirements checklist helps you record the users, services, constraints, acceptance criteria and open questions that a design must address. Use the copyable template below to turn a customer brief into a network requirements document another engineer can review.

If you're a network consultant or small MSP project engineer, a brief like this may sound familiar: “We need better Wi-Fi and reliable video calls.” The checklist gives that conversation a practical next step without assuming a device count, topology or performance target.

A useful first draft covers:

• Project scope, users, devices, locations and required services

• Source references for each requirement

• Physical, power, addressing and access constraints known so far

• Acceptance criteria to agree and assumptions to investigate

• Review owners, verification responsibilities and the next decision

Go to the copyable network requirements template, or follow the fictional office example first. You can use it in your existing document or spreadsheet.

Start with the facts in the brief

Riverbend Studio is a fictional 24-person office preparing a network refresh. Its initial brief asks for staff connectivity, guest Wi-Fi and reliable video meetings. A separate site note leaves the existing uplink capability unconfirmed.

Those are all the supplied facts for this exercise. We haven't been given device counts, a floor plan, application names, an approved guest policy or performance targets. The fictional teaching examples below were prepared for this guide, with draft requirements and no network tests performed.

Give the two sources short references: RB-S01 for the customer brief and RB-S02 for the site note. These are teaching labels, so you can follow the connections through the example. On a real job, use the actual document, message or meeting record and its date or revision.

Give each requirement four useful fields

Start with these fields beside a stable requirement ID:

• Requirement: What outcome is needed?

• Source: Where did the need come from?

• Acceptance question: What must be agreed before someone can judge the outcome?

• Reviewer: Who can resolve that question or approve the requirement?

Add a status so readers know whether they're looking at a draft or an agreed statement. Where a person's name isn't known, record the role and make assigning the person an explicit next action.

Keep the intended outcome separate from the proposed implementation. The customer may request guest internet access; the engineer will later propose how to provide it. That distinction lets the customer review the need before reviewing technical choices.

This approach is consistent with NASA's general systems-engineering guidance on clear, traceable, verifiable requirements. Its requirements checklist provides background principles you can adapt to the scale of your project.

Work one requirement through the review

Let's take Riverbend's guest Wi-Fi request. First, ask what is missing from this sentence:

“Visitors should be able to get online.”

We know the intended users and the broad need. We still need to agree the services they can reach, the areas where access is needed and the internal resources that should remain restricted. Any exception also needs an explicit decision.

Here is a useful first record.

Fictional teaching example · Draft D0.1 · Acceptance criteria pending

The source field preserves what the customer actually requested. The proposed-policy field shows where engineering interpretation begins. The acceptance question identifies a decision that a reviewer can help make.

Once the policy is agreed, replace the open wording with specific requirements. If permitted access and restricted access need separate review or tests, split them into clearly referenced statements. Keep the original source connection.

This record is ready for a useful conversation. Its pending fields also make clear why it isn't yet a finished acceptance specification.

Make quantities and performance questions explicit

Record staff connectivity as RB-R01 and video meetings as RB-R03. Then ask the questions that shape those requirements.

For staff connectivity, confirm the device types and quantities, where people work, required services and any growth allowance. Riverbend has 24 people; the brief doesn't establish that it has exactly 24 devices or 24 simultaneous meetings.

For video meetings, identify the applications, locations, representative busy-period use and acceptable user experience. Agree measurable criteria and how they will be assessed with the relevant customer and engineer. Leave unresolved thresholds visible with a decision owner.

A useful acceptance-criteria worksheet is:

Under [agreed conditions], [identified users or devices] can perform [specific task], meeting [agreed criterion], assessed using [agreed method].

The brackets are decisions to complete. A performance number becomes useful when its basis and method of assessment are understood.

Give the uplink question an owner

Riverbend's site note says the existing uplink capability is unconfirmed. Preserve that uncertainty in a short assumptions record.

• ID: RB-A01

• Working assumption: The existing uplink may be suitable for the proposed design.

• Source and confidence: RB-S02; unverified.

• Dependency: Any design decision that relies on that capability.

• Owner: Engineer arranging the site investigation; name to be assigned.

• Next action: Confirm the relevant capability and supporting information before approving dependent design decisions.

If the investigation changes the assumption, update the affected proposal and record why. Until then, the next engineer can see exactly where further information is needed.

Riverbend's worked answer

Here's a compact filled version. Keep the detailed RB-R02 record above beside it.

Three annotations explain the choices. “24 people” stays a staff count: device quantities need their own answer. Open design fields stay open: the brief supplies no addressing scheme. Review and execution have separate owners: agreeing this draft gives the later verification work a starting point.

Take the draft into the next decision

Use the reviewed requirements to prepare the proposed design, keeping unresolved dependencies visible. Then create the verification plan: which requirement each check addresses, its prerequisites, expected result and evidence to collect. Actual observations belong in a later execution record.

An engineer can review a proposed topology or configuration before implementation. Establishing how the network behaves requires the appropriate checks in the relevant environment. Keep those stages and their status visible in the handoff.

For your next brief, start with just one requirement record and one open assumption. Ask whether a colleague can identify the source, the pending decision and the next responsible person without another explanation. That's a practical improvement you can make today.

Explore NetSpec Studio if you'd like to see its approach to network planning and reviewable requirements. You can use every part of this checklist independently. Bring the same care to any generated draft: review the inputs, resolve open decisions and plan the separate verification work.
