BriefSpec vs Microsoft Project:
the schedule isn't the implementation
Project schedules the work. It doesn't hold what the work produces. Most implementation teams need both dimensions and only have one.
Scheduling complexity. Resource levelling across shared pools, cost loading, earned value against a WBS, critical path on two thousand interdependent activities.
Artifact governance. Knowing what's been produced, verified and accepted — not just which dates elapsed — with the chain from clause to sign-off intact.
Run both. Project for programme scheduling across the portfolio. BriefSpec for the delivery itself. They solve different problems and don't collide.
What is the difference between BriefSpec and Microsoft Project?
Microsoft Project schedules the work — tasks, dates, dependencies, resource levelling, critical path and earned value. It does not hold what the work produces. BriefSpec holds the artifacts — requirements extracted from a signed SOW, test cases, execution records, defects, decisions and RAID — with the plan and the artifact state in the same system, so phase readiness reflects actual verification rather than elapsed dates.
Forty years of scheduling depth
None of which is the problem.
Project's engine is genuinely deep
Resource levelling across shared pools, cost loading, critical path with lead and lag, baselines, and earned value through BCWS, BCWP and ACWP. A skilled scheduler with Project can model a dependency network and forecast where it will bind better than almost anything else you can buy.
It has also moved. Since September 2024 the plans are Planner Plan 1, Planner and Project Plan 3, and Planner and Project Plan 5 — $10, $30 and $55 per user per month billed annually. Plan 3 carries the Project desktop client, Roadmaps, Baselines, Resource Requests and Copilot in Planner, which drafts task names and durations, spots who's carrying more than their share, and walks you through the impact of a slip on the end date.
Plenty of enterprises also own Project Professional outright on a perpetual licence and pay nothing monthly at all. Worth saying, because it means the licence was never where the money is.

Project knows "Requirements gathering" ran 5–25 January. It doesn't know the requirements.
Not their status, not their source clause, not which test cases cover them, not whether anyone verified them. When the dates elapse, the bar turns green — and the bar is describing the calendar, not the work.
An implementation isn't hard because sequencing 300 tasks is hard. It's hard because of what sits underneath them: 300 requirements pulled from a signed SOW, 400 test cases, 60 defects across three rounds, 30 decisions made in gate reviews, and a chain proving each obligation was delivered, tested and accepted.
Where the schedule stops being enough
Four places a scheduling tool meets implementation delivery and something has to give.
Green means the dates passed
The most dangerous signal in implementation delivery, and dangerous precisely because it isn't a lie. "Requirements phase: 100% complete" is accurate. It means the time allocated to requirements gathering has elapsed. It says nothing about whether 40 of them are still in Draft because the BA rolled off in week three and nobody picked up the reassignment.
So every gate review runs the same play. The PM shows green. Somebody from testing says we're actually about 60% through authoring, the requirements weren't stable until week three. Bars go amber. And the conversation that mattered happens three weeks after the data existed, because it only reached the schedule when a human carried it there.
In fairness: this is a boundary, not a flaw. Project tracks a task network faithfully. You can add custom fields and a Deliverables list, and Project Online and Server carried built-in Issues and Risks registers — but a custom field holding a weekly typed percentage is a report about the artifacts, not the artifacts.
The plan and the artifacts are the same system. A requirement still in Draft two weeks past its scheduled completion shows on the phase readiness dashboard because that's its actual state, not because somebody remembered to update a field. Gantt and artifact views are two lenses on one dataset rather than two tools compared on Fridays.
One schedule, seven tools for everything else
Project holds tasks, dates, dependencies and resources, owned by the PM, connected to nothing below it. Then: Excel for 300+ requirements, Excel for test scripts, Excel for pass/fail per tester, Excel for defects, Excel for RAID, SharePoint for FDDs and decision records, and Teams or email for the decisions that actually got made on a call.
Seven tools, five owners, no enforced connection anywhere. "Are we ready for the CRP2 gate?" isn't a question anyone can answer by looking. It's four to six hours of assembly, four times across a twelve-month programme — the better part of a working week per project spent building a picture rather than acting on one.
And every one of those handoffs is a place the answer can be wrong without anyone noticing.
Requirements, test cases, executions, defects, RAID items, decisions and documentation live in one system with enforced relationships. Readiness is a dashboard reading live state, not a deck. The gate review starts from the data instead of arriving at it.
Resource levelling and artifact governance are different superpowers
Project's real strength is levelling. Give it the pool — Sarah at 40 hours, James at 32 after Thursdays — plus assignments and the dependency network, and it shows you precisely where you've overcommitted someone. On construction, manufacturing and engineering programmes, where the binding constraint genuinely is skilled labour against a fixed task network, that capability is the job.
Implementation work binds somewhere else. The constraint is rarely hours. It's we're not certain what we're configuring, we've verified less of it than the schedule implies, and we can't yet show that what we tested matches what we sold.
Project can't do that, and was never built to. It's the wrong criticism to make of a scheduler and the right reason not to run an implementation on one.
Knowing, at any moment, what's been extracted, verified, tested, broken, decided and signed — and whether the line from contract to sign-off holds. Phases are first-class with enforced predecessors and separate build and review scoring, so the go/no-go is a data question rather than a judgement call.
Testing is invisible from the Gantt
Project tracks that "UAT Execution" runs 10–24 March. It doesn't track who ran which script, what they found, whether a failure produced a defect, whether the defect links to a requirement, or whether the fix was reverified. All of the actual evidence lives in spreadsheets or Jira, where the schedule can't see it.
Gate review. Show me every Critical defect from UAT is resolved and verified. The PM opens the defect log, filters severity, filters phase, filters status, then cross-references each resolved item against the results sheet to check it was actually retested. Forty-five minutes for a real answer. Five minutes for "most of them, I think," which is worth nothing in front of an auditor.
The lifecycle is visible from any artifact it touches. Open a requirement, see every defect filed against it. Open a defect, see the execution that found it, the tester, the resolution, and whether verification passed. "Which Critical UAT defects are still open?" is a filter.

The licence isn't the expense. The artifact layer is.
A 10-person team over twelve months. The spreadsheet layer below is the same stack we cost on our Excel comparison — because it's the same stack. Labour is modeled from our own engagements, not measured.
Project + spreadsheet layer
~$51,350BriefSpec
~$9,000Roughly 80% lower, and almost none of it is licence cost. It's the artifact layer, which stops being a thing you maintain by hand. Keeping Project for programme-level scheduling? Add its $3,600 back — the arithmetic still works, because the $42,650 is what actually goes away.

BriefSpec vs Microsoft Project, answered
What is the difference between BriefSpec and Microsoft Project?
Microsoft Project schedules the work: tasks, dates, dependencies, resource levelling, critical path and earned value. It does not hold what the work produces. BriefSpec holds the artifacts — requirements extracted from a signed SOW, test cases, execution records, defects, decisions and RAID — with the plan and the artifact state in the same system, so phase readiness reflects actual verification rather than elapsed dates.
Can Microsoft Project track requirements and test cases?
Not as artifacts. Project supports custom fields and a Deliverables list, and Project Online and Project Server shipped built-in Issues and Risks registers, so the picture is not completely bare. But a custom field holding a percentage that somebody types in weekly is a report about the artifacts, not the artifacts themselves — Project cannot tell you which requirements are unverified or which test cases failed.
Why is a green Gantt bar misleading on an implementation?
Because it is accurate about the wrong thing. Requirements phase 100% complete means the time allocated to requirements gathering has elapsed. It says nothing about whether 40 requirements are still in Draft because the business analyst rolled off in week three. Project tracks a task network faithfully but has no visibility into artifact state, so it cannot warn about a gap it cannot see.
What are Microsoft Project plans called now and what do they cost?
Project Plan 3 and Project Plan 5 were renamed Planner and Project Plan 3 and Planner and Project Plan 5 in September 2024, and Project Plan 1 became Planner Plan 1. List pricing is $10, $30 and $55 per user per month billed annually. Plan 3 includes the Project desktop client, Roadmaps, Baselines, Resource Requests and Copilot in Planner. Many enterprises also own Project Professional outright on a perpetual licence.
Can BriefSpec replace Microsoft Project entirely?
For implementation delivery, usually yes — BriefSpec includes a Gantt with phase-aware bulk date shifts and dependency enforcement. For programme-level scheduling across a portfolio, resource levelling across shared pools, or formal earned value against a WBS where the contract requires it, Project remains stronger and many PMOs keep both.
How much does running an implementation on Microsoft Project actually cost?
The licence is not the expense. Modeled for a 10-person team over twelve months, Planner and Project Plan 3 is about $3,600 a year, but the spreadsheet artifact layer that has to be maintained alongside it runs roughly $42,650 in labour, plus around $5,100 in schedule maintenance. The same team on BriefSpec models at about $9,000 all-in.
