Unit 9 Assumption and Constraint Log
[Instructor Name]
[Date]
Ashby Mills, Linden Park and every entry, owner and date are composite and illustrative; the sources cited are real.
How the Log Works
An assumption is something the plan treats as true without proof; a constraint is a limit the project must work within, set by a document, a law or a physical fact. The two are kept in one log because both shape the plan, but they are handled differently. Each assumption has an owner who must confirm it by a date, and a statement of what happens if it proves false. Each constraint cites the document or source that imposes it, so that anyone who questions it can check. Larson and Gray (2021) note that unexamined assumptions are among the most common sources of project risk, and the log exists to examine them one by one.
Assumptions differ from risks. A risk is an uncertain event that may or may not happen; an assumption is a belief the plan already depends on. If an assumption proves false, it becomes an issue at once.
Assumptions, Sorted by Consequence
The assumptions run from most to least costly if wrong, not in the order they were written. A-06 comes first because a soft base would double the cost; A-03 comes near the end because weak demand in the first season would delay a league but would not stop the courts from opening. Sorting this way tells the coordinator which confirmations to chase first when time is short.
A-06: The asphalt base under courts 3 and 4 is sound. Owner: surfacing contractor. Confirm by: core results, done; northeast corner rechecked when the old surface is removed. If false: base reconstruction roughly doubles cost; the project is re-scoped. Status: confirmed in four of five cores, open for the corner.
A-02: The state grant of $40,000 is awarded by June 30. Owner: recreation coordinator. If false: the project drops to six courts within $150,000. Status: open.
A-04: The contractor's price of $171,400 holds through August. Owner: finance director. If false: contingency absorbs up to $17,140. Status: confirmed in the bid terms.
A-11: The high school's spring practice fits on courts 1 and 2 plus the middle school's two courts if construction slips into spring. Owner: parks director with the athletic director. If false: construction cannot extend into March. Status: confirmed by letter.
A-08: Acoustic panels reduce sound at the nearest lot line to about 51 decibels. Owner: noise consultant. If false: hours of play must be limited. Status: open until installation testing.
A-09: The pickleball club donates windscreens for all eight courts. Owner: club board. If false: about $3,200 from contingency. Status: pledged in writing.
A-12: Public works can absorb about 40 crew hours a year of upkeep. Owner: public works superintendent. If false: upkeep is contracted out. Status: confirmed.
A-14: At least 18 suitable working days occur between mid-August and late October. Owner: contractor. If false: completion moves to spring. Status: open, based on five-year records.
A-15: No utility lines cross the area of the new accessible path. Owner: public works. If false: path is rerouted at added cost. Status: confirmed by locate request.
A-03: Demand will fill eight courts in the first season. Owner: recreation coordinator. If false: league launch is delayed. Status: open.
A-17: No site plan review will be needed. Owner: planning board. Status: failed; the board voted in month two to require a review. Effect: five weeks added before construction, absorbed within the weather margin only if work starts by early September.
Constraints, With Sources
C-01: Total council appropriation is $150,000. Source: capital budget resolution.
C-02: Daytime sound at a residential lot line may not exceed 55 decibels. Source: town noise bylaw.
C-03: Acrylic surfacing only above 50 degrees and rising, with 24 dry hours. Source: manufacturer's application specification.
C-04: The school district has spring access to all four courts. Source: shared-use agreement, section 3.
C-05: Court dimensions and net heights follow the sport's official rules. Source: the USA Pickleball (2024) rulebook.
C-06: The accessible route must not exceed a 5 percent running slope. Source: town accessibility standard.
C-07: Changes over $5,000 need the director's approval. Source: project charter.
C-08: Signage on the lakefront side is limited in size. Source: park sign policy.
C-09: Construction may not block the parking lot on high school match days. Source: shared-use agreement, section 5.
C-10: Grant funds must be spent within 18 months of award. Source: state grant program terms.
C-11: The contractor must carry the town's required insurance. Source: bid documents.
A constraint without a source is only someone's memory, and memories do not survive a council meeting.
Reviewing the Log
The recreation coordinator reviews the log at each milestone and at any change request. When an assumption is confirmed, its status changes but the entry stays, so the reasoning remains visible. When one fails, it stays in the log with its consequence and becomes an issue in the project's issue list. PMI (2021) treats assumptions as part of the project's baseline knowledge, to be validated as work proceeds, and this log is how that validation is recorded.

MT245 Unit 9 instructions, in plain terms
The ninth unit asks students to record the assumptions a project depends on and the constraints it must work within. The prompt usually expects assumptions and constraints kept distinct: an assumption is a belief the plan treats as true, a constraint is a limit set by a document, law or physical fact. Each assumption needs an owner, a date or event by which it will be confirmed and a statement of what happens if it is false. Each constraint needs a source a reader could check. Sorting assumptions by consequence tells the manager what to confirm first. Failed assumptions should stay in the log with their effect. About three pages of table in APA 7 is typical, with a short explanation of how the log is reviewed.
How this MT245 Unit 9 example is built
The log first defines assumptions and constraints and separates assumptions from risks, citing Larson and Gray. Eleven assumptions follow, sorted from most to least costly if wrong, from the base and the grant to first-season demand, each with an owner, status and consequence. The failed site plan assumption stays in the list, with a margin note on keeping failures visible. Eleven constraints follow, each with its source: the budget resolution, the noise bylaw, the surfacing specification, the shared-use agreement, the rulebook and others. The highlighted line says a constraint without a source is only memory. A closing section sets a review routine at each milestone and change request with the PMBOK Guide, marked by a third note.
Reading the MT245 Unit 9 grading rubric
Logs earn credit for distinguishing assumptions from constraints, giving each assumption an owner and consequence, sourcing every constraint and keeping the log current. A consequence stated in concrete terms, such as the project re-scoped or two courts dropped, earns more than a general risk label. Graders reward sorting by consequence, which shows the writer understands priorities. Constraints with document sources show they can be checked. Keeping failed assumptions, with their effect, demonstrates the log is a working record. Consistency with the feasibility assessment and charter figures matters. A clear table, a brief review routine and accurate citations complete the marks.
Common MT245 Unit 9 mistakes, and how to avoid them
The most common confusion is listing risks in an assumption log, such as rain might delay work, rather than beliefs the plan already depends on, such as enough dry days will occur. Another is constraints with no source, which leaves them open to challenge. Some logs give assumptions no owner or date, so nobody confirms them. Others delete assumptions once confirmed or failed, which hides the reasoning. Check that each consequence matches the plan's fallback. Send your project's plan and documents, and a writer can draw out the assumptions, cite the constraints and sort the log by what would hurt most.

Assumptions come from the particulars of each project, so send the scenario, whatever charter, scope or feasibility work exists, and Unit 9's directions and rubric. A first log is free, back within 24-48h, every assumption given a person to verify it by a set date and every constraint tied to its source.

MT245 Unit 9 questions, answered
Is an assumption the same thing as a risk?
No. An assumption is a belief the plan relies on before anyone has checked it, such as a sound asphalt base. A risk is an uncertain future event that could affect objectives. An assumption left unconfirmed carries risk, and many teams move it to the risk register once its confirm-by date passes. The example keeps both documents and links them by ID.
Why cite a source for every constraint?
Because a limit without a source invites debate about whether it is real. Citing the council vote, the noise bylaw or the manufacturer's temperature floor settles that immediately. It also shows who could change the constraint, if anyone, which matters when a stakeholder asks for an exception the project cannot grant.
Should failed assumptions stay in the log?
Yes. A failed assumption records what the plan once believed and what changed when it proved wrong, which is useful to anyone reviewing the project later. The example keeps its failed site plan entry with a status of failed and the five weeks it added, rather than deleting the row and hiding the change.
Where can I find a free MT245 Unit 9 sample paper?
This page carries the complete MT245 Unit 9 assumption and constraint log. It lists eleven assumptions sorted by consequence with owners and fallbacks, and eleven constraints each tied to its source document.
Which assumption failed in the MT245 Unit 9 sample?
A-17, that no site plan review would be needed. The planning board required one, adding five weeks before construction, which the fall weather margin can absorb only if work starts by early September.
