Six fully dressed use cases for a made-up food bank scheduler, each with actor, stakeholders, guarantees, main scenario and a full set of extensions for the failure cases. Searches like "mbax 6640 week 6 assignment example", "mbax6640 week 6 sample" and "mbax 6640 week 6 example" land here.
What a finished MBAX 6640 Week 6 use case set looks like
A use case diagram opens the set, showing six use cases inside the system boundary and the actors connected to them: volunteer, group leader, coordinator, site lead, front desk and the court liaison. Each use case then fills a page or two in fully dressed form. For Book a Shift the fields read: primary actor, the volunteer; stakeholders and interests, including the site lead's concern with capacity and the guardian's with consent; preconditions; a minimal guarantee that nothing is recorded unless confirmed; a success guarantee; the trigger; a main success scenario of seven numbered steps; and extensions keyed to those steps, such as 3a, shift at capacity, waitlist offered, and 4a, volunteer under eighteen without consent on file, booking held pending consent. Every extension ends in a stated outcome.
How a MBAX 6640 Week 6 example is structured
The set moves from overview to detail to cross-checks. The diagram shows scope and actors together on one page. Use cases follow in the order a volunteer's week would meet them: register, book, cancel, check in, record hours, and the coordinator closing a shift for weather. Each uses the same fully dressed template so a reader always finds the same field in the same place. Main success scenarios are written as actor and system taking turns, one action per step, without interface detail. Extensions are numbered against the step where the condition arises, and each resolves to success, failure or a return to a named step. A closing table maps every use case to the requirements it satisfies and flags any requirement no use case exercises.
Actors at the boundary
The diagram places six use cases inside the system and connects each to its actors. The court liaison appears as an actor because the office receives hours reports, even though its staff never log in.
Stakeholders and interests
Cockburn's format records parties who are not acting but care about the result. The site lead's capacity limit and the guardian's consent rule enter the use case here, before the steps are written.
Guarantees, minimal and full
Book a Shift guarantees at minimum that no booking is recorded unless confirmed, and on success that the headcount, confirmation and reminder are all in place. Stating both tells a developer what must hold even when the scenario fails.
Turns, not screens
Steps alternate between actor and system and describe intent, not buttons. Interface detail waits for the interface specification, which keeps these use cases valid if the screens change.
Extensions resolved
Every numbered extension ends in success, failure or a return to a named step. An extension that trails off leaves a developer guessing exactly where the system is costliest to get wrong.
Traced to requirements
A final table links each use case to requirement identifiers from the requirements table. Rows with no use case are flagged for the consistency pass.
Where marks go in MBAX 6640 Week 6
Marks are won and lost in the extensions. A set whose use cases describe only the main success scenario has, in the course's terms, specified half a system, and it collects a limited share however polished the prose. Credit grows with each realistic failure condition keyed to the step where it arises and resolved to a stated outcome. The fully dressed fields are checked for presence and substance; stakeholders and interests, and the minimal guarantee, are the fields most often left thin. Steps that describe screens rather than intent draw comment. The diagram must match the text, with every actor and use case appearing in both. Tracing to requirement identifiers earns a separate portion and prepares the ground for the traceability matrix.

Forward your Week 6 use case prompt and rubric, plus the requirements table if you have it, and a fully dressed set with exception paths complete arrives within 24 to 48 hours; the opening request costs nothing. A case system other than the food bank can be named. Without one, the set specifies an imagined volunteer scheduler.
MBAX 6640 Week 6 questions, answered
What makes a use case fully dressed?
In Cockburn's format it includes the primary actor, scope, level, stakeholders and interests, preconditions, minimal and success guarantees, trigger, main success scenario and extensions, sometimes with technology variations. A casual use case gives only a paragraph. The fully dressed version forces decisions about failure and about who cares about the outcome, which is why this course asks for it.
How many extensions should each use case have?
As many as the realistic failure conditions at each step, which for a booking use case is often five to eight. Look at every step and ask what could go wrong there: missing data, a rule violated, an outside service not responding, the actor abandoning the task. Each should resolve to a stated outcome rather than trailing off.
Should use cases mention buttons and screens?
Generally not. Use case steps describe what the actor intends and what the system does in response, independent of interface. Writing enter the date and press submit ties the use case to one design and makes it obsolete when the screen changes. Your interface specification is the place for controls and layout, traced back to the use case steps.
