For MT246 Unit 4, twenty-two activities are linked and passed forward and backward, and an eleven-activity chain from plan approval through soft launch sets the finish at working day 79. Searches like "mt 246 unit 4 assignment example", "mt246 unit 4 sample" and "mt246 unit 4 example" land here.
What a finished MT246 Unit 4 network and critical path looks like
Five pages built by hand, an approach most undergraduate sections allow. Twenty-two activities each receive a letter in the opening table, with a breakdown code, the working days set in the estimating exercise, and predecessors, all finish-to-start. A node diagram comes after that, each box carrying its four dates and its total float, with the controlling chain drawn heavier: plan approved, upfitter layout, plan review, upfit, generator and electrical, fire marshal, health inspection, wrap, crew training, first smoke and soft launch, ending on working day 79. A float table ranks everything else. The city license and fire suppression each carry one day, the draft menu three and the commissary letter five, while wrap design and menu testing carry more than fifty and hiring forty-nine. A half page compares three versions of the truck link.
How a MT246 Unit 4 example is structured
Logic is settled before any arithmetic. Each link carries a reason a reader can check, such as the health department approving plans before the upfitter may cut metal. The forward pass then gives early dates, the backward pass late ones, and total float is the gap between them. Whichever boxes show zero float form the controlling chain; appearance plays no part. The truck link is the page's distinctive move. The first draft let the wrap and the health inspection run side by side after the fire marshal, finishing on day 78 with the city license controlling, which was physically impossible. Two corrected versions were computed: inspection first finishes on day 79 and makes the wrap, training and first smoke critical, while wrap first finishes on day 83. A short narrative explains the choice and names the one-day chains.
A reason on every link
Plans approved before metal is cut, the fire marshal before the health inspector, the health permit before the city license: each dependency names the rule or office that imposes it.
Both passes, box by box
Early and late dates are written into every node of the diagram, so a grader can check any single activity without recomputing the whole network from the start.
One truck, two appointments
The first draft sent the truck to the wrap shop and the health inspector at once. Adding the missing link moved the finish from day 78 to day 79 and changed which chain controls.
Three versions, computed
Wrap and inspection in parallel, inspection first, wrap first: 78, 79 and 83 working days, with the impossible first version kept on the page and labeled as rejected.
One-day chains named
The city license and the fire suppression certificate each hold a single day of float, close enough to controlling that the schedule treats them as critical in practice.
Where marks go in MT246 Unit 4
Graders check a critical path against the float column, so a path chosen by eye, whichever chain looks longest on the diagram, gives itself away quickly and costs heavily. Missing dependencies cost almost as much, because a network that leaves out a real constraint yields a critical path in name only, and scenarios frequently plant exactly such a constraint. Passes with no arithmetic shown cannot be verified. Activities left dangling, with nothing after them but the finish, let the backward pass quietly overstate their float. A float table nobody interprets, with its one-day chains left unremarked, wastes the calculation. Durations that no longer match the estimating exercise break the thread between units. Diagrams too crowded to trace, and leads or lags that nobody explains, draw the lighter comments.

MT246 Unit 4 questions, answered
What if a resource, not a task, forces the order?
Then the network needs a link it would not otherwise have. The truck in the example is a physical resource: it cannot sit at the wrap shop and the inspection bay at once, so one appointment has to follow the other. Some courses leave this to resource leveling later; adding it now keeps the critical path honest. The sample shows both orders and why one was chosen.
Why keep the rejected version of the network in the paper?
Because it shows the reasoning a grader wants to see. The parallel version finished a day sooner and named a different controlling chain, and only the question of where the truck would physically be exposed it. Keeping it, labeled as rejected, shows the critical path was tested rather than accepted. If your instructions want the final network only, the comparison moves into a short note.
Why are all the links finish-to-start?
Because in this project each step genuinely waits for the one before it: the inspector will not come until the fire marshal signs, and the city will not license a truck without a health permit. Overlap links belong where work can really run together. The example considered a start-to-start link for training and rejected it, since the new cooks cannot train on a truck still at the wrap shop.
