A validated script over 41 linked activities shifts the controlling path from the filler to the utility upgrade, finishing on working day 187, in GM592's Unit 7 network. Searches like "gm 592 unit 7 assignment example", "gm592 unit 7 sample" and "gm592 unit 7 example" land here.
What a finished GM592 Unit 7 schedule network diagram looks like
Five pages and an appendix. An activity table gives each of 41 activities an ID, WBS code, duration carried from the estimate worksheet, predecessors and link type. Most links are finish-to-start; one start-to-start with a three-day lag lets sleeve artwork begin while label filings are drafted, and one finish-to-finish ties operator training to the site acceptance runs. An activity-on-node diagram follows, heavier borders marking the controlling chain: utility application, utility design, transformer delivery, service installation and energizing, line power-up, site acceptance, first saleable run. The finish falls on working day 187. The equipment chain holds 14 days of float, the permit chain 9 and label approvals 22. A second table prints the script's early and late dates and total float. The appendix carries the script, its input file and the output of two test runs.
How a GM592 Unit 7 example is structured
Logic is fixed before any date appears. The script then checks its input before calculating: it refuses to run on a loop, a predecessor that does not exist, or an activity with nothing before or after it other than the start and finish milestones. Only then do the forward and backward passes run, with total float as the gap between late and early dates. The controlling path is read from the zero-float activities rather than from the diagram's appearance. Two test runs confirm the script behaves as the logic predicts: five days added to transformer delivery moves the finish by five, while five added to the filler moves nothing. A note states the calendar once, a five-day week without brewery holidays, and flags the permit chain as near-critical.
Links typed before dates
Most links wait for a predecessor to finish; the exceptions are a start-to-start with a three-day lag for sleeve artwork and a finish-to-finish for training, each marked where it applies.
Input checked, then computed
Loops, missing predecessors and dangling activities stop the script before it calculates anything, since passes run over broken logic produce confident dates that mean nothing.
The path nobody expected
Utility application through energizing, power-up and site acceptance carries zero float, while the filler everyone watched sits two weeks clear of the finish date.
Two runs that test the code
Five days added to a controlling activity moves the finish five; five added to the filler moves nothing, which is how the float column earns trust.
Nine days on the permit chain
The city electrical permit and inspection sequence is named as near-critical, because one slow review cycle would hand it the controlling role.
Where marks go in GM592 Unit 7
Declaring the controlling path instead of deriving it is the error network assignments are generally built to catch, and it shows whenever a narrative names the chain everyone expected while the float column shows another. Scripts and scheduling software earn nothing merely by being present: code whose output was never tested, or that silently starts an orphaned activity on day one, weakens every date it prints. Dependencies typed finish-to-start throughout, where work plainly overlaps, draw regular comments. Durations appearing with no link to the estimate worksheet break the chain the plan relies on. Hard date constraints used to force a finish override the logic they sit on. Near-critical chains left unmentioned suggest float was calculated and never read. Calendars never stated, weeks and working days mixed, and diagrams too crowded to follow are the lighter recurring notes.

Scheduling logic belongs to one project, so the activity list or estimate worksheet the section is using has to come along, plus the Unit 7 prompt and rubric and any software requirement. Within 24-48h a first network returns at no charge, both passes computed and tested, and the controlling path read from the float column instead of assumed.
GM592 Unit 7 questions, answered
Does the critical path have to be calculated by a script?
Seldom. Scheduling software, a spreadsheet or a worked calculation on paper is usually acceptable, since what earns credit is sound logic backed by visible passes. The example relies on a short script because 41 activities with mixed link types make arithmetic slips likely by hand. Whichever tool is used, printing the passes and testing the output matter more than the tool itself.
How can a schedule script be tested?
By changing an input whose effect the logic predicts and checking the output agrees. Lengthening a zero-float activity should move the finish by the same amount; lengthening an activity with float, by less than its float, should move nothing. The example runs both tests and prints the results in the appendix beside the script.
What does near-critical mean?
An activity chain whose total float is small enough that a plausible delay would make it controlling. There is no fixed threshold; many plans use a figure tied to their own estimate ranges. The example names the permit chain at nine days because its estimate range is wider than that, so one slow review could take over.
