The BU 421 Unit 8 supply chain scheduling file complete: a composite chain mapped with lead times, jobs sequenced at the constraint, and one disruption traced through. Searches like "bu 421 unit 8 assignment example", "bu421 unit 8 sample" and "bu 421 unit 8 example" land here.
What a finished BU 421 Unit 8 supply chain scheduling file looks like
The finished file has three parts that reference each other rather than three separate papers. The chain map comes first, tiers named with the lead time and the variability of each link, and the cumulative time from raw material to customer computed along the path. A sourcing section follows with a supplier scorecard: criteria weighted before any supplier is scored, scores entered, and the winner named with what the weighting decided. The scheduling section then takes a job table with processing times and due dates, applies a named sequencing rule, and reports flow time and lateness for the resulting order. The same jobs run under a second rule so the measures can be compared. A disruption is traced through the map, and a mitigation closes with what holding it would cost.
How a BU 421 Unit 8 example is structured
The chain is drawn before the schedule because a sequencing decision at one work center means little until the reader knows how much lead time sits upstream of it. Lead times accumulate along the path rather than being listed separately, since the cumulative figure is what the customer promise actually rests on. Scorecard weights are fixed before any supplier is scored, which is the step that stops the weighting being adjusted to confirm a preference. One sequencing rule is applied consistently and a second is run on the identical job set, so the comparison isolates the rule instead of the data. The disruption is traced through the map already on the page rather than described in general terms. The mitigation is costed last, because holding buffer stock or a second supplier is never free and the file should say what it spends.
Chain mapped before any scheduling
Tiers and their lead times are laid out first, since a sequencing choice at one center means little without the upstream time visible.
Lead times accumulated along the path
The file computes total time from raw material to delivery rather than listing links separately, because the customer promise rests on that sum.
Scorecard weights fixed before scoring
Criteria and their weights are settled in advance, which prevents the weighting from being adjusted afterwards to confirm a supplier already preferred.
One rule applied, a second compared
The identical job set is sequenced twice under different rules, so any difference in the measures comes from the rule and nothing else.
A disruption traced through the map
The delay is followed link by link along the chain already drawn, arriving at a specific date rather than a general warning.
Mitigation priced before it is recommended
Buffer stock, a second source or expedited freight each carry a cost line, since protection against disruption is never available for nothing.
Where marks go in BU 421 Unit 8
Files lose marks where the three parts never meet. A chain map, a supplier choice and a schedule presented in sequence with no connection between them satisfy three small prompts and miss the assembly the closing unit is testing. Chains drawn without lead times cannot support a disruption trace at all. Suppliers chosen on price with a scorecard added afterward to justify it invert the method. A single sequencing rule applied and never compared gives a marker no basis for judging it. Flow time reported as lateness, or the two averaged together, confuses measures with different meanings. Disruptions discussed in general terms without touching the schedule prove nothing. Supplier contracts, negotiated rates and delivery performance records from an employer stay outside the file entirely.

BU 421 Unit 8 questions, answered
Which sequencing rule should the file use?
Use the rule your assignment specifies. Where no rule is fixed, pick one that suits the measure the case cares about. Shortest processing time tends to minimize average flow time, while earliest due date tends to reduce maximum lateness. Run a second rule on the same jobs and report both sets of measures, since the comparison is where the reasoning becomes visible.
How many tiers does the map need?
Enough to reach the point where the disruption you trace begins, which is usually two upstream and one downstream of the composite firm. More tiers add drawing without adding argument. What every link does need is a lead time and some sense of how much that time varies, because a stable long link and a volatile short one behave very differently.
Can I reuse the process and capacity work from earlier units?
Most instructions expect it in a closing unit, and building on your own earlier work is the point. Correct whatever was marked down the first time, and rewrite each piece to serve the question this file answers rather than its original prompt. Pasted sections still answering an earlier unit are the weakness graders report most often on final submissions.
