Where orders wait longest is the finding DDBA 4990's Week 6 operations note is built on, supported by a process map, measured times and the one station limiting output. Searches like "ddba 4990 week 6 assignment example", "ddba4990 week 6 sample" and "ddba 4990 week 6 example" land here.
What a finished DDBA 4990 Week 6 operations note looks like
Built around a process map drawn as a row of boxes, one per step: quote, drawing, cutting, assembly, finishing, installation. Beneath each box sit two figures, time spent working and time spent waiting, taken from a week of job tickets. The narrative walks one typical order through the map and stops at finishing, where jobs queue for the single spray booth. A paragraph applies Little's Law, which ties the work sitting in a process to its throughput and the time each unit spends inside, to show that the queue in front of the booth explains most of the lead time. A short recommendation section targets that station only, and a glossary box fixes the meanings of capacity, throughput and lead time. The whole note runs two to three pages.
How a DDBA 4990 Week 6 example is structured
The note follows the product rather than the org chart, so each paragraph matches a box on the map. Times come from records, and the note says where: job tickets for one week, with the number of orders observed. Waiting and working are kept in separate figures throughout, because a station can look slow when it is actually starved. The bottleneck claim is then argued twice, once from the queue that forms in front of finishing and once from Little's Law, which turns the queue into an expected delay a reader can recompute. Goldratt's theory of constraints enters to justify the recommendation's narrow focus: improving any station except the constraint leaves output unchanged. Vocabulary is fixed in the glossary box before the analysis uses it, so throughput never slides into meaning capacity.
The map follows the product
Quote, drawing, cutting, assembly, finishing, installation, one box each, left to right. Departments do not appear, because the delay belongs to the order's path through the shop and not to whoever manages a step.
Working time and waiting time
Each box carries two figures from a week of job tickets. Cutting works four hours and waits one day; finishing works three hours and waits six days. The gap between those pairs is the note's evidence.
Little's Law, applied
Twelve jobs sit before the booth and it completes two a day, so a new job waits about six days. The note shows the arithmetic so a reader can repeat it with different figures.
One station, one recommendation
A second booth shift or a faster-curing finish, compared on cost. Following Goldratt, nothing is proposed for cutting or assembly, since gains there would only lengthen the queue at finishing.
A glossary box
Capacity is what a station could do, utilization what it does, throughput what leaves the shop, and lead time what the customer waits. Fixed early, these definitions keep later paragraphs from trading one word for another.
Where marks go in DDBA 4990 Week 6
Identifying the right constraint carries most of the credit, and graders check it against the note's own numbers: a recommendation aimed at cutting while the queue sits at finishing contradicts the evidence on the page. Separating waiting time from working time earns a band that many notes miss, since combined figures hide where delay actually accumulates. Little's Law is marked on application, so the relationship stated in a definition box and never used adds almost nothing. Terms are checked against the glossary, and a note calling utilization capacity in one paragraph loses precision credit. The recommendation is read for focus. Proposals improving every station at once suggest the author found the bottleneck and then declined to act on it, which undoes the analysis that preceded them.

DDBA 4990 Week 6 questions, answered
Does the operations note need real process data?
Real data is best and a scenario's figures are fine; invented precision is the problem. If you observe a process yourself, say how many orders you timed and over what period. If you estimate, label it. A note with rough, sourced times is more convincing than one with exact figures from nowhere, because the bottleneck argument depends on a reader trusting the numbers.
Is Little's Law too technical for a business essentials course?
Not in the form the note uses it. The relationship is simple arithmetic: work waiting divided by the rate it is completed gives the expected wait. Stating it once, citing it, and applying it to one queue is enough. The point is that a delay claim becomes checkable, which is the standard this course is building toward from its first week.
What if the process is a service rather than a product?
The same method works. A loan application, an insurance claim or a patient intake moves through steps, waits between them and hits a constraint. Map the unit that flows, whether a file or a person, and measure its waiting and working time at each step. Service notes often find the delay sits in an approval step rather than in the work itself.
