A full BU 421 Unit 4 demand planning record: a composite seasonal forecast converted into labor hours, then met by a level plan and a chase plan, both costed. Searches like "bu 421 unit 4 assignment example", "bu421 unit 4 sample" and "bu 421 unit 4 example" land here.
What a finished BU 421 Unit 4 demand planning record looks like
The finished record is a planning grid with argument around it. Period demand opens it as a table, with the seasonal indices computed beside the raw figures and the deseasonalized series shown in its own column so a reader can follow the adjustment. A conversion line states how many labor hours one unit consumes and where that rate comes from. The requirement in hours per period follows. Two full plans then appear as grids covering every period: a level plan holding output steady and absorbing the swing in inventory, and a chase plan matching output to demand and absorbing the swing in the workforce. Each grid carries its own cost lines for inventory holding, hiring, separation and overtime. A hybrid appears only after both pure plans are costed, and the recommendation names one.
How a BU 421 Unit 4 example is structured
Demand is taken as given rather than re-forecast, because this unit plans against a number the previous work produced and re-deriving it consumes the space the planning needs. Seasonal adjustment happens before conversion, since planning capacity against an unadjusted peak builds an operation sized for one period a year. The hours rate is stated once and applied identically to both plans, which is what makes their costs comparable at all. Both pure strategies are worked in full before any hybrid is attempted, so the hybrid can be argued from what each extreme actually cost rather than proposed as a compromise on principle. Cost categories are identical across the grids, including the ones that come out at zero. The recommendation closes with what the chosen plan assumes about the workforce it depends on.
The forecast taken as given
Demand figures come from the case rather than being re-derived, since this record plans against a number instead of producing one.
Seasonality removed before planning
Indices are computed and applied first, because sizing an operation against an unadjusted peak builds capacity that idles most of the period.
One conversion rate for both plans
The hours consumed by a unit are stated once and used identically everywhere, which is what makes the two plans cost comparable.
Level and chase both worked fully
Each pure strategy gets a complete grid before any blend is considered, so a hybrid can be argued from figures rather than instinct.
Identical cost lines across grids
Holding, hiring, separation and overtime appear in both plans even where a line comes out at zero, keeping the totals genuinely comparable.
What the chosen plan assumes
The closing states what the recommendation takes for granted about hiring speed, skill and the workforce absorbing the swing it requires.
Where marks go in BU 421 Unit 4
Records lose points by planning against raw seasonal demand. A workforce sized to the peak quarter and held there all year is the pattern the deseasonalizing step exists to prevent, and no amount of tidy arithmetic afterwards recovers it. Unit demand compared directly against staff numbers, with no conversion into hours, produces a plan whose figures cannot be added. Hiring and separation treated as costless make the chase plan win by omission. Inventory carrying cost left out does the same favor for the level plan. Backorders ignored where demand exceeds output hide a real consequence. Plans compared on different cost bases prove nothing. Staffing records, wage rates and production hours belonging to an employer cannot appear, and a labor rate invented and presented as market fact is its own problem.

BU 421 Unit 4 questions, answered
Which plan is normally the right answer?
Neither, until the costs are on the page. A level plan wins where holding inventory is cheap and the workforce is hard to replace; a chase plan wins where inventory is expensive or perishable and labor is flexible. The record earns its marks by showing which condition holds in the composite case, not by preferring one strategy in advance.
Where do the seasonal indices come from?
From the history the assignment supplies, averaged period by period against the overall mean, unless your instructions provide indices directly. Show the computation rather than the result alone. Where the history is too short to support an index, say so and plan on the raw series with that limitation stated, which reads better than an index built on two observations.
Should overtime count as a separate option?
Include it where the case gives a rate, because it is often the cheapest way to absorb a short peak without hiring. Treat it as a cost line in both grids rather than as a third plan, unless the instructions ask otherwise. Note any limit on hours per person, since an unlimited overtime assumption makes the arithmetic easy and the plan unusable.
