CBAP Question #448: Real Exam Question with Answer & Explanation

The correct answer is A. Elicit requirements for a system to coordinate in advance order processing activities with all trips. The most cost-effective BA recommendation is to elicit requirements for a system that pre-coordinates order processing with truck trips, targeting the root inefficiency rather than adding headcount or equipment.

Question

A major manufacturer of popular beverages has appointed a local distributor to serve a specific territory. The demand for the beverages has a pronounced seasonal pattern. The distributor performs well overall, but is repeatedly unable to keep up with fulfilling many customer orders during peak demand periods. The distributor's current delivery capability is stretched to deliver 60 tons of merchandise per day whereas the season's peak demand periods need a daily delivery capability of up to 100 tons. The distributor is under pressure to fully meet the year-round market demand in order to stay in business. The distributor's management wants to identify and consider more cost-effective options as resorting to adding more trucks and drivers would not be economically feasible. A business analyst (BA) has spent several days observing and measuring the warehouse activities to understand the situation and to gain insights into possible solutions. The delivery workflow is a four- step process: (1) picking the orders and assembling them on trays, (2) bringing the trays to the loading bay, (3) loading the orders into trucks, and (4) delivering the orders to customers. As the following table illustrates, overall performance depends is dependent on five major resources: (1) the workers who pick the orders and load them into trucks, (2) the tallyers who check the orders, (3) the drivers, (4) the trucks, and (5) eight loading bays (LBs). Preparing a customer order for loading takes about one hour. Upon the BA's observation, only 30% of trips have their orders available for loading when a truck arrives. This causes a waste of both the truck's and the driver's time. What should the BA recommend to eliminate such waste?

Options

  • AElicit requirements for a system to coordinate in advance order processing activities with all trips
  • BBegin assembling orders for the next trip immediately following the truck's departure
  • CHire more warehouse staff (workers) so that order assembly is done faster and less waiting occurs
  • DAsk the drivers to call the operations team member if they are going to be late

Explanation

The most cost-effective BA recommendation is to elicit requirements for a system that pre-coordinates order processing with truck trips, targeting the root inefficiency rather than adding headcount or equipment.

Common mistakes.

  • B. Starting order assembly immediately after a truck departs reduces idle time marginally but does not scale total capacity to meet 100-ton peak demand.
  • C. Hiring additional warehouse staff increases recurring labor costs and mirrors the rejected option of adding drivers - it is not cost-effective.
  • D. Asking drivers to call when late is a reactive communication workaround that does not improve throughput or resolve the structural delivery gap.

Concept tested. BA process improvement recommendation over resource expansion
