A business analyst (BA) elicits requirements for the sales order processing of multiple product lines.
Elicitation reveals that the business processes for the sales orders of most products follow similar activity patterns that have been established over a number of years. Some of the new proposed seasonal products, however, will necessitate major variations in the process flow of some departments. The seasonal products are likely to be different every year. The business needs to carefully adapt its business practices so that the significant but seasonal variations in some of the business processes for the new products are handled adequately without disrupting the processes for the other established products.
Which of the following approaches must the BA take to manage the requirements for sales order processing in the long term?
