Set the purpose and scope
A stress exercise can support internal planning, a lender discussion or a formal regulatory requirement. Those purposes have different definitions and standards. Establish which exercise is being performed, the business entities covered and the decision it will inform. Formal regulatory interpretation and submissions require the appropriate qualified specialists. Business analysis should use the definitions and constraints they establish rather than treating an internal scenario as regulatory approval.
Specify the planning horizon and level of detail. A group-level earnings forecast can conceal a cash or capacity constraint within a particular entity or location. Identify the resources that can actually be transferred between businesses and any restrictions on doing so. An apparent surplus in one part of the group may be unavailable to meet an obligation elsewhere when the adverse conditions occur.
Describe the economic and operating assumptions
Define the events being considered and the assumptions that follow from them. These may include weaker demand, delayed customer payments, higher input prices or a disruption to a critical supplier. Explain the relationship between assumptions. A loss of supplier capacity can affect deliveries and customer receipts at the same time. Applying independent percentage changes to several forecast lines may miss that operational connection.
Document the evidence used to choose the assumptions and where judgment is required. Historical experience can provide a reference, but the current business may have a different product mix, funding structure or concentration of customers. Identify those differences. Where information is limited, test a range of plausible conditions and retain the ability to see which assumption creates a particular constraint.
Trace the scenario through the business
Translate the assumptions into the models used for normal management. Check the effect on orders, staffing requirements, production, inventory and cash. Preserve timing: a customer cancellation may reduce revenue before the business can reduce the resources committed to serving that demand. Supplier prepayments or replacement purchases can add a cash requirement even when the annual earnings effect appears manageable.
Review dependencies with the operational owners. A proposed reduction in output may be limited by maintenance schedules, contractual commitments or minimum staffing. A planned transfer to another facility may require certification or customer consent. Include the costs and time needed to make those changes. Finance should be able to reconcile the scenario result with the underlying assumptions and explain the reason for material movements. Check that model formulas still behave as intended under the adverse assumptions, including unusual volumes and delayed receipts. A formula designed for a normal trading range can produce misleading results outside it.
Assess the actions management could take
For each proposed response, state the person with authority to initiate it, the lead time, its financial effect and any conditions on implementation. Distinguish actions already available from actions requiring consent, financing or new systems. Check interactions between responses. Reducing inventory and changing suppliers may each look attractive alone but create an unacceptable service risk when implemented together.
Record the indicators that would prompt management to revisit the plan. A scenario does not predict exactly which event will occur; it helps identify exposure and prepare feasible responses. Keep the assumptions, model version and action assessment together. When the business changes its financing, customer mix or operating arrangements, review whether the previous exercise still represents the exposures management needs to understand.
