Planning for Unusual Cases in Everyday Business Work

A process may look straightforward until an order changes, a payment is corrected, or required information is missing. These situations are ordinary features of business life, even when each occurs infrequently. Software should handle them sensibly so that employees can resolve the case without losing reliable records or inventing an unofficial parallel process.

Start with the consequences of change

A hypothetical delivery business designs a booking workflow around a customer selecting a date and confirming an address. The unusual cases include cancellation, rescheduling, partial completion, and correction after a driver has been assigned. Each changes more than a status label: someone may need a new instruction, a record may need updating, and a customer may need an explanation.

Map those consequences with the employees involved. Identify what has already happened at the moment of the change and what can still be reversed. A cancellation before confirmation is different from cancellation after work has begun. Treating them identically may create confusion about responsibility and charges.

Record business rules in ordinary language. The owner decides the policy; the developer recommends how the system applies it consistently. Where rules are uncertain, mark the issue for a decision instead of asking the software team to infer the correct commercial response.

Include missing and contradictory information

Ask what should happen when essential details are absent, incomplete, or inconsistent. The booking may contain an address but no useful access instructions. Two messages may show different requested dates. Decide whether the employee can proceed, should request clarification, or must refer the case to an authorized person.

The Government Data Quality Framework identifies distinct dimensions of information quality. Its relevance is practical: a record can be populated yet unsuitable for the decision it supports. Software checks should reflect the business purpose, not merely whether a field contains something.

Avoid collecting extra information without a clear reason. More fields can add work for customers and employees while leaving the important ambiguity unresolved. Specify what is necessary for each stage and who is responsible for resolving an incomplete case.

Decide where human review belongs

Not every exception should become a complex automated rule. Some cases depend on judgment, a conversation, or circumstances that cannot be described reliably in advance. Provide a clear referral path and make the current responsibility visible.

For the hypothetical delivery business, a customer reporting a dangerous access condition may require a manager's assessment. The system can record the issue, prevent an inappropriate automatic confirmation, and direct it to the right person. It should not imply that a decision has been made merely because a form was submitted.

Explain who may override a normal restriction and what must be recorded. This protects the business's ability to understand the decision afterward. It also helps distinguish an approved exception from an employee's accidental workaround.

Review representative cases before reliance expands

Build a compact set of examples covering the normal path and the significant exceptions. Use realistic information and state the expected result. Ask employees to walk through the cases during review, including how they would explain the outcome to the customer.

The Government Digital Service's user-story guidance links completion to observable outcomes. Applying that principle to exception handling gives the business a practical way to verify corrections and cancellations rather than merely confirming that the relevant buttons exist.

Prioritize examples by potential consequence and likely frequency. The aim is not to predict every possible event. It is to make known difficult cases manageable and establish a dependable route for an unexpected one. Record issues discovered during introduction and use them to refine the workflow.

Preserve consistency as the product evolves

Holism's approach combines AI-assisted development with Software Product Line capabilities and a human developer. AI can accelerate implementation and exploration; the reusable foundation supports shared rules; the developer assesses how an exception affects information, permissions, and related tasks throughout the product.

This is valuable when a correction must be reflected consistently across customer views, staff work, and reports. The business owner supplies the meaning and priorities of the exception, while the developer handles the engineering decisions required to support it. That division allows customization without requiring managers to maintain technical logic themselves.

Planning for unusual cases means defining sensible outcomes, accountable review, and reliable records when the ideal path no longer applies. A system prepared for corrections and uncertainty is better aligned with everyday operations than one designed solely around flawless transactions.
