When spreadsheets stop working for your business

Look at what the workbook has become

Spreadsheets are useful for analysis, modelling and exploring a process that is still changing. Problems arise when a workbook quietly becomes the place where orders are authorised, stock is committed, cases are assigned or payments are released, without an equally clear operating process.

Modern spreadsheet tools can support shared editing and version history. Moving a file to shared storage may solve duplicate copies, but it does not by itself define who owns a record, what an approval means or which system should act on it. Assess the complete workflow rather than assuming that collaboration features settle those questions.

An illustrative example: stock commitments

Imagine sales and purchasing teams using one workbook to track customer demand and incoming stock. A salesperson changes a delivery date while purchasing adjusts a supplier quantity. Both edits are reasonable, but nobody is explicitly responsible for resolving the resulting shortfall. The sheet contains current numbers while the customer commitment remains unclear.

A useful improvement would give each order a stable identity, distinguish forecast demand from confirmed commitments, assign exception ownership and record the resolution. The analysis may stay in a spreadsheet; the commitment and its approval may belong in a workflow or existing business system.

Signs to investigate

Review recent errors and handoffs, then ask:

• Can people tell which records are authoritative, and which are working copies?
• Are formulas, reference data and manual overrides reviewed by an accountable owner?
• Can an important change be connected to the person, reason and approval behind it?
• Do people re-enter the same information into other systems?
• When work stops or an owner is absent, can someone else recover the process?
• Can access be limited appropriately without disrupting necessary collaboration?

Choose the smallest useful change

If the problem is inconsistent templates, unclear ownership or missing checks, start there. A controlled workbook may still fit. If the process needs structured records, role-based actions and dependable handoffs, examine whether an existing application can hold that responsibility. A focused new application may be appropriate where the workflow is distinctive.

Replacing every workbook can remove useful flexibility and create avoidable migration work. Keeping every process in spreadsheets can leave important controls dependent on personal discipline. Preserve spreadsheets for exploration and reporting where they work well, while moving operational responsibility to a system designed to carry it.

Make the first change measurable

Choose one workflow and document its current handoffs, duplicate entry and unresolved exceptions. Define what an improved process must demonstrate, such as a visible owner for every exception or an approval attached to each released order. Test that result with ordinary cases and corrections before expanding. Hyperwise can help separate the analysis people need from the workflow the business needs to control.
