Supplier diversity programs defended on the business case are the most exposed to political change

The business case for supplier diversity

For most of the last two decades, the argument for supplier diversity in the United States and Australia has rested on a familiar set of claims: that diverse suppliers make supply chains more resilient, that diverse teams perform better, and that inclusive procurement drives innovation. This business case was constructed to persuade people who preferred to avoid a direct moral argument, and for a long period it was effective, largely because nobody was testing it seriously.

That argument is now failing in the United States, the market where it originated, where supplier diversity programs have faced sustained legal and political challenge, and our assessment is that the programs most exposed to being wound back are those defended mainly in the language of the business case. The weakness is structural, because a business case is a claim about outcomes that can always be disputed, and once someone with authority disputes it the program has no other foundation. A target expressed as a percentage of contract value and reported against each year records what an organisation actually did, which makes it harder to dispute and much harder to abandon quietly, since any abandonment appears in the next report.

The Indigenous Procurement Policy as an Australian example

In Australia the clearest example is the Indigenous Procurement Policy, whose targets of 3.25 per cent of eligible procurement this year, rising to 4 per cent by 2029 to 2030, are not defended on the basis that Indigenous suppliers are more innovative. The policy is defended as a commitment with a number attached, with published performance against that number and defined rules about when a supplier must be approached. It has been criticised, debated and adjusted, but it would be difficult to drop quietly because the reporting structure would show the change in the year it occurred.

A spending figure of this kind describes activity in a stated period and no more. Interpreting it requires knowing which purchases were included, how eligibility was established and whether the reporting basis has changed, and the figure can be accurate without demonstrating every benefit claimed for the program. The limitation works in the program’s favour, because a program that reports its activity can be held to account against that record, while the promised outcomes of a program can only be debated.

Continuity when personnel change

When a new procurement manager inherits a commitment to diverse suppliers, the immediate task is to identify who is covered, what has been done and where the records are kept, and a persuasive business case provides none of that information, however prominent the public statement on the website may be. A usable handover would include the definition, the process, the responsible team and the evidence from previous years, and without it the next review begins with a further debate about what the commitment was meant to mean.

Targets can be altered and reporting can cease after changes in leadership, budgets or law, and clear records allow anyone reviewing the program to identify what changed, where otherwise continuity would be assumed from an unchanged sentence on a website. Clear records can also reveal problems with the measure itself, such as a target that concentrates work among established suppliers, a reporting system that double counts, or a verification requirement that costs small businesses more than the opportunity is worth. Problems of this kind call for closer scrutiny of a measured program and give no grounds for preferring programs that cannot be measured at all.

Implications for a new Australian supplier category

The same reasoning applies to anyone proposing a new supplier category in Australia, LGBTIQA+ or otherwise, because the case made to establish a program is seldom enough to sustain it once political conditions change. A program that relies on the business case to justify its existence is making a claim it will eventually be required to prove, under conditions set by those who want it to fail. A program built on a defined category, a verification method and a reportable number makes a narrower claim, which is easier to defend under scrutiny.

This analysis does not claim that the moral argument is wrong or that businesses gain nothing from diverse supply chains. The moral argument explains why a category should be built and the mechanism determines whether it survives, so neither can stand in for the other. Any proposal for Australia should be assessed on its mechanism before its moral case, because by the time the mechanism is under challenge the moral case has usually already been settled.
