Businesses engage suppliers for many different reasons. The question is, if you’re engaging experienced specialists, why are they so often underperforming?
The answer might lie in your leadership style. Inspired by the vast volume of research on the impact of leadership style on staff performance, Grosvenor surveyed 119 organisations in Australia to shine a light on the impact of supplier leadership on business outcomes.
The study results were quite astounding.
Read on to find out how changing the way you lead can result in suppliers that deliver even more than you paid for.
Transformational leaders receive 27% higher supplier performance
We decided to use the Multifactor Leadership Questionnaire (MLQ) framework developed by Bernard Bass and Bruce Avolio to analyse the relationship between supplier performance and leadership. We differentiate four different supplier leadership styles:
- Management by Exception
- Contingent Reward
- Transformational Leadership
All four leadership styles were represented in our study. Figure 1 shows the spread of different leadership style across study participants.
So, how do these leadership styles impact performance?
Figure 2 shows the difference in supplier performance between organisations which frequently use a particular leadership style versus those who don’t. Transformational Leadership has by far the biggest impact on supplier performance. It lifts the average satisfaction with the supplier from 6.0 to 7.6 out of 10.
In fact, the 26 study participants who received the highest performance from their suppliers were 29% more likely to use Transformational Leadership and 33% more likely to use Contingent Reward than the 31 participants reporting the lowest supplier performance.
Why Transformational Leadership works
Transformational Leadership influences supplier performance in four key aspects. Figure 3 shows that keeping up a high level of motivation and spending time on developing suppliers based on their individual needs have the biggest impact on results.
What’s more, suppliers managed by transformational clients go beyond what is required in the contract. Inspired by their client’s leadership, they go out of their way to deliver the best possible results.
As you can see from the study outcomes, your leadership style has a significant impact on the results you can expect to receive from your suppliers. Luckily, changing the way you manage suppliers doesn’t have to be hard.

 It is also the only style for which this impact is of statistical significance (at the 99% level). We have grouped Management by Exception and Laissez-faire due to the low number of respondents using them.
