Some aspects of supplier performance cannot be ascertained by asking them, as they may not be aware. Gordon (2008) states that a lot of insight is needed into not only supplier performance using quantifiable performance metrics but also the means by which this performance is achieved. This includes the supplier's processes, practices, behaviour and culture. However, if we accept that by forging the right relationship with certain important suppliers we can add value, then it follows that we must also measure processes, practices, behaviour and culture; theirs and those that are joint between us.
There are measures we can develop for aspects of process efficiency and effectiveness, but practices, behaviour and culture are much more subjective. In a close personal relationship norms around practices, behaviour and even culture develop. There may not be a specific discussion around this but in a healthy relationship practices get agreed based on what works for both, behaviour gets shaped through parties agreeing what is mutually acceptable and where boundaries lie and if all these things happen the relationship takes on its own positive culture over time. Split up and meet someone new and the process begins over. The same happens with a supplier relationship, except companies rarely seek to agree what practices and behaviours are appropriate or expected, yet if we do this we then create the basis to measure it or at least check it feels right. In Chapter 11 we will explore the Relationship Charter, a means to define expected practices and behaviours and thus a basis to them measure the degree to which parties emulate this.
Collecting and analysing data
KPIs typically demand different data types, from different sources. Collecting data to create KPIs could be an automatic process in real time, perhaps using a corporate system or well-designed app, or perhaps it requires a regular or even irregular activity to produce the latest set of KPIs. We could do this or we could get the supplier to do this, or a combination of both.
