Our category approach and delivery models Our category approach and delivery models

Overview of our category approach and delivery models we use to engage with our suppliers.

Category Management

Our category approach

We have adopted a category management based approach to procurement, which acknowledges a combination of organisational structure, the uniqueness of individual category requirements and supplier markets. This will also aid us in focusing on an ‘all of business’ cross functional approach to procurement rather than a siloed approach.

The procurement categories described below form the basis for the development of Procurement Category Plans and the reporting of spend data.

Category positioning is a way of understanding how important each procurement activity is to AT, and how important AT might be to potential suppliers or providers in the relevant supply market.

The category positioning matrix assesses the strategic importance, business impacts and risks in delivery against relative value. It is a useful tool to help inform the approach to market, the type of relationship to be developed with the supplier/s and consideration of key outcomes from the procurement process.

Each procurement opportunity will be strategically assessed to identify which of these positions applies and will be documented in both overarching Category Strategies and individual procurement plans.

Procurement delivery models

A delivery model is the relationship established between Auckland Transport and a supplier to enable the purchase of the output required to deliver an activity. Each delivery model has a different approach to contracting, work methods and risk allocation to suppliers.

In selecting the appropriate delivery model, we will assess the activity against the following criteria:

  • Complexity
  • Evolving and Future Category Developments
  • Innovation potential
  • Scale
  • Risk profile
  • Timing and urgency
  • Supplier market
  • Stakeholder requirements
  • Uncertainty
  • Level of our involvement
