Systems, Modules or Components? New Light on Purchasing

However, this bigger mandate could interfere with value-creation opportunities from other suppliers -- such as a brake system supplier that can integrate the functions of the foundation brakes with the actuation hardware and the increasing electronic content of anti-lock brakes.

As Exhibit IV illustrates, a brakes system supplier can create significant value by designing the system as an integrated whole. As this example shows, a major challenge is choosing between boundaries defined by "functional system specifications," like brakes, and those defined by "physical boundaries," which describe modules delivered to the customer as a single subassembly, like the rear axle.

EXHIBIT IVCHOOSING CORRECT BOUNDARIES

Both options provide broader boundaries for suppliers, opening up more opportunities for value creation. However, the overlap between these boundaries creates confusion, and often "systems" and "modules" choices are mutually exclusive.

Conclusion: How to Move Forward

To avoid these pitfalls and move toward optimizing a company's extended enterprise of suppliers, our research suggests following a structured five-step methodology.

This robust, iterative process starts with:

1) The economic decision as to how to create the most value.

2) From there it defines supplier capability requirements.

3) It also identifies the appropriate suppliers that can manage the given scope.

4) To deliver the results, the methodology deals with the specific tactical decisions about how to structure the best working relationship with the suppliers.

5) To insure continued and sustained results, it provides a performance-monitoring system to drive improvement. (See Exhibit V.)

EXHIBIT V FIVE STEPS TO SUCCESS

The methodology also has many feedback loops that force a revisiting of the scope boundaries question, based upon the current supply capabilities and strategic imperatives. A paper entitled "Suppliers in the Innovation Stream" (to be published later this year as a Booz-Allen & Hamilton Viewpoint) describes the methodology in more detail.

Scope boundary definition is complex, because of the difficulty in quantifying value creation and in managing trade-offs. Furthermore, the "optimal" boundaries are constantly shifting, as new functionality is added to the end product and new technologies provide innovative solutions.

Nonetheless, understanding and optimizing the boundaries are critical first steps in capturing the full potential of the extended enterprise of suppliers.
