Getting Ready for
Product Configuration Management (PCM)

Many companies have a large catalogue of different manufacturing and purchase parts and components they use whenever one fits into a new product. It’s a lot like a large box of Legos, where one searches as long as required to find the right piece. But unlike playing with Legos, where one is limited to the pieces in the box, if an engineer doesn’t find a fitting part within a reasonable time, they quickly move to design a new one, with usually very expensive consequences downstream.

It would be much easier, faster and less costly if a product could be configured using a limited number of preconfigured modules, like for example a few different motors, batteries, bodies, chassis, drive trains, wheels, interior configurations, entertainment systems, etc. for which it has already been determined how they fit and work together.

And that is where a majority of the preparation effort is to make product configuration management work:

a) Analyze all existing products, identify what parts are common or can and should be reused across different products. Generally the more the same part can be reused across different products the cheaper the part as a result of economies of scale.

b) Define platforms or models. For example an economy model, a sports model, a family model and a truck.

c) Define modules that can be used in all platforms, like motor, battery, body, chassis, drive train, wheels, front seats, back seats, etc;

d) Define variants and options for each module. For example 200 kW motor, 260 kW motor and 320 kW motor; sedan, coupe, station wagon, convertible and truck; short chassis, medium chassis and long chassis; steel wheels and alloy wheels; textile seats or leather seats; sunroof or moonroof; a Pioneer, a Bose or a Sony entertainment system, etc. A variant thereby is something of which one has to be selected for each configuration, whereas an option is something that can or cannot be selected. For example, wheels are a variant, because one type of wheels have to be selected for a product. The sunroof and moonroof are options, because any car model could be ordered without it.

e) Define configuration rules that define which variants and options can, cannot and should be used together and with which platform or model. This is where it can get complicated, as with an increasing number of different modules, variants and options there is an exponentially increasing number of possible combinations and permutations. For example 3 different modules with only 2 variants or options each already results in 9 possible end configurations, if everything can be combined with each other. So it is generally important to keep the number of modules, variants and options as low as possible and define rules that limit what can, cannot, should and should not be used together. For example, it may be technically possible to configure the truck with a 200 kW motor, but we may not want to sell this configuration because the truck would not be powerful enough. But it may not be technically possible to configure the small car with the most powerful motor because there is not enough space. Another rule may be that the short chassis can only be configured as a coupe and station wagon, and the truck can only be configured with the medium and long chassis. Then of course for all models the sunroof and moonroof can be selected as options, except of course for the convertible, where a sunroof and moonroof make no sense.

Once all the models, modules, variants, options and configuration rules are defined, a determination needs to be made if existing products should be reconfigured using the new setup. If the existing products are still being sold, it most likely makes sense. If the existing products are just being used in the field, but no new models of this type are being sold anymore, it probably does not make sense and the new approach should just be applied to new products that are being sold.

This reconfiguration can involve significant effort as existing CAD assemblies and EBOMs may have to be restructured to reflect the new product configurations with the defined modules, variants and options.

Another important step is to define guidelines how models, modules, variants and options are used and when new ones can or should be added.

The reason is that it is usually easy to sell a new product that deviates only slightly from an existing one. But the downstream consequences are usually dear. So what should be done if a customer asks for a slightly different product then what is available. In our case, what if customers repeatedly ask for a Denon sound system? Should the company say no because that’s not an available variant? Should the company handle these instances as exceptions and custom configure the product with what the customer wants, in deviation of the existing variants and options? Or should a project be initiated to add a Denon sound system as a new variant?

There is not a right or wrong answer to these questions. But these are business decisions that should be made before the situation arises. Because in an urgent situation, one may make a decision that has long-lasting and expensive consequences.

In summary, implementing a new product configuration management solution involves a significant preparatory effort to define new models, modules, variants, options and configuration rules, and to apply them to the existing products. This effort can take many months and require many resources and should therefore be very carefully planned.
