(b) Divestment of products or parts of the business is one of the most difficult strategic decisions. As apparent in Bonar Paint a
reduction in the products and customers served by the firm is likely to cause significant changes to the firm’s value chain and
system. Currently Bonar Paint supplies its customers, regardless of size, directly and this inevitably means that their
distribution costs are increased. The reduction in products and customers may allow a choice to be made about the costs of
supplying customers directly as against using distributors to handle the smaller customers.
In using the value chain one is looking to identify the significant cost activities and how those costs behave. Some costs may
be affected by the overall size of the firm e.g. advertising while others affected by the batch size being processed. The changeto fewer products will lead to a bigger batch size and a number of positive consequences for costs. The value chain’s major
benefit is in identifying and quantifying the links that exist between various activities within the firm and between the firm
and its customers and suppliers. In Bonar Paint’s case does a reduction in product range lead to less product failures and
consequent warranty claims? Does simplifying the product range lead to shorter lead times and better delivery time
performance for its customers? Above all, a good understanding of its value chain will let it know if it changes an activity what
are the consequences for other parts of the system.
In terms of reducing the product range, before such a decision is taken Bonar Paint must carry out a thorough analysis of the
pattern of customer demand for each paint type. In all probability it will find that 80% of its sales come from 20% of its
product range. Having given this qualification, reducing the product range can have a number of beneficial results on other
parts of the value chain. The immediate effect is likely to be that Bonar Paint produces fewer batches over a given time period
but produces them in larger quantities. This will bring cost savings but the impact on other parts of the value chain is equally
important. The beneficial effects are:
– With a smaller product range the control of raw materials and finished inventory will be simplified affecting inbound and
outbound logistics. This will improve the inventory turn and make for better product availability.
– With an improved inventory turn this will reduce the firm’s working capital needs and release significant amounts of
cash.
– A simpler operations process should facilitate staff savings and support more automation.
– Warranty claims and support costs could be reduced.
– Bonar Paint will be purchasing fewer raw materials but in greater volume and on a more regular basis. This will lead to
improved price and delivery terms from its suppliers.
– Bonar Paint can offer improved product reliability and better delivery to its customers and should improve its market
share.
In terms of operational disadvantages, these therefore are largely in terms of the impact on customer service levels seen in
terms of product range availability. Once again it is important to have accurate information on the sales and profitability of
each product so informed divestment decisions could be taken. Care must be taken to identify any paints, which though
ordered infrequently, and in small quantities are a pre-cursor for customers ordering other paints. Some important customers
may require that the full range of their paint needs are met in order to continue buying from Bonar Paint.
Reduction of the product range and customer base is an important strategic decision. Eliminating non-contributors or ‘dog’
products both in terms of paints and customers is a key part of managing the product portfolio. However, inertia both in terms
of products and customers is a real strategic weakness. In terms of the three tests of suitability, acceptability and feasibility
the analysis suggests that only acceptability is likely to be an issue. Tony Edmunds needs to be convinced that it is an
appropriate strategy to adopt. It is the lack of accurate sales analysis that lies at the heart of the problem and that is his areaof responsibility!
