In order to analyse the current business portfolio, the company must conduct portfolio analysis (a tool by which management identifies and evaluates the various businesses that make up the company).
Two steps are important in this analysis:
1. The First Step is to identify the key businesses (SBUs). The Strategic Business Unit (SBU) is a unit of the company that has a separate mission and objectives and which can be planned independently from other company businesses. The SBU can be a company division, a product line within a division, or even a single product or brand.
Three characteristics of an SBU
* Single business or collection of related businesses that can be planned for separately.
* Has its own set of competitors.
* Has a manager who is responsible for strategic planning and profit.
2. The Second Step is to assess the attractiveness of its various SBUs and decide how much support each deserves.
The best-known portfolio planning method is the Boston Consulting Group (BCG) matrix:
* Using the BCG approach, where a company classifies all its SBUs according to the growth-share matrix.
* The vertical axis, market growth rate, provides a measure of market attractiveness.
* The horizontal axis, relative market share, serves as a measure of company strength in the market.
Using the matrix, four types of SBUs can be identified:
* Stars are high-growth, high-share businesses or products (they need heavy investment to finance their rapid growth potential).
* Cash Cows are low-growth, high-share businesses or products (they are established, successful, and need less investment to hold share).
* Question Marks are low-share business units in high-growth markets (they require a lot of cash to hold their share).
* Dogs are low-growth, low-share businesses and products (they may generate enough cash to maintain themselves, but do not have much future).
Generally, a SBU introduces a new product into a high-growth market, which will obviously have a low market share. The SBU has to do substantial marketing expenditure to increase the product's market share so that it becomes a "star" product. When the industry growth rate again declines, the SBU generally stops all marketing expenditure on this product which gives the SBU lot of cash as the expenditure is substantially reduced while the revenue is still very high. This surplus fund generated by "cash cows" are utilised for development of new products and establishing these new products in the market.
Once it has classified its SBUs, a company must determine what role each will play in the future.
The four strategies that can be pursued for each SBU are:
1. Build: Here the objective is to increase market share, if necessary, even foregoing short-term earnings to achieve this objective.
2. Hold: Here the objective is to preserve market share.
3. Harvest: Here the objective is to increase short-term cash flow regardless of longterm effect.
4. Divest: Here the objective is to sell or liquidate the business because resources can be better used elsewhere.
As time passes, SBUs change their positions in the growth-share matrix. Each has its own life-cycle.
The growth-share matrix has done much to help strategic planning study; however, there are problems and limitations with the method.
* They can be difficult, time-consuming, and costly to implement.
* Management may find it difficult to define SBUs and measure market share and growth.
* They focus on classifying current businesses but provide little advice for future planning.
* They can lead the company to placing too much emphasis on market-share growth or growth through entry into attractive new markets.
This can cause unwise expansion into hot, new, risky ventures or giving up on established units too quickly. In spite of the drawbacks, most firms are still committed to strategic planning.
