– Service activities are those that maintain and enhance the product’s value including customer support, after-sale services, etc.

Primary activities may be vital in developing a competitive advantage. For example, logistics activities are critical for a provider of distribution services, and service activities may be the key focus for a firm offering on-site maintenance contracts for office equipment. These five categories are generic and include specific activities that vary by industry.

Support Activities

The primary value chain activities described above are facilitated by support activities. Porter identified four generic categories of support activities, the details of which are industry-specific:

– Procurement – the function of purchasing the raw materials and other inputs used in the value-creating activities.

– Technology Development – includes R&D, process automation, and other technology development used to support the value-chain activities.

– Human Resource Management – the activities associated with recruiting, development and compensation of employees.

– Firm Infrastructure – includes activities such as finance, legal, quality management, etc.

Support activities are often viewed as «overhead», but some firms successfully have used them to develop a competitive advantage, for example, to develop a cost advantage through innovative management of information systems.

Value-Chain Analysis

In order to better understand the activities for a competitive advantage, one can begin with the generic value chain and then identify the relevant firm-specific activities. Process flows can be mapped, and these flows used to isolate the individual value-creating activities.

Once the discrete activities are defined, linkages between activities should be identified. A linkage exists if the performance or cost of one activity affects that of another. Competitive advantage may be obtained by optimizing and coordinating linked activities.

The value chain also is useful in outsourcing decisions. Understanding the linkages between activities can lead to more optimal make-or-buy decisions that can result in either a cost advantage or a differentiating advantage.

The Value System

The firm’s value chain links to the value chain of upstream suppliers and downstream buyers. The result is a larger stream of activities known as the value system. The development of a competitive advantage depends not only on the firm-specific value chain, but also on the value system of which the firm is a part.

PEST Analysis

A PEST Analysis is an analysis of the external macro-environment that affects all firms. PEST is an acronym for the Political, Economic, Social and Technological factors of the external macro-environment. Such external factors are usually beyond the firm’s control and sometimes present themselves as threats. For this reason, some say that «pest» is an appropriate term for these factors. However, changes in the external environment also create new opportunities and the letters sometimes are rearranged to construct the more optimistic term of STEP analysis.

Many macro-environmental factors are country-specific and a PEST analysis will need to be performed for all countries of interest.
