Even the best marketing strategies need to be revisited, if not revised. Changes in the market environment can dramatically change the marketing mix and your product plans. Marketing strategy should be viewed as a process, which means that the best laid marketing plans will change sooner or later.
Strategic change can be caused by many forces; sometimes change is a threat while other times it can be an opportunity. It all depends on how your product or business is defined; additionally, how you react may be the largest factor in your future success.
Sometimes the market evolves and the demand for an offering changes. For example, obesity is on a dramatic rise in North America; because of these people are becoming more "food label savvy" about calories, fat grams, sugar, carbohydrates, and protein. Fast food restaurants have had to respond with salad bars, better disclosure of nutritional information, and leaner products.
Another source of strategic change is technological innovation. As microprocessors increase in speed and processing ability, older personal computers quickly become obsolese. A more disruptive technological change might be the creation of the MP3 format and downloadable music. Music is now purchased one song at a time instead as albums of songs.
Occidentally, a market is redefined. This is often driven by competition or customer demand. Today, our fast paced culture demands a more personalized relationship with information, which has created wikis, blogs like this one, and the birth of IPTV (Internet Protocol Television). This new information content business allows the reader or viewer to get "personalized content" when they want it and where they want it.
Also, marketing channels change. Today the internet has changed the relationship of customers with providers. No longer dependent on the provider for education on products and services, the new consumer is more informed and sophisticated than ever. In fact, the consumer is more powerful and will get what they want or they will find another provider.
For the marketing strategist, the challenge is to anticipate the changes and take control of their destiny. The alternatives of delaying action or getting surprised can mean business failure.
