Struggles with similar businesses and businesses in different industries are similar except which level the struggle happens on. For this reason I have grouped the possible problems together.
All struggles develop from a change in the Physical Environment (Primary Struggle). When businesses start to adapt to these changes they create a Ripple Affect which creates struggle for other businesses (Secondary Struggle). The way you deal with these two problems is different. Finding your struggle is the first step to succeeding; next find out how to deal with it. (This is not an exhaustive list but it will give you an idea to start from)
