The first part of any sales process is to identify prospects that have a problem you can solve. The more pressing the problem, the more valued will be the solution. It is also very important to identify time points, because other wise you may identify an important problem that no one is in a hurry to solve, even if you have the best solution.
This can be on a number of levels and each business may have a number of sales processes, each related to the same or different prospects, including new business, cross-sale and up-sale. In each case, identifying who are the targets for each proposition is crucial, because only then can you begin to direct your prospecting resources with precision, and quantify the performance and return on investment for each prospecting activity.
For Business to Consumer (B2C), Search Engine Optimisation (SEO) and Instagram are great tools, whereas for Business to Business (B2B) then Target Account Selling (TAS) is often more appropriate.
In all cases, it makes it much easier to hit a target, when you are clear which targets you want to hit.
