How to Select the Analytical Method
In Chapter 3, we performed a so-called strategy mapping process (i.e., we presented a method where we had some strategic objectives and ended up with having some specific information requirements). Now, we will pick up this thread. We will perform an information mapping process,
Exhibit 4.2 The Three Imperatives in Connection with Choice of Methods and Information Mapping
where we start with some specific information requirements and proceed to identify which specific analytical techniques will deliver the required knowledge or the desired information.
The aim is to present a model that can be used in the dialogue between management, who wants information, and the analyst, who must deliver it. In the introduction to this chapter, we said that we would be delivering a menu. What we want to deliver here, too, are some key questions to ensure that the dialogue between analyst and recipient provides an overview of how this menu is designed to facilitate the right information being ordered. More specifically, this means that we divide potential BA deliveries into four information types (see Exhibit 4.2), deliver the questions that will help clarify which information types are the most relevant, and go through the four information types one by one. Concentrate on the type that is relevant.
In terms of perspective, we start with a business perspective and finish with an analytical perspective. We begin, for example, by requesting information about which customers will be leaving us in the next month, and finish, perhaps, with the answer that a neural network will be a good candidate in terms of selecting a method of delivering results. The business-oriented reader who wants to understand more about scalability levels, say, can log on to BA-support.com, where we have included an interactive statistics book, along with a number of examples and case studies, as well as contact details for the authors of this book.
