Moving from personal to impersonal language

An example of the type of personal writing to avoid in academic writing:

I believe that the "Design School Model" is a good basic model, yet from reading the related arguments and coming to my own conclusions, I feel that the model is flawed because there are many factors to be considered before a business is even ready to do a successful SWOT analysis, let alone using it solely for the formulation of strategy. Therefore I must conclude, based on the beliefs of Mintzberg, Ansoff and myself, that the "Design School Model" is not a solution to the problem of formulating strategy.

The use of personal pronouns and judgemental words in this text results in a clear expression of the writer's feelings. As a reader therefore, you become very aware of the writer's presence in this text. This characteristic is undesirable for most academic writing.
