Vision, by the word itself, is the way you see a particular abstract construct as it moves through the market of ideas.

A project always starts with a defined vision. From the abstract vision, we slolwly develop the model that we will use in order to execute the plan. Strictly speaking, the vision always comes first. Usually, the common mistake is to immediately construct the model. Well, this is a fatal one if you ask me.

Vision, by the word itself, is the way you see a particular abstract construct as it moves through the market of ideas. The initial thread from which your vision moves is determined by either your learned knowledge or gained experience. Thus, limited learning or real life immersion tends to yield limited vision.

The Model, on the other hand, is the by-product of the vision. It is the physical representation of the motivation behind an abstract construct. In a way, it is the language formed by an individual to communicate a vision that is often personal in meaning and structure. If the model is unable to communicate the vision, then execution becomes a big problem.

That is why, it is vital to determine the parameters of the model. These parameters determines the language, the tone and the mode of communication. If the parameters are not properly handled, a creative team usually end up with a non-communicating entity which is troublesome when we are required to deploy such model to a wider market.

For me, both vision and model are equally important. Though the vision always comes first before the model, still, if the model is weak, no matter how strong the vision is, it will find it hard to engage the immediate stakeholders and the eventual end-users
