Information technology consulting (also called IT consulting, computer consultancy, computing consultancy, technology consulting, business and technology services or IT advisory) is a field that focuses on advising businesses on how best to use information technology to meet their business objectives. In addition to providing advice, IT consultancies often estimate, manage, implement, deploy, and administer IT systems on businesses’ behalf, known as outsourcing.

The usual problem is that a business owner doesn’t know the detail of what the project is going to deliver until it starts the process. In many cases, the incremental effort in some projects can lead to significant financial loss

The scope of a project is linked intimately to the proposed business processes and systems that the project is going to deliver. Regardless of whether the project is to launch a new product range or discontinue unprofitable parts of the business, the change will have some impact on business processes and systems. The documentation of your business processes and system requirements are as fundamental to project scoping as an architects plans would be to the costing and scoping of the construction of a building.

The most successful business projects are always those that are driven by an employee who has the authority, vision and influence to drive the required changes in a business. It is highly unlikely that a business owner (decision maker or similar) will realize the changes unless one has one of these people in the employment. However, the project leadership role typically requires significant experience and skills which are not usually found within a company focused on day-to-day operations. Due to this requirement within more significant business change projects/programs, outside expertise is often sought from firms which can bring this specific skill set to the company.
