At Wiztech Inc., we adopt the Spiral Progressive Approach to deliver a project.
The salient features of this approach are:

• It follows an Iterative Development model
• Development phases are revisited with a feedback loop from forward stages at the end of each critical milestone.
• At one particular time, all disciplines of each project is active.
• The active percentages of each discipline are different, depending upon what phase we are currently focusing. This is equivalent to saying that at one particular time we will doing.

The main benefit of this approach is that the customer can always see how the project is shaping up, not like a waterfall approach where a customer sees projects only after one phase is complete. This process reduces the time needed to make corrections.
