Consulting - Crossing the boundaries

Have you ever amazed when you complete assignment/task/project work which you originally thought are complicated to accomplish or by no means doable for you? I had similar experiences. What is the rationale that one crosses his individual boundaries? Underrate capabilities? If your answer is yes then I think different.
I don’t think we underrate capabilities. I think, there are two reasons for this to happen. One is, we are on continuous learning process which increases our capability to do more. Other is, with structured approach. With structured approach we can even solve seemingly complex problem. This means, we do not require exact skill to solve the problem but we need the approach. This is nothing but fundamental premise of big consulting organisations. They take something which is complex to tackle, something in which they do not have experience in and with right approach they solve the issue. Now, here word “Solve” is very subjective. Solve does not mean best solution. It means solution. This is true when you do not have reference to compare the solution with.
I feel, consulting companies compete on the basis of approach. Approach is mix of experience, knowledge, information, creativity and gut feelings. I tend to think approach as “Skill” which is above particular subject and difficult to quantity. Skill is an individual attribute and not an organisational attribute.
Next time, Give it a thought when you take something challenging!!!
