What ever it takes to execute a project whether it is a fixed bid or Time and material based what matters is how you are managing your finances in terms of billing. Lets take a closer look to difference between fixed bid and time and material based project. 

A fixed bid project is the one which is having a fixed budget from client and defined set of scope. So, in a fixed bid project the ball is in your court. You define how efficiently you can manage on resources to utilize them fully to balance on your margins. There is other side of the coin also by having a scope creep if you really blow up your work. Obviously a fixed bid project later can managed by the delivery team and driven by project team.

While a time and material project is like a billing of resources involved on hourly basis for actual worked performed with agreed on terms and conditions. Also here one can get reimbursement for overheads.
Here there is one possibility of getting paid for scope creep of your project, so changes in scope will result in more billing , which in will result in more revenue.

So before giving estimates you actually think about whether its a Fixed bid or a T&M based project because fixed bid is fixed one has to live by the fixed amount budget whatever it takes to do it. In that case there is always a possibility of scope creep by having a change in requirements. So keep updating your estimates on regular intervals as requirements changes, to acknowledge of customer.

Because at the end of the day its important to get paid for your work and resources blocked for the same.

A common comic mail circulates with this image, which gives good understanding of how requirements captured during a project life cycle goes like this: Typical Software Development Life-cycle explained Above picture succinctly tells about common perception of developing a software, how requirement understanding filters with changing roles, time and space with gaps between factual and results. Thanks to the  the word "agility", which has evolved in world of software technology with the evolution of Rational unified process the term use-case or scenario development for documenting and capturing requirement in the initial phase of software development.

Understanding Business Value of IT(Information Technology)

Is IT driven by business? I believe its a good question to be asked at this point in time after the doom of financial markets allover world. When top investment banks collapsed in USA and Europe everybody is asking a question how it is possible if the system in place. IT in general supposed to be driven by business requirements so its natural process that, as other component in business, this is also adding value to business, but is that benefits realized to business? Is IT a hype from time and again? Business value of IT measured in different metrics and methodologies that may or may not give true picture of IT value to business, so the contradiction lies in the hypothesis itself that IT is driven by business which is adding no value but continuing. In the concurrent world where businesses are competing for survival and existence IT is invaluable from intangible perspective.  Making sense of PM triangle  The infamous scope, cost and schedule trio can be realized for IT bus...
