Usecase Scenario development and User Stories

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.

"A use case is a software artifact of systems and process of expected sequence of interactions between a module and an external actor, which leads the actor to desired goals and objectives."

Use case scenarios can be mirrored as clip of a movie making scene development where-in director has assigned a script or stories to actors to act in the dialog delivery with lights, camera and action that's called a TAKE.

On the very same lines we have User Stories which can be a powerful tool to be converted into a Use-case scenarios. User Stories can be categorized into user needs, wants and demands from usability perspective of the system development.

Definitely Use cases are key building blocks of any software development life cycle which is again powered by user stories. It is well known fact, mislead requirement will lead to many gaps created in early part of project to be rectified at each cycle of the project in later phases of the project.

Porter's outside-in and Hammel - Prahald's Inside-out

Over the years inspiration and motivation to out do something which creates spark in the genre of concurrent times is always been challenge for all of us, to make things happen requires a plan, an out of the box solution to rationalize its existence. More often than not inspiration are unknown to us, which may leads to different scenarios of multiple ways of looking at things differently and indifferently also, anyways there are always n-1 degrees of freedom to think differently for n+1 different ways looking at things. Inspired by a spiral which is coincidentally a galaxy in our spatial system gives us views like --if one start from a point from outer end to reach at center, will reach from outside-in and if one starts from the center and circle outwards move than that will be inside-out thinking. So again its up to individuals, which way move. Traveling by we see stars and other objects binding each other with gravitational forces. Galaxy One of the many management stra...

Games People Play in context to Projects

Games People Play in context to Projects: Contextually life and projects full of games, work on dynamics of human relationships by Dr. Eric Berne guides us not only in many social but relationship situations in corporate world also. In Todays concurrent world where we are living in a global village with Orkut, Facebook, Linkedin, Twitter and other social media leads to discounts of information in social network, where more of transactional games played knowingly(conscious) or unknowingly(unconscious). Precede to this let us understand game, A game full of transactions played with different roles by players changing their roles for a outcome in different ego states like Parent, Adult and Child ego states that will payoff. Continuing with Payoff, specifically in context to Project teams where transactions happen at concrete or transformational levels where people not necessarily behaving rationally and motivat...

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...
