Interconnected DevicesUniversal usage (Business,

Governance, Retailing, Utilities, Education, Automotive, Scientific, etc…)

Why past ?Once upon a time… Now…

Scientific and Defense Universal Application

Small groups of engineers; experts in everything

Large teams specialized in work areas

Geographically less dispersed teams

Distributed teams in norm

Procedural and Structural Programming

Functional and Object Oriented Programming

Low level programming / Machine code

High Level Programming with higher abstraction

IDE EvolutionIBM Punch card machineTimesharing terminalTurbo Pascal (simple text menu screen, Wordstar-like editor, the

Pascal compiler, runtime library, run in memory and compile to disk)

Visual Basic, Delphi (allowed you to create forms by

dragging and dropping pre-built components.  The components/objects contained properties, methods and events.)

Eclipse, NetBeans (programmable editors, code

refactoring engines, team collaboration systems, object and data modeling, build environments, debuggers, unit testing and static and dynamic analysis)

Possible Solutions

Possible Solutions All the requirements should be at one place; I am happy to see the high level

requirements.

I want to have the traceability of the code (irrespective of a feature, improvement, bug or a task)

I would like to have the transparency of the tasks that i am working on

Each time a task or on issue is taken care of, i should be able to decrease my product backlog 

Should be able to do all the CM related tasks (Locking, Branching, Merging, Diff, etc…)

Each commit that i do should be able to notify my team and managers by mail

I don’t want to be micro-managed. My manager should be able to get all stats that he wants by tools that use

I want to manage my release plan in a single tool and be seen by Developers, QA, Product Team, Customers, in short all my project’s stakeholders.

For a simple reason that SW Development deals with communication, i would like to have all the communication that happens on a requirement, features to be in a single place. I want to have a trail of all my threads or in other terms i want to have audit trail.

I should be able to know the load on each of my team members

I should be able to query depending on variety of parameters

For each release bucket, i should be able to know what % of tasks/work is completed

If yours is a CMM organization…. you have more requirements on the CM permissions, checkins, etc…

I should be able to get the release notes directly from a tool so that i can reduce my manual work in compiling the tasks, bugs, improvements and enhancements.

…. many more …

Possible SolutionsIndependent of SCM that you useIndependent of IDEs (?)Process IndependentA platform that any tool vendor

can provide tools on

We need a Platform; Not just an IDE.
