Quality vs. Speed -- The Agile Way

There has always been a debate over producing a quality application versus an application that is delivered on time.  Indeed, even within the quality camp there are divisions over what exactly constitutes quality.  There have been efforts in the past to merge quality and speed of delivery so that you can get a high quality application in as short a period of time as possible.  The Agile methodology tries to merge these two, to mixed results.

Why mixed results?  Like everything else in life, more than just how you do something determines the end result.  In the case of the Agile methodology (or should I say methodologies) there is more than one way to skin a cat.  The Agile methodology is so different from what people were taught in school that there are three large stumbling blocks that need to be overcome in order for Agile to be truly effective.

• Organization.  There are forces at work in an organization to keep things moving forward.  Plans need to be made, followed and tracked.  The agile methodologies have the idea that "responding to change over following a plan" is a better way to develop software.  And, while I personally believe this, organizations tend to want plans.
• Team. While Agile has come up with some basic philosophies behind how to develop software, the larger the team the more unlikely it is that these philosophies will be effective due to outside pressures: when is going to be done? It is difficult for project managers as they are measured on progress.  Agile, because of its fundamental desire to respond to change, is havoc on plans, at least traditional "we will have this functionality delivered by that date" type of plan.
• Individuals. Everyone comes to a project with baggage:  their old projects and the "we did things this way" ideas.  Getting everyone on the same page, following the same ideas and concepts is very difficult. 

This is not to say that Agile will not work and that you will produce a quality application in less time.  The problem lies in being able to show somebody that this will happen.  Without a proven track record it is hard to show people that it will work, but you need that acceptance so that you can build that track record.  And without the right people in the right places, Agile is never going to fully accepted, fully understood or fully implemented.
