How to start implementing agile practices in your company ?

Implementing an agile method in your company may requires continuous and progressive changes to raise stakeholders commitment and culture to handle those new packaged practices ,thus you may start by implementing actions that have an almost direct impact on quality assurance issues and development life cycle to make your team more productive and rigorous through the release process. Here are some of the points you may start with, to help you going through:

Just in time and lightweight requirements:
Keep the requirement level at the minimum required to start the development process.

Automated repeatable unit tests :
Test must be integrated throughout the lifecycle, not at the end .Test scenarios should be written before the development starts (knowing that you would write them anyway!).

Software release must rely on customer feedback :
Don’t waste your time developing unusable functionalities that wouldn’t add any business value to your software; focus on getting the most important features and items first to the market. Make them prioritized to get the better of agility and flexibility.

Stick to a regular software release cycle:
Fixed release cycle (iteration, sprint) is vital, it creates routine (stakeholders, departments, team members) and routine increases productivity. At the end of each release, all features must be completely done and functional, this ensures a clear and complete vision toward the software development progress, reduced risk and higher value.

Get the best of your stakeholders:
By making them working toward a shared goal.

Remember, the success of your project is all about making your stakeholders happy :).
