True Agile - Principle - Working Software
Working software is the primary measure of progress.

It says that the outcome is more important than the process at any point of time.
The basic measure of progress is measuring things that are finished. Software is finished when it is successfully tested and delivered.

The way to measure progress is to measure the amount of work to-be-done. For every sprint or iteration, the team agrees upon a certain backlog of work. This is the amount of work that the team thinks it can deliver in the sprint. The amount of work to-be-done is the backlog. This can be measured at any time during the sprint.

When you plot the amount of work to-be-done on a day to day basis you will get a good overview of the progress. This is called a burn down chart. The velocity is the measure of the productivity of the team and helps the team to improve the estimation of the next sprint. The beauty of this method is that it is continuously evaluating.

The principle emphasizes that the only suggested way to measure progress is “Working software”. This is the only point the end-user is able to measure the progress of the development team. Working software is defined as tested software that delivers value to the end-user. Good test-scripts and test-data are crucial in supporting this process. These test scripts can also be used for (regression) test automation.

During the sprint (or even the project) you can measure progress by plotting the work to-be-done in a burn down chart. The improvement of the team’s performance can be measured via the velocity.
