Why SCRUM

We have taken project management from the building industry where 90% is a known factor and 10% is unknown.

And introduced it into an industry where 90% is unknown and 10 % is known.

In the building industry, there is a project manager who has all the knowledge, setting schedules and committing to the client

In the software business the project manager has the least knowledge of what it takes setting schedules and committing to the client

So 90% of software development projects are over time and over budget.
