Why is the SLC needed?
 

As was mentioned in the previous page - change is risky.

IT change is particularly  risky!

Consider the sobering results obtained from a survey of over 14,000 organisations (OASIG study):

bullet

80-90% of systems fail to meet performance goals

bullet

80% of systems are late and over budget

bullet

40% of systems fail or are abandoned

bullet

Less than 40% of businesses fully address training and skills requirements

bullet

Less than 25% properly integrate business and technology objectives

bullet

Just 10-20% of businesses meet all their success criteria.

Therefore only between 1 in 5 and 1 in 10 of the IT projects in the survey were successful.

What could have been done better?

What could reduce the chances of failure?

As people have learnt from past mistakes, a model has been developed and refined over the years to try and maximise the chances of a successful project.

This method / model  is called the SYSTEMS LIFE CYCLE.

It consists of a series of stages that take a project from its very first stages to the final outcome of a fully working, fully integrated system.
