How can Six Sigma be applied to software development?

[benchmarksixsigma]

Common Six Sigma project objectives in Software Development processes
are as
follows:-

o Reducing schedule slippages

o Reducing number of bugs being detected in the field during usage of
the
product.

o Reducing rework in requirements development process to incorporate
customer expectations

o Reducing time and cost overruns in project planning phase due to
inaccuracies
in the estimation process

o Increasing defects detection early in the process so that costs are
less
compared to defect dtection later in the project.

o Reducing or eliminating invoicing errors

o Reducing rework (All work done to fix an application after it has
been
delivered to a customer is rework. This includes corrections to
features or
functions that are incorrect, and also may include "missed
requirements" –
things the customer expected but did
not receive.

o Reducing Customer complaints

o Reducing complaint resolution time

o Improving defect containment effectiveness (DCE)

o Reducing appraisal cost per defect by phase and appraisal type (by
project and in total)

o Reducing effort variance normalized by size.

o Improving the efficiency (conversions) in sales processes.

o Improve the forecast accuracy
