SITARA Continuing Education
Points: 1 points
TUTORIAL DURATION : 1 Day
PREREQUISITES:
Understanding the use of Statistical Process Control Techniques
TUTORIAL OBJECTIVES:
Participants will understand the method that has to be
employed to determine process capability of a
software process through hands-on practice sessions.
Definition of two of the most intriguing terms: Defect and
Critical to Quality Characteristics as applicable to
software will be elaborated in the tutorial
ABSTRACT:
This tutorial describes the
approach that should be adopted while determining the process capability
of the software development process. In simple terms: the Sigma Capability
of a process is known by first quantifying two numbers, determining a
ratio between them and then reading off a table that maps this ratio to
the sigma equivalent. But, are these two numbers - one, the number of post
release defects and two, the number of critical to quality characteristics
subject to individual interpretation?
Further, since the ratio is defined as the number of post release defects
to the number of critical to quality characteristics (CTQ), and it is
after all human to err, the number of defects become inherent to the
process due to common-cause variations of the process after a point.
Therefore, if the number of CTQ is increased it is theoretically possible
to arrive at a fantastic process capability that is much closer to the 6
sigma level of perfection! But, what is the right way to do it?
The purpose of this tutorial is to establish a proven way of knowing these
two measures - the number of post release defects and the critical to
quality characteristics. Emphasis of this tutorial will be to provide a
technically sound definition and understanding of the method that should
be employed to determine the process capability in statistical terms after
first, defining the terms "defect" and "critical to quality
characteristic".
The day-long tutorial will describe the essential technical and management
processes that must be built into the measurement program to ensure that
phase-wise process capability is tracked and measured. It will expand on
this topic and show with examples as to how the final process capability
of a software development process should be arrived at for it to be
termed-technically correct.
Should the sigma capability be known at every phase in the lifecycle of
the development process? The answer is, yes. Will the process capability
of the overall lifecycle, then be limited and restricted to the weakest
capability of a phase? The answer again is, yes. How many repeated cycles
of measuring the process capability be used to arrive at this statistical
number and how do I do it? Attend the tutorial!
