Tips to Reach Six Sigma










Comments

For the longest time, I was not aware of the intent of six sigma processes. Only recently have I stumbled across that the definition is plus or minus three sigma, like in the classic bell curve.

Internet is harmful for you: Google thinks so

Today, for a few minutes Google suddenly started warning all of its indexed sites as Harmful to your computer! Perhaps it was a glitch in their algorithm, but we managed to make a snap of it for the record.

Cyclomatic complexity

Cyclomatic complexity is a software metric (measurement). It was developed by Thomas McCabe and is used to measure the complexity of a program. It directly measures the number of linearly independent paths through a program's source code. It is computed using a graph that describes the control flow of the program. The nodes of the graph correspond to the commands of a program. A directed edge connects two nodes if the second command might be executed immediately after the first command.


Definition

M = E − N + 2P

where

M = cyclomatic complexity
E = the number of edges of the graph
N = the number of nodes of the graph
P = the number of connected components.

"M" is alternatively defined to be one larger than the number of decision points (if/case-statements, while-statements, etc) in a module (function, procedure, chart node, etc.), or more generally a system.

Separate subroutines are treated as being independent, disconnected components of the program's control flow graph.


test coverage matrix vs traceblity matrix

Test coverage matrix:

Test coverage matrix is a checklist which ensures that the functionality of the given screen(unit) is checked in all possible combinations (positive and negative) which have not been covered in test cases. Test coverage matrix is usually prepared for a screen having large number of controls (textboxes, dropdowns, buttons etc) usually, test coverage matrix is prepared in a spread sheet having all the controls (textboxes, dropdowns, buttons etc) in the columns and then all possible entries in those fields in the rows with an ''yes'' or ''no'' in the rows against the controls listed in the columns. For example, consider a ''login'' screen wherein we have ''username'' and ''password" textfields.

While preparing test coverage matrix, the first column will be ''s.no'' and the second will be ''username" and ''password" will be the third field followed by …
