%Cyclomatic complexity (CC) = E - N + p |
| 128 |
|
%where E = the number of edges of the graph |
| 129 |
|
%N = the number of nodes of the graph |
| 130 |
|
%p = the number of connected components |
| 131 |

Hopefully you mean McCabe's cyclomatic complexity\\ |
| 133 |
|
% e = no of arcs | n = no of nodes |

|
e-n+2 | 18 - 14 + 2 = 18 - 16 = 2 \\ %men vad säger nu detta |
| 135 |
|
This tells us the number of tests we have to do to cover |
| 136 |
|
each path in the program. It could also be used to give a |
| 137 |
|
estimation of how complex the final software will be. If |
| 138 |
|
higher then 20 it should be seen as a high risk project, |
| 139 |
|
and if higher then 50 as a very high risk project. %nuffrorna kommer från http://www.sei.cmu.edu/str/descriptions/cyclomatic.html |

svar |
The internal attributes can be measured from within the |

| 186 |

attributes and metrics. Present the assumptions that you will use |
|
| 191 |
while creating of the quality model. Provide an explanatory text |
This is partly since the internal attributes can be |
| 192 |
|
measured more ``directly'' then the external. For |
| 193 |
|
instance loc is easy to count while usability is a lot |
| 194 |
|
harder to measure. For the internal attributes one can |
| 195 |
|
expect to be able to get absolute values while on the |
| 196 |
|
external attributes one can expect them to be less |
| 197 |
|
accurate. |
| 198 |
|
|
| 199 |
|
However several of the internal attributes (if not all) |
| 200 |
|
does affect the external attributes in a way that can |
| 201 |
|
(in most cases) be predicted. One can for instance say |
| 202 |
|
that in a specific solution if the loc is increased |
| 203 |
|
(both with comments) then one could expect to get a |
| 204 |
|
higher maintainability. Also most of the external |
| 205 |
|
attributes can be affected via the internal if the |
| 206 |
|
developers keep the external attributes in mind. |
| 207 |
|
|
| 208 |
|
In most cases (if not always) the customer of the product |
| 209 |
|
is more interested in the external attributes. Does this |
| 210 |
|
mean that the external attributes are of ``greater'' |
| 211 |
|
value to the team developing the product? |
| 212 |
|
|
| 213 |
|
Not always but in many cases. Also one should keep in |
| 214 |
|
mind that just because the external attributes are more |
| 215 |
|
important that the internal could be forgotten. |
