%huh? - jag kollar på denna... men vill du ha den så;) |
Assumptions: We are using an iterative development |

max 8 sidor (totalt; inte på denna;) |
process, we are using function points to measure progress, |
234 |
|
we are using a good configuration management tool, we are |
235 |
|
identifying risks before starting a project, we are, but |
236 |
|
not always using uml for our projects. |
237 |
|
|
238 |
|
Since we are working on web-based applications we also |
239 |
|
assumed that we are selling those to a customer. This made |
240 |
|
us make a value based quality view. This made us decide |
241 |
|
that usability, lernability, reusability, maintainability, reliability, |
242 |
|
is the most important external attributes. The internal |
243 |
|
attributes are not considered as important, other than to |
244 |
|
help up the external. Customer satisfaction does supersede |
245 |
|
this thou. The external attributes has the following |
246 |

impact on customer satisfaction: \\ |

Usability & High & |
251 |
|
Decides if the customer fells that he may use\\ |

253 |

|
Learnability & High & |
257 |
|
The quicker the end-user can learn to use the \\ |
258 |
|
& & program, the quicker he feels the value of the\\ |
259 |
|

260 |

261 |

Reusability & Medium & |
262 |
|
This is only important if using agreements like\\ |
263 |

& & ``avtal 90'' or similar that gives us the freedom\\ |
264 |

267 |

268 |

Maintainability & Medium & |
269 |

This is only important if we are using the \\ |

reusability from above. And only to support that\\ |

274 |

Reliability & High & |
