Bearbeiten von „Request for Change“

==Why this?==
Customers ask for features regularly. In the longer past some things were installed where they were needed. Then we changed to a policy wich aimed to keep all the servers set up the same way. Denial of requests happened more often. But the side effect was, that the same questions were investigated and decided multiple times, as we lost track of the requests. So we will protocol them here from now on.

With the information gathered we can now see
* what clients want
* popularity of a request
* why the clients need it
* which information was available at the time of the decision
* why the decision was taken like this
* if reconsidering is needed


==Apache==
===PUT method===
# '''Link:''' [http://www.w3.org/Amaya/User/Put.html Configuring your WWW server with the PUT method]
# '''Decision:''' 
#* '''Result:''' will not be installed
#* '''By:''' hja
#* '''When:''' 07.2014
#* '''Reason:''' we have no security layer for PUT as we have for GET and POST, so it would be a major change
# '''Workaround:''' FTP protocol offers the same methods. Programmers should use this protocol instead.

==How it works==

===A new request===
You have an incoming request that needs to be judged, copy both parts of the [[Request_for_Change#Entry_Template|template source]]. Fill in the '''headline(s)''' and the '''link''' in the first part of the template. If the scope (i.e. "PHP") is already listet, skip it. Then fill a table row with '''date''', '''reason''' and '''contact address''' of the client.

Now inform the one that should decide about this entry.

===First decision===
The decision taker will fill in the decision part of the entry and inform you that it's done.

===Workaround===
Find a '''workaround''' if possible and not given yet by the decision taker and leave it there. 

===Client information===
Time to tell the client what the decision is and why it was taken like this. If you get feedback, add it to the table row of your client.

===It is asked again===
''(So it must have been denied or postponed until now.)'' 

Add an additional line to the table like before with your clients reasons to have it. Inform your client about what was decided in the past. And note his feedback as soon as it arrives.

===Escalate it again===
You may escalate the request again, if you feel that:
* your new reason has changed the importance of the request (i.e. postfinance requires it to continue my payment processing module!)
* there are more than 5 times the same reason given in a short period of time (ie. 1 request/month)
* the reasons of denial or postponing are not valid anymore

==Entry Template==
