Hi David,
Thanks for your thoughts!
I agree with your points. To an extent, management don't really care how
we implement SCM - as long as it's effective and secure they will trust
the "tech-wranglers" to do the right thing and not impede upon the
company's workflow. Fortunately the industry in which I work is VFX, so
"cutting edge" software is at the core of what we do. I am not imposing
Git because of my own personal preference, I honestly believe that SVN
is simply not the right tool for the job - which will increasingly
involve multi-site collaboration that spans departments as well as
timezones. The ability for two disparate teams of developers to
collaborate effectively without polluting the global codebase is essential.
The limitations with SVN are becoming more and more apparent -
especially now that we have now embarked upon a fairly radical shake-up
of our existing software stack.
I have explained all this with senior management, some who have heard of
Git (and its reputation) and they pretty much say "about time too".
The hard part is that we have two tiers of developers - core software
techies (C++, python) and scripters (python, MEL - these are the people
who make VFX movies, for example, happen). The former will have no
problem with Git, the latter probably just don't care - they just want
to check stuff in and out.)
What I need to do is create this hybrid system that enables the
scripters to pretty much carry on as usual, and to provide the necessary
tools to do SCM more effectively - ie without the overhead of a brittle
SVN environment. If all goes well, we'll take the plunge and make the
switch permanent.
Yes, the technical sell for Git is the easy part, the cultural sell will
be harder. It's up to me to make the business case to the bean-counters
and make the technical transition painless. So far, so good.
I've posted this before, the scripts I am using are available at -

The more eyes on this the better...
Cheers

Hi William,
I have been following this thread with interest so I thought that I
would just throw in my thoughts!
While maintaining synchronization with Git is part of what is needed I
suspect that this will not entirely convince the management of your
company that Git is the way forward.
They probably see Svn as a safe repository ... The company's assets
(intellectual property) are on a central server that is backed up, and
the contents of that repository can be audited and so on. They may be
thinking about things like SOX compliance too.
So if you want them to accept Git as a replacement for svn then you
need to understand and address these concerns. This means that you
will have to have a conversation with them. To a large extent this a
people thing ... technical solutions won't necessary convince them.
They are running a company based on the knowledge and information they
own - and they want to make sure that it doesn't get lost, stolen,
corrupted, or whatever. And they are accountable to the shareholders
for this.
Also, you say that they have been using Svn for donkey's years, so
from a corporate perspective it probably does what they want and need.
Otherwise THEY would have decided to change it.
I am in a similar situation and while developers clearly want to use
gIt, the motivation from a corporate perspective is less clear and can
be perceived as introducing risk. So we are looking at the wya in
which repositories are set up, the topology of git repository
networks, use of Gitosis. Gitolite and Gitorious, and so on, to
provide some security in the corporate environment.
Every company will have a different view of this so there is no
'right' answer. A lot depends on the type of product you produce and
how long it will need to be supported. If you have products that need
to be supported for 10 years or more then promoting a tool that is 5
years old may also raise some eyebrows! You need to have the answers
ready :-)
Get it right and you will be seen as a hero who understands the
business. Get it wrong and you will consigned to the religious nerd
category who just wants to promote his favourite tool ... which I
would hope is not the case :-)
Good luck with this ... you are not alone!
