Costs of Building/Maintaining Home Grown Tools vs. Third Party Tools

Costs of Building/Maintaining Home Grown Tools vs. Third Party Tools

Post by Guy Mart » Thu, 30 Mar 1995 12:48:07



I am currently part of a committee at my company that is putting together the
proposal for our next generation of SCM tool.  However, I need some help from all you
net-folks out there regarding "home grown" vs. third party tools.

There is a camp within my company that is lobbying hard to keep the home grown tools and
all the associated support and development costs associated with them.

Does anyone out there have some hard numbers on how much (man/hours, dollars) it really
takes to support home grown tools, as opposed to third party tools?  FYI, my company is
involved in Systems Integration and custom development of software, and has roughly
700 people, and we would especially like to hear from companies with similar demographics.

If you could send me this information, I would be eternally grateful.  I will summarize
to this group if there is enough interest.  Thanks a lot.

I would definitely like this information.  We as well are investigating
homegrown tools as a replacement for third party solutions.

Well, in a nutshell: At the last company I worked at, I had the
pleasure(?) of using two separate home grown systems. Some observations:
1. Ask yourself the question: Is building and maintaining CM tools part
of my core business? If the answer is "no", then you probably won't want
to expend the effort of 2-8 people it takes to keep it working correctly.
2. Can you say "text-based interface"? Unless you have some GUI wizards,
don't expect a very friendly interface.
3. Is your CM process clear? If not then you tool will have to be *real*
flexible. Flexible systems are not known for efficiency.

I guess you realize by now that I think both systems sucked. One never did
work correctly (just imagine the king of the CM fiefdoms reaction when he was
told that his groups magic tool lost several days of changes one time (50
developers). The interfaces were less than friendly. Makes didn't always
work. Ick. :( A tool is going to run about $6K + 15% maint/year. How much
will it cost to develop and maintain a custom product??????

Guy,

Rob Lesieur made some good points that are worth bring up for your
company, although I think his support numbers are low.  If you are not
marketing CM products, don't get into developing them. Commercial
companies have development teams of 50 or more developers (send me pvt
email and I'll name the co I know for sure).

Another thing to keep in mind is the underlying changes in technology
that are appearing (re Rob's comment of can you say text based interface..
 ;-). Application of GUI and object oriented databases and technologies.
Use of knowledge based approachs to build in more intelligence to your CM
database. Even if your company is using these technologies would they be
willing to apply there best people to an internal (can you say overhead...
) development with no hard $ return?

I am working on a very large project, >100 developers at my site alone.
At my site we have multiple CM databases. We are using a commercial tool,
which one is not important. Local DBA and tool support is provided by ONE
person. Once set up the tool is used by the development team as part of
its development process and requires minimal support. Oh that person also
acts as the lead support person for our project which involves many 100's
of developers accross many companies. You have got to get your management
to ask themselves if therre internal system could do the same.
