Branching and Merging–Proceed with Caution!

clock February 25, 2011 08:59 by author Chad Albrecht

Over the last few years I have worked with teams that feel a need to using Branching as part of their “best practices” tool set. The ALM Rangers were even nice enough to show teams how to build a mature branching scenario in their Visual Studio Team Foundation Server Branching Guide 2010.  PROCEED WITH CAUTION!  There is a large overhead in using branching and merging.  The branching part is easy, it’s the merging part that will kill you.  Done infrequently, the merge process can be a huge undertaking in many cases taking days to complete.  Here is a quote from the original VS 2005 Branching and Merging Primer:

A branching and merging strategy involves a tradeoff between risk and productivity. You trade the safety of working in isolation for the increased productivity of working with other people. The productivity increases come with a cost—the additional effort required for merging software assets sometime in the future.

Often, there is no need to adopt branching as the teams are small enough or using shelves will suffice.  If you feel you need to branch, do so for the right reasons.  What are the “right reasons?”  In a nutshell, you absolutely NEED to isolate some code from other teams/repositories.  Examples might include:

  • Development on a new feature is continuing while the current version is releasing.  (branch by feature)
  • Teams are practicing design by contract and only want the final contract to be used by other teams. (branch by team)

What are some branching and merging anti-patterns to watch for? Here are few (thanks Chris Birmele):

  • Merge Paranoia—avoiding merging at all cost, usually because of a fear of the consequences.
  • Merge Mania—spending too much time merging software assets instead of developing them.
  • Big Bang Merge—deferring branch merging to the end of the development effort and attempting to merge all branches simultaneously.
  • Never-Ending Merge—continuous merging activity because there is always more to merge.
  • Wrong-Way Merge—merging a software asset version with an earlier version.
  • Branch Mania—creating many branches for no apparent reason.
  • Cascading Branches—branching but never merging back to the main line.
  • Mysterious Branches—branching for no apparent reason.
  • Temporary Branches—branching for changing reasons, so the branch becomes a permanent temporary workspace.
  • Volatile Branches—branching with unstable software assets shared by other branches or merged into another branch.
    Note   Branches are volatile most of the time while they exist as independent branches. That is the point of having them. The difference is that you should not share or merge branches while they are in an unstable state.
  • Development Freeze—stopping all development activities while branching, merging, and building new base lines.
  • Berlin Wall—using branches to divide the development team members, instead of dividing the work they are performing.

Remember, think long and hard about jumping into branching and merging.

User Story Role in TFS

clock March 11, 2010 08:47 by author Chad Albrecht

As I mentioned, I received numerous questions during my presentation at the WI .NET User Group a few weeks back.  One of the them was: “Is there a way to add the subject of a user story as an explicit field?”  After probing the individual a bit, I discovered he wanted to be able to sort user stories bases on this field.  As a recap a user story is typically in the form:

As a <type of user> I want <some goal> so that <some reason>

In this post I will show you how to add the <type of user> or user story role to the user story in TFS 2010.

First make sure you have TFS Power Tools installed.  For the TFS 2010 RC, download them here.

Second, I’m going to show you how to do it using the MSF for Agile v5.0 User Story Work Item Type (WIT).  While other templates are going to be slightly different, you can use this same method as a general guideline on how to do this.

 

Step 1:

Open the “User Story” WIT from the Server.

Step 2:

On the Fields tab click New.

image

Step 3:

Setup the new field similar to that below.  You will probably want to change “MyCompany” in the Reference name to be the name of your company.

image

Step 4:

Still in the Field Definition dialog, click on the Rules tab.

image

Step 5:

Click New, select ALLOWEDVALUES and click OK.

image

Step 6:

In the ALLOWEDVALUES dialog continue to click new and enter the desired roles until you have all the roles you want to use.

image

Step 7:

Click OK back to the WIT editor.

Step 8:

Go to the Layout Tab.

image

Step 9:

Right click on the Column node under Group – Classification and select New Control.

image

Step 10:

Setup the fields similar to the following:

image

Step 11:

Click Save.

 

Your’re Done!

Your User Story screen should now resemble the following:

You will also be able to add the Story Role column to queries and sort and filter by it.

Good luck and enjoy!



Succeeding With Agile & TFS 2010

clock February 23, 2010 04:17 by author Chad Albrecht

Making the transition to Agile can be challenging for even the most seasoned organization. Having good leadership and the right tools can make all the difference. Drawing on nearly two decades of experience Chad will be walking us through methods that can be used to avoid common pitfalls and using Team Foundation Server (TFS) 2010 as an Agile platform. In this highly interactive session, Chad will demonstrate some of the new features of TFS 2010 as they relate to Agile estimation, planning, execution and measurement. If your organization is considering a migration to Agile or the TFS 2010 platform, you are encouraged to attend.

 

I presenting the above topic tonight at the Wisconsin .NET User Group.  Register Here!

I will also be giving the same presentation at the Madison .NET User Group on March 3rd.  Register Here!

Look for a presentation in the Chicago Land area towards the end of March.
