SDC, Part 2: Release and iteration planning

This blog is an introduction to creating projects, versions and releases using PureCM 2010.

Creating a Project


The first thing you need to do is create a PureCM project. A project is a self-contained set of files. You can share files between projects using components, but this is too big a topic to discuss here.

Launch the PureCM GUI and go to the Projects View. Right-click the ‘Projects’ tree item and select ‘New Project’. Here you can specify a name and description for your project

Creating Versions


A project will contain one or more versions. How many versions you create and what you call them will depend on how you develop your project.

The first question you need to ask is: Do I need to develop different versions of the project at the same time? If the answer is no then you only need a single version – probably called something like ‘Development’ or ‘Main’. If the answer is yes then you need to create a PureCM version for each version you will be working on.

For example, suppose the project is a website which is constantly being updated and the latest files are uploaded to the web server at various points. The project needs to only have one version.

Or suppose the project is an application which is released as incremental versions, but each version contains the latest code. The project needs to only have one version. You could create a PureCM version for each version of the application – but it is more work for you.



Now suppose the project is an application which is released as incremental versions, but each version does not contain the latest code. So for example you release ‘Release 1.1’ and start developing ‘Version 2’. You then find a bug in ‘Version 1’ so you want to release ‘Release 1.2’. But you do not want ‘Release 1.2’ to contain the ‘Version 2’ features (Features 2 & 3). The project needs to have a version for ‘Version 1’ and a version for ‘Version 2’.




To create the first version right-click the project and select ‘New Version’. Here you specify a name for the version. The initial version will always be created from scratch. To create a version from another version right-click the first version and select ‘Create Version From’. You will notice that now the new version is based on the version you selected.

It is very important that any new versions are created from the correct version, e.g. ‘Version 2’ is created from ‘Version 1’. This is so that ‘Version 2’ will initially contain the same files as ‘Version 1’.

Staging or Promotion Models


Another reason to create versions is to support staging. The most common example of this is where you have a ‘Development Environment’ where your developers submit code and an ‘Integration Environment’ where your testers test the code. What you want to avoid is having a code freeze – stopping your developers from submitting changes until the testers have tested the code.

To achieve this simply create the ‘Development’ version as described above. From this you can create the ‘Integration’ version. All the developers will work on the ‘Development’ version and at various points a manager can merge the changes into the ‘Integration’ version.




To support staging and parallel development you need to create the staging version from each development version. So you will initially create the ‘Version 1 Development’ version and from this you will create the ‘Version 1 Integration’ version. When you are ready to start developing Version 2 you will create the ‘Version 2 Development’ version from the ‘Version 1 Development’ version. You will then create the ‘Version 2 Integration’ version from the ‘Version 2 Development’ version.




Of course you are not restricted to one staging environment. For example, you might create the ‘Production’ version based on the ‘Integration’ version.

Iterations or Sprints


A common question is how to handle iterations or sprints and whether you should create versions for them. The same rules apply here as with parallel development. If you are working on 2 or more iterations/sprints in parallel then they should be separate versions. If the development is linear then you only need one version.

Creating a Release


A release is a snapshot of the version at the time the release was created. By default, the files within the release will not change. So a release is used by the build managers to build the release and by the developers to test for a bug within the release code.

To create a release, right-click the version you want to create a release from and select ‘New Release’.

To view the releases of a version, right-click the version and select ‘Show Submitted Tasks and Releases’. This will give you a list of the changes submitted against this version and where the releases were created.






In this blog you have learnt:

  • How to create a project.
  • If you work in parallel development then you need to create a PureCM version for each new version of the project.
  • If you work with staging environments then you need to create a PureCM version for each stage.
  • When creating a version it is very important to create it from the correct version.
  • How to create a release and view all the releases for a version.

The next blog ‘SDC Part 3: Defining a Work Item’ will describe how to create tasks and features within a version and assign them to a developer.
