OpenText Dimensions CM vs. OpenText Service Manager

Serena CM is well suited to highly controlled, audited, and process driven environments. It will allow strict segregation of duties, and change traceability. If implemented correctly it will help you quickly build trusts with your auditors. It is also well suited to environments that require constant branching and merging. Due to the complexity of the product and learning curve for your development and operations team it may be overkill in a small shop with loose rules

HP Service Manager (HPSM) is well suited for a big company and it does the job that it's intended to do but it's not perfect. It has a fairly large learning curve for searching Knowledge Management (KMs) and it takes time to learn how to be fast at creating/resolving tickets while on calls. I have been using HPSM for about 2 years now and we recently moved from the desk client to the web client and we are seeing a lot more issues than we did with the desk client. They keep coming out with updates for it so eventually most of our issues will hopefully be resolved. Overall the web experience is better as it looks more modern than what we used in the past.

• Code Promotion: Dimensions CM allows supervisors to control changes to code, in that they delegate requests to developers, and act as a gatekeeper prior to promoting to the next environment. This functionality is configurable so you can set up a workflow that best fits the structure and requirements of your own company.
• Code Repository for changes and versioning: Code can be checked out by item or by synchronizing folders. Code revisions can be compared against other revisions or work files. Item histories show which developers made which modifications, and which supervisor and operations personnel were involved in assigning the request and promoting the code to each environment. Additionally a pedigree will show a stream diagram which graphically displays branches and merges.
• Deployment: Serena Change Management offers help automating deployment including integrations with SVN and Jenkins. Its newer versions also have a powerful graphical deployment automation tool (Serena Deployment Automation- SDA). It comes with a certain amount of licenses built-in. If you have a many nodes to deploy to there will be separate licensing costs for that.

• The only major negative that I have encountered with Serena CM product is that the very power and flexibility of the tool means there is a risk that you will make a mess of things. In other words it gives you plenty of rope to tangle yourself with. I recommend careful, well thought out deployments implementing the built in roles and workflows that can be turned on and configured, using a consistent methodology.
• My experience with the Serena help desk support has not been impressive. Though reasonably polite and diligent, the technicians were well trained, and often gave bad advise and terrible scripts. On several occasions I had to rewrite scripts they have me; if I had run them as provided they would have caused even more difficulties than the problem I was trying to solve. I speak of the support in the past tense because I conditioned myself not to call them, it was usually just easier to solve nay problems my self. They do have a good account management team though, and for any major issues you can go thru them.

• When you search Knowledge Articles, it is not like Google, and you need to learn how to search for what you need.
• It takes a very long time to close tickets in HPSM. Here are the steps to close a ticket. 1. Add notes. 2. Add KM 3. Click Resolve 4.Click Save 5.Click Close 6.Click Okay to Message (ticket has recently been modified) 7. Click Close.
• It's slow and sometimes crashes/freezes and you lose all the information you may have entered. I usually use notepad++ to gather all my notes and paste them into HPSM.
• When searching previous tickets the preview pane does not allow for sorting by date to have the most recent at the very top every time you pull up previous tickets. Sometimes there are pages and pages of previous tickets and you have to click and scroll to get what you need.
• I click on search KMs and it takes me to a blank page and I have to click the back button which then brings me to the search KM page.

Serena CM is superior to Microsoft Team Foundation Server (TFS) in overall functionality, but does not have very good native integration with Microsoft. Therefore in a Microsoft centric shop with no audit needs ,TFS would be better. Otherwise I would choose Serena CM
