When I first started using CRM I made plenty of mistakes that cause me to physically cringe when I reflect on them, so I hope that by sharing some tips that I’ve picked up on my journey, I may be able to help others avoid them.
I’ve been discussing customisation best practices internally in my organisation and, since I’ve been documenting them anyway, I thought it would be worth sharing my thoughts.
This is probably my number one tip. If you’re doing any sort of system customisation, please put it in a solution container; NEVER make changes directly to the base solution – just pretend the “Customize the System” button doesnt exist.
By using a Solution you can avoid the dreaded new_ prefix on newly created fields/entities/web resources, etc. and use your own publisher prefix. A solution also operates as a container for all the customisations you are making to the system, which makes it significantly easier to understand what changes have been implemented for you and anyone else who may be working on your system.
One of the biggest debates on the use of Solutions is whether you should Managed or Unmanaged. I have used both in different systems and I don’t think there is a single right answer; it all depends what is right for you in your system (though Microsoft officially recommend the use of Managed Solutions (see https://msdn.microsoft.com/en-gb/library/gg334576.aspx#BKMK_UnmanagedandManagedSolutions)
There are plenty of posts by more experienced heads than I discussing the differences between the two solution types, and weighing up the pros and cons of each, so I’d recommend seeking them out for further reading.
The only real piece of advice I’d like to add is that Unmanaged Solutions are easier to manage (pun intended), and you can always convert an Unmanaged Solution to a Managed Solution in future if needs be; just be aware of the potential for unintended changes to be added to the solution by over-zealous developers during UAT or while it is live in the Production environment, leading to solution disparity. You should weigh up the control of Managed Solutions versus the flexibility of Unmanaged Solutions in any decision-making.
Aligned with the use of Solutions is to ensure you have a rigorous and consistent approach to versioning. Using version numbers makes it a lot easier to manage your solutions, and to identify issues if and when they arise.
My approach is to use the standard of Major.Minor.Release (#.##.####), as defined below:
Major – this should be incremented every time you introduce some significant functionality, change the phase of the project, or if you upgrade to a new version of CRM
Minor – this should be incremented every time you release an update to the solution that introduces minor features or changes that are building on existing functionality.
Build – this should be incremented with every single release, and should cover bug fixes, etc.
There are lots of different version numbering schemes available (e.g. Major.CRMRelease.Minor.Release, Year.Month.Day.Revision, etc.), and it doesn’t really matter which one you use – the important thing is that you use a consistent version numbering scheme in your development, and that everyone working on your system understands the numbering scheme. I’ve previously inherited a system developed by a Microsoft Partner who had used 4 different numbering schemes when deploying solutions which gave me no end of headaches.
I’m sure I’m not alone in not particularly enjoying writing documentation, but also cursing out any other developers who dare to release a solution without documentation. As important as it is to develop system updates, writing appropriate documentation is equally important. I’m not suggesting that you include War & Peace with your releases, but adding a few notes on the release history to the solution description field will go a long way to helping both future you, and anyone else who may be working on your system
Having these little notes provides a perfect aide-mémoire when you come back to work on the solution in six months time, and taking the two minutes to do it now will save you hours down the line. I like to keep a more detailed release note history to go with my solutions too; for a great example of detailed release notes you could look at ClickDimensions.
My next post will outline my tips related to new entities, fields, views, etc.
