1. Workflows can be REAL TIME (Synchronous) or ALMOST REAL TIME (asynchronous) and if you are a business user creating workflows you want to coordinate the timing. In the world of plugins and extensions timing coordination of steps is all part of the job, but in the world of workflows sometimes it is easy to forget about what we are really asking for.
2. Deleting and Cleanup in the world of customization and multiple environments are a specialized thought process. The system supports a merge mindset so when you want to do cleanup (and you are using unmanaged solutions) you want to make sure you cleanup all your environments. I like to use the technique of naming fields, business rules, forms, views and other such configurations in DEV with a prefix of something like ZToBeDeleted so that after a deployment to TEST and PRODUCTION it is easy to do house cleaning.
3. You are not the only one extending and configuring. Coordination equals huge successes and incredible power and depth. It is a product that is always evolving from the power and insight of the incredible team at Microsoft and then there are the other new features that are purchased, reviewed, updated, coordinated and released. If you are writing unsupported code you are asking for headaches OR if your hired gun is writing unsupported code. Take the time to get it done right. Take the time to vet your resources. A low hourly rate does not mean long term reduction in cost.
4. Software as a Service (SaaS) in the world of Dynamics CRM means that you are continuously getting the chance to improve your businesses cutting edge differentiator through the use of the newest technology and business techniques. Get the Learning Mindset and embrace the wave while also taking bite sized, very manageable growth steps forward. Setup your environment so you have a DEV, TEST and PRODUCTION instance so that you can have DEV upgraded first, then TEST (with a release to TEST and Regression Testing) and then roll to production. For smaller firms perhaps only two instances, but always give yourself that learning arena for the larger feature releases.
5. Just because it looks pretty, and has a really cheap initial price does not mean that you won't be paying more in the long run. In the world of ONLINE and the CLOUD do your research with other customers. Understand the 1, 2 and 3 year average costs and understand what you get for the money. The models can be very different. There are hundreds of applications that can be replaced by Dynamics CRM and with the right resources (trained helps) the price is right. Just because Access and Excel are available with office, doesn't mean they are the right solution for a multi-user environment where people need to share real time data across many different devices. Oh and then there is the Out of the Box integration to the Office 365, SharePoint, Microsoft Excel E-Mail, and so much more.
It really is mind blowing.....
