Azure DevOps Server (formerly Team Foundation Server, or TFS) is the on-premise version of Azure DevOps. To license Azure DevOps Server an Azure DevOps license and a Windows operating system license (e.g. Windows Server) for each machine running Azure DevOps Server.
Azure DevOps is good to use if you are all-in on the Microsoft Azure stack. It's fully integrated across Azure so it is a point-and-click for most of what you will need to achieve. If you are new to Azure make sure you get some outside experience to help you otherwise it is very easy to overcomplicate things and go down the wrong track, or for you to manually create things that come out of the box.
Omnigraffle is great for documentation, mapping, flowcharting, and other technical diagramming scenarios. It's simple enough to bang out a quick illustration and powerful enough to build complex blueprints for complicated technical systems. If you need cross-platform compatibility, though, you're probably better off looking elsewhere. If you want complex integration with data sources (ala Visio's SQL Server integration for shape metadata), OmniGraffle also falls short — but those scenarios are few and far between in my experience.
OmniGraffle is fairly simple to use, but the one thing I think it does best is working with curved lines, particularly if you are using some of the available arc templates. Drop an arc onto your page, then tell it the dimensions it needs to be, and viola! Done. Manipulating the arcs is as simple as clicking and dragging offset points.
OmniGraffle has also done an excellent job in stirring up the creative minds of many people who create templates and tools to work with OmniGraffle (not that Microsoft hasn't done so either), and managed to get the bulk of those into well organized repositories.
What it all boils down to for me is: it just works. One doesn't need to have a computer science degree to work with it either. It is as simple or complex as you want it to be.
I'd love to be able to keep more than one of the different tool tabs open at a time.
The stencils are amazing. Would be great if a whole lot more of the free ones came standard as opposed to having to download them from Graffletopia or other sites.
Because we are a Microsoft Gold Partner we utilize most of their software and we have so much invested in Team Foundation Server now it would take a catastrophic amount of time and resources to switch to a different product.
For standard users the interface is friendly. but if you are a manager some tools are a little confusing to use, like the query system that you always need to create from scratch. Templates should be more helpful for queries and for standard procedures that you need to duplicate PBIs over time. The search history of Work Items is a little painful to use.
I have not had to use the support for Azure DevOps Server. There have never been any issues where I was not able to figure it out or quickly resolve. Our Scrum Master has used support before though, and the service has always been prompt and clear with a customer-focus
In my opinion, DevOps covers the development process end to end way better than Jira or GitHub. Both competitors are nice in their specific fields but DevOps provides a more comprehensive package in my opinion. It is still crazy to see that the whole suite can be used for free. The productivity increase we realized with DevOps is worth real money!
While these other tools are great for what they are, OmniGraffle’s solid focus on and support for diagramming makes it our tool of choice for communicating workflows and concept relationships, creating documentation, and creating other diagrams. Its libraries allow us to create designs quickly, and its ease of use enables us to use the tool widely across the company without much time or effort spent on onboarding.
It has streamlined the pipeline and project management for our agile effort.
It has helped our agile team get organized since that is a new methodology being leveraged within the Enterprise.
The calendar has improved visibility into different OOOs across the project team since we all come from different departments across the larger organization.
Omnigraffle isn't an expensive software tool, so there isn't really any negative from the perspective of raw cost. Thinking in terms of time spent using it on a project - what you create in omnigraffle will inevitably lead to a dead end. It's useful only as documentation. There are other tools like Sketch that integrate into prototyping software and can create useable visual assets for applications in addition to being able to create wireframes.
