Lucidchart

Abundance of features, which makes this software so versatile. You can basically use it for every task and project.
I mainly use it for mind-mapping and brainstorming, but it's also equally useful for taking notes, story-boarding, gathering ideas, presenting, drawing graphs, schemes and organisational charts, Gantt timelines, or even team building (it works great as an online whiteboard).
What I really love is ease of use and multitude of features. Every time I wish I could do something, it turns out it's possible. Seems like developers really thought about everything and listen closely to their users and use cases.
Also, you don't really feel that the software is locking you in--you can export your projects to similar software/platforms, e.g. Visio.

Getting to know some features takes time and energy, documentation and tool tips have some space for improvement.
Also, licencing model could be more friendly for small companies or people who use it as backup/auxiliary software only (en entry level paid subscription model).

1) Super easy to get started with simple registration options.
2) Very flexible sharing and collaboration options.
3) Multi-edit a document in real time with other users.
4) Easily lock down access to documents.
5) Many predefined industry standard documents to start from
6) Large list of export diagram export options. Examples, PDF, PNG...

1) At times the shape locator tool on the left hand side can be confusing depending on the document type you are working on, for example if you are working on a DFD diagram, the shapes directly related to the diagram should always be visible first after which other shape groups should be searchable.

Very intuitive and easy to use business process mapping software that can be used through the browser. I was looking for a MS visio replacement to run workshops with and this met my needs. I like the pre-built templates and the fact that i can have my colleague update the same business process map at the same time im using it (only available if you upgrade). The ability to publish to a MS visio format and a weblink is also useful. You can access the software directly on your browser as a SAS so it doesnt require any installation of software which makes it convenient if you're jumping between computers (it allows you to access your diagrams anywhere since its stored on the cloud)

-There's some minor glitches when mapping out business process lanes and performing some of the tasks. Formatting the process maps can be annoying sometimes and it does not have all the formatting customizability that a more robust business process mapping tool like MS visio has. Sometimes the browser is not responsive if you go idle for too long.
-I don't like the fact that users need to register/create an account if I want to share the published link with my business process maps to them
-Costs are kind of a turnoff because I'd rather pay a one time fee rather than a subscription cost since its not every day you'll be using this software
