Daniel from Kansas City here.
I work as a PM in a lead generation company. One of the projects I've been working on for the past 6 months is implementing Jira and Confluence across all departments and companies. It's been a real challenge in the implementation, mostly through the need to highlight the current processes and drive them to the next level.
Only few months after rolling everything successfully - everyone was able to see the benefits this brought (easiness to communicate and track, eased reporting, transparency, improved productivity and a huge increase in visibility).
We are using Jira now to literally organize the full day-to-day (supported with well outlined documentation in Confluence), from tasks - requests - managing objectives and employee goals.
The amount of customizations to the exisiting jira workflows we did is huge (followed with many add-ons and many more to come).
So if you are in charge of organization/operations or wondering how you can utilize those platforms to take your company to the next level, do not hesitate to give me a shout. I am happy to share our story and what and how we've done it.
