Perdoo seems to be a good fit for us. We're about 60 employees, we'll see how well it scales with us but I don't see why it wouldn't. Perdoo is a good tool especially for orgs that haven't done OKRs or goal setting, and need solid structure and support (like the webinar) to get people engaged. A tool only works if people use it!
Workboard is well suited in any organization IMO, it allows the individual business units to quickly set, define, organize and track their respective OKR's and align them with the larger business goals. The speed at which we're able to do this with Workboard has allowed us to spend more time on the goals themselves and less time on the management of the goal-setting exercise.
OKR roadmap: I like how clearly this lays out the connections between the different levels of OKRs (team, company, long term etc)
OKR Webinar: they have a great OKR 101 type webinar that we made all our leaders go through, even those who had worked with OKRs before, to ensure that we were all on the same page. Perdoo is very intentional and thoughtful about the terms they use.
Initiatives: I really like that Perdoo goes down to the initial level, not just OKR. Initiatives are the projects/tasks that roll up under each KR to actually get to the result.
slack updates: I like seeing the notifications come through when colleagues update something in Perdoo. fun to see progress!
Project management at higher level - includes tasks assignment, visual representations of the project status and deadlines
Increases the team members' sense of ownership - especially for people that are not used with or exposed to dedicated project management tools like Microsoft Project is.
User collaboration - which in turn reduces the communication via email
Increases the efficiency of the meetings - by quickly going through the action items and updating the task progress in the tool itself
Perdoo was much more focused on the core OKR process than Weekdone, and our users vastly preferred it during trial tests. Google Sheets is flexible enough to support almost any workflow, which is its biggest strength, but also its biggest weakness - we wanted a tool that is a bit more rigid in enforcing a particular process.
Workboard vs Microsoft Project(and its Server) is like comparing a regular sport car with Formula 1 cars. One is lighter, nicer, with a broader audience, it gets you there fast while the other one is dedicated, not as nice, especially built for it, not for everyone and it will get you there much faster.
