Recently, I did some research into the state of project management software (including SaaS) for a Key Stakeholders Blog article.
Many mainstream products, including OmniPlan, follow the Microsoft paradigm: Bottom up planning using a task list/Gantt chart. However, best practice is to start with a scope management tool like a WBS.
Here's the best practices work flow: WBS > PERT (Network) > Gantt
Why does OmniPlan follow the MS Project paradigm that is not best practice? There are effective WBS and PERT chart tools for the MS Windows platform. Unfortunately, I haven't been able to find a functional counterpart for Macs.
Has the OmniPlan team thought about breaking away from MS, and just doing what's right?
By the way, I believe OmniPlan is a terrific product. It has huge potential.
Here's a link to the article with the complete rundown:
