Viva goals is just an intuitive way to track Objectives, key results and the project progress that's feeds into them. It's easy to setup and get going and there are a number of integrations that make the actually tracking very hands off, depending on the data source. We are very heavy into MS products and it integrates tightly with a variety of MS and non MS data sources. Review collected by and hosted on G2.com.
Just getting people in general to understand the OKR thinking. I wish the training for it was integrated into the platform to make it easy to learn. Rather than having to go to the MS support site to watch a training video. Review collected by and hosted on G2.com.
