What a shift in the Microsoft BI stack. You can’t show the BI Burger to your clients anymore. Maybe there was not enough demad for the planning peice for Microsoft to justify continuing the development and sales effort around the product. Now we have yet another example of an acquisition that soon was re-worked and then kill by the acquirer.
I have also heard rumors that Gemini might be something to take the place of the planning piece. You’d need some sort of workflow engine, but maybe it could work. We’ll see.
Also, the layoffs affected the sales area in BI significantly so MS is definitely cutting their loss in BI. I agree with Chris that it is important for Microsoft to publish some sort of new roadmap. It makes it hard for partners to invest in new Microsoft products if they kill them off so soon after launch.
