The company that I work for uses this and we are a non-digital product company. We have been implementing it for nearly a year now and it seems to be going well. I act as a “subject matter expert” but soon I will be scrumming daily with the teams. Depending on the projects and company sizes you need to have an employee just to help run the teams (scrum master) which also acts as a team member filling in when they can, ours is in an engineer by trade. I haven’t fully developed my opinion of it yet, so more to come. I have visited alot of workspaces though recently that implemented scrum or a variation of it, and all of these companies were manufacturing or non-digital product companies. Its definetly made for software companies but there are alot of non software companies trying it out, im not sure if its just a trend that will fade or remain, we shall see.
