The primary job of the ScrumMaster is to remove impediments for the productivity of the team. If the ScrumMaster truly believes that Scrum is not helping the team, for whatever reason, it is antithetical to Scrum for the ScrumMaster to continue serving in this capacity. If the ScrumMaster is in doubt of the applicability of Scrum as a whole at any given time, this concern needs to be shared with the team and an assessment of whether or not to continue with Scrum may need to be considered. It may be that the ScrumMaster is struggling with understanding how to implement a specific aspect of Scrum in a particular situation and with the help of the team is able to overcome this obstacle. Another possible outcome may be that the ScrumMaster is unable to overcome personal issues with Scrum at which point the team may decide to continue the Scrum implementation without that person’s involvement. Whatever the process for getting there, it is imperative that the ScrumMaster holds this firm belief. Scrum is extremely difficult to do well. Being a ScrumMaster is a very difficult job. If the ScrumMaster does not believe that Scrum will help the team, then the ScrumMaster will not be able to sustain the work of removing obstacles for the team. Instead, shortcuts will be taken, the benefits will not be realized and much effort will be wasted.
