The Sprint Review meeting supports the Scrum value of Openness and the principle of inspect and adapt. This rule of Scrum also aligns with the Agile Manifesto principles “The most efficient and effective method of conveying information to and within a development team is face-to-face conversation” and “Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.” In-person attendance of all Scrum Team members allows for the fullest level of openness among Team Members and effective communication of feedback from stakeholders reviewing the product increment. If even one team member attempts to attend this meeting by any other means, either by phone or even video conferencing, efficiency and effectiveness of the openness and inspect and adapt becomes compromised. Compromise on these principles yields compromised collective ownership. The successful delivery of the valuable software requires full commitment on the part of the whole team. Lack of in-person participation increases the likelihood that the team will fail to deliver on its Goal because the openness and inspect and adapt will lack effectiveness.
The ScrumMaster organizes and facilitates the Scrum meetings, including the Sprint Review. The ScrumMaster ensures that all the stakeholders of the Scrum Team and its product are invited to the Sprint Review. The list of stakeholders invited should include, most importantly, end users of the product and / or actual external customers who would buy the product. The Scrum Team presents the product increment during the demo portion of the Sprint Review. This presentation allows the stakeholders to give immediate feedback on the product increment including new functionality, quality, and desired future direction. If the stakeholders are not universally invited, then it is possible that important feedback will be lacking and the Product Owner will create a sub-optimal Product Backlog. One significant benefit of having a broad group of stakeholders attend is that it is highly motivating to the Scrum Team to receive direct feedback every Sprint. This feedback is only possible if all the stakeholders are invited every Sprint.
