Concept testing and minimum viable product (MVP) are key stages in the product innovation process. Product leaders face a dilemma: If they don’t engage their security peers at these stages, they could make vital decisions that weaken security down the road; however, over-engineering security for the MVP will slow innovation and destroy trust. Minimum viable security (MVS) offers a way to address security in early-stage concept testing without slowing down the product team. Security leaders should use this report to make the business case for MVS to their teams and the product organization to support their involvement in the early stages of product innovation.
