A software process model is an abstract representation of a process. The articulation of these models in the twentieth century has brought unexampled changes to the field of software engineering. An alternative model is proposed for large scale software development for products and services with high quality expectations. It would be based on investing up front in the Software Architecture of the system, designing with software product monitoring and alerting logic in place, end-to-end user experience, experimentation and quality of service using PY principles. The basic idea behind developing this model is to have high quality software products and services that can be developed faster, cheaper and in a better way. It can scale with demand in various scenarios, can deliver an outstanding user experience and be failing safe for SDLC bottlenecks which arise in both conventional and the agile software development. Accordingly, product monitoring phase is important to deliver the quality products which require more alerts about the progress and status of the works in day by day. This alert can be done by leveraging the principles of Poka-Yoke which can make alarm to the management.
