Open Discussion on Project Planning Planning in an Agile Environment Key Tenets  Planning should focus strongly on the near term  Eliminate waste caused by planning for eventualities that never come circumstances o Agile methodology does not force programs to establish their full scope, requirements, and design at the start, but assumes that these will change over time. Even so, the program must maintain a applications o Replace comprehensive Preliminary Design Reviews (PDRs) and Critical Design Reviews (CDRs) with more frequent and incremental design reviews during the release planning phases. To demonstrate

computing, edge computing, and embedded deployment. It provides a secure, stable, and easy-to-use open source OS that is compatible with multiple computing architectures. openEuler suits operational and communications technology (ICT). The openEuler open source community is a portal available to global developers, with the goal of building an open, diversified, and architecture-inclusive software history of helping enterprises develop their software, hardware, and applications. The openEuler open source community was officially established on December 31, 2019, with the original focus of innovating

users throughout development to ensure high operational value Agile practices integrate planning, design, development, and testing into an iterative lifecycle to deliver software at frequent intervals the requirements, systems engineering, contracting, cost estimating, and testing communities to design processes around short releases. Acquisition executives must also streamline the decision process their insights to help program managers better understand Agile fundamentals, how to structure and design a program to enable Agile development, and how to partner with the process owners of various acquisition
