No Silver Bullet – Essence and Accident in Software Engineering Mike Ballou“There is no single development, in either technology or management technique, which by itself promises even one order-of- in simplicity.”Abstract “All software construction involves essential tasks, the fashioning of the complex conceptual structures that compose the abstract software entity, and accidental tasks, the onto machine languages within space and speed constraints.”Abstract “Most of the big gains in software productivity have come from removing artificial barriers that have made the accidental tasks inordinately

to succeed in an increasingly complex environment. Agile has emerged as the leading industry software development methodology, and has seen growing adoption across the DoD and other federal agencies these objectives through:  Focusing on small, frequent capability releases  Valuing working software over comprehensive documentation  Responding rapidly to changes in operations, technology, practices integrate planning, design, development, and testing into an iterative lifecycle to deliver software at frequent intervals. Developers can demonstrate interim capabilities to users and stakeholders

Stanford University… 1: AI ‘Winter’ was a term used by Nils J. Nilsson, the Kumagai Professor of Engineering in computer science at Stanford University, to describe the period during which AI continued to hypothetical endpoint, but as a reachable threshold. If / when achieved, AGI would redefine what software (and related hardware) can do. Rather than executing pre-programmed tasks, AGI systems would understand understand goals, generate plans, and self-correct in real time. They could drive research, engineering, education, and logistics workflows with little to no human oversight – handling ambiguity and novelty
