2/7/25 WHAT IS SOFTWARE DESIGN SOFTWARE DESIGN is the process of planning and problem solving Introduction to to create a software solution. It SOFTWARE DESIGN involves defining the software's characteristics and goals, and then developing the software based on that plan. 1 2 NATURE OF SOFTWARE DESIGN The software is an instruction or computer program that when executed provides desired features, function, and performance. A data KEY MILESTONES OF structure that enables the program to SOFTWARE ENGINEERING adequately manipulate information and documents that describe the operation and use of the program. 3 4 First electronic computer was developed. Primarily First electronic computer was developed. Primarily designed for Military use during world war 2. designed for Military use during world war 2. Electronic Numerical Integrator and Computer (ENIAC) Electronic Numerical Integrator and Computer developed in 1945. (ENIAC) developed in 1945. One of the first software program was written by Grace Hopper. Who worked on the Harvard Mark I computer known as Harmonic Series First Programming language was developed called “FORTRAN” (FORmula TRANslation) by John Backus at IBM COBOL (Common Business Oriented Language) was created in 1959 at the UNIVAC corporation 5 6 1  2/7/25 “Software Crisis” for demand software applications increased but supply of trained software developer failed to keep pace. COBOL 1975 Frederick Brooks published the book “The Mythical Man Month” helped to establish a framework for understanding software development challenges. The Term “Software Engineering” was coined by Margaret Hamilton, who led the team that IEEE Software Engineering Standards Committee was developed the software for Apollo space program. established. Created standards such as IEEE730 for QA standard, IEEE 828 for configuration management, IEEE1016 QA metrics. 7 8 The significant period of software evolution. This period introduce new approached in software development such as DevOps and CI/CD (Continues Integration/Continues Delivery The rise of Agile Manifesto and Agile development CHARACTERISTICS methodologies.

Quality Management HR Management System System (QMS) Project Management System Database Enterprise Resource Planning 23 24 4  2/7/25 WHAT IS QMS Quality Management System At the organizational level, quality management is concerned with establishing a framework of organizational processes and standards that will lead to A quality management system (QMS) is a high quality software. This means that the quality formalized system that defines and management team should take responsibility for defining the software development processes to be used and documents an organization’s processes, standards that should apply to the software and related procedures, and responsibilities for achieving documentation, including the system requirements, quality policies, practices, and objectives. design, and code. 25 26 ISO 9001 is a framework that defines how to establish, implement, maintain, and improve a Ensure the quality of their products and services is consistent QMS. It's based on seven quality management principles, including customer focus, continual Reduce the chance of product faults and recalls improvement, and evidence-based decision ISO Goal & making.
