SDLC PM Process Groups Knowledge areas PM Process Groups and Knowledge areas Knowledge Areas Knowledge Areas describe the key common competencies that project managers must develop at any project. • Project integration management is an overarching function that coordinates the work of all other knowledge areas. It affects and is affected by all of the other knowledge areas • Project scope management involves working with all appropriate stakeholders to define, gain written agreement for, and manage all the work required to complete the project successfully. • Project time management includes estimating how long it will take to complete the work, developing an acceptable project schedule given cost-effective use of available resources, and ensuring timely completion of the project SDLC PM Process Groups Knowledge areas PM Process Groups and Knowledge areas Knowledge Areas (cont.2) • Project cost management consists of preparing and managing the budget for the project. • Project quality management ensures that the project will satisfy the stated or implied needs for which it was undertaken. • Project human resource management is concerned with making effective use of the people involved with the project. • Project communications management involves generating, collecting, disseminating, and storing project information . SDLC PM Process Groups Knowledge areas PM Process Groups and Knowledge areas Knowledge Areas (cont.3) • Project risk management includes identifying, analyzing, and responding to uncertain hazards or damages (risks) related to the project. • Project procurement management involves acquiring or procuring goods and services for a project from outside the performing organization. • Project stakeholder management focuses on identifying project stakeholders, understanding their needs and expectations, and engaging them appropriately throughout the project. SDLC PM Process Groups Knowledge areas PM Process Groups and Knowledge areas Knowledge Areas are simply • Integration (The overall ‘How’) • Scope (What is to be produced?) • Time (By when?) • Cost (What is the price?) • Quality (Does it meet stakeholder expectations?) • Human Resources (People) • Communication (Who should know what?) • Risk (What may go wrong?) • Procurement (Who else can do what my team cannot?) • Stakeholder (Who are involved?)

  • SOFTWARE DEVELOPMENT METHODOLOGIES Methodologies
    SOFTWARE DEVELOPMENT METHODOLOGIES Methodologies • Waterfall • Prototype model • Incremental • Iterative • Spiral • RAD Waterfall • Sequential design process • Progress is seen as flowing steadily downwards (like a waterfall) through SDLC Prototyping • Creating prototypes of software applications i.e. incomplete versions of the software program being developed • A prototype typically simulates only a few aspects of, and may be completely different from, the final product. Incremental Build Model • The model is designed, implemented and tested incrementally (a little more is added each time ). • Finished when satisfies all the requirements. • Combines the elements of the waterfall model with the iterative philosophy of prototyping. Iterative and Incremental Development • Iterative and incremental development is any combination of both iterative design or iterative method and incremental build model for development. Incremental vs. Iterative A Bit Different Understanding Effort in Iterative Development Spiral Model • Combining elements of design and prototyping- in-stages • Combines the features of the prototyping and the waterfall model • The spiral model is intended for large, expensive and complicated projects • Advantages of top-down and bottom-up concepts RAD • Minimal planning and fast prototyping. • Developing instead of planning • The lack of pre- planning generally allows software to be written much faster, and makes it easier to change requirements. Agile • Group of software development methods • Based on iterative and incremental development • Most important phrases • self -organizing, cross - functional teams • adaptive planning, • evolutionary development and delivery, • a time-boxed iterative approach, • rapid and flexible response to change. • A conceptual framework • The Agile Manifesto in 2001..

  • System Development Life Cycle Methodology
    2 System Development Life Cycle Methodology Learning Objectives : • To introduce the general concepts of various approaches of systems development, their framework, advantages and disadvantages; • To explain in detail the phases involved in Systems Development Life Cycle(SDLC); • To understand the key issues while acquiring or developing system for achieving goals set; • To discuss in detail various System Development Tools like – DFD, Decision Tree, Flowcharts etc.; and • To understand the auditors’ role in SDLC. 2.1 Introduction Information systems serve many different purposes, ranging from the processing of business transactions - to provide information needed to decide recurring issues, assisting senior officials with difficult strategy formulation, and linking office information and corporate data. But how do such complex information systems come into existence? Of course, through people. Technology has developed at a rapid pace but the most important aspect of any system is human know-how and the use of ideas to harness the computer so that it performs the required tasks. This process is essentially what system development is all about. To be of any use, a computer-based information system must function properly, be easy to use, and suit the organization for which it has been designed. If a system helps people to work more efficiently they will use it. If not, they will surely avoid it. 2.2 System Development Process In business, systems development refers to the process of examining a business situation with the intent of improving it through better procedures and methods. System development can generally be thought of as having two major components : System Analysis and System Design.
