SDLC/Agile Methodology Differences The Systems Development Life Cycle, better known as the SDLC, is an Information System development method which is founded upon its four fundamental phases: * * Planning * Analysis (& Design) * Design * Implementation

Although these four phases are sometimes approached in a few different ways, the basic concept remains the same; each phase of the development method is addressed in a typical SDLC approach. The approach may sometimes be done consecutively, incrementally, or in other manners dependant on the situation. SDLC methodology is better suited for larger projects, in addition to a larger audience. Although this process requires as much input as possible (during the Analysis phase) from people who will work directly with the new system, this same requirement will normally diminish as the development process continues with the rest of the other phases. In comparison, the Agile methodologies are a collection of alternate (more fluid and adaptive) approaches made from several different system development methods. A document by the name of The Agile Manifesto addresses these common aspects of the various methodologies under the Agile Methodologies umbrella. One of the key principles which constitute a specific methodology as part of the Agile Methodology would be that the methodology will be very flexible and adaptive to the current state of the project, instead of dictating which path it will follow. Agile Methodologies are also much better suited for smaller groups of experts which remain actively involved throughout the developmental process.

Best Suited Methodologies When it comes to better fits for the various methodologies, the difference is quite evident. Agile

Geting It Together

...important concept is that there are two types of development methodologies—a structured approach and an object-oriented approach. These are two separate concepts. Projects can be any mix of these two approaches, the approach to the life cycle and the approach to the methodology—predictive with structured, predictive with object-oriented, adaptive with structured, or adaptive with object-oriented. The chapter first presents and explains the differences in the life cycle approach—the predictive and the adaptive approaches. These two approaches are really a continuum and any give project may have elements of both approaches. The predictive approach to the SDLC is used for projects that are well understood and low risk. The adaptive approach to the SDLC is used for projects that are not well understood and are higher risk. Adaptive SDLCs are more iterative and allow the project team to adapt the project to changing circumstances. The other important concept that you should learn from this chapter are the difference between the two main methodologies to system development that are currently used to develop business systems: the structured approach and the object-oriented approach. The object-oriented approach refers to system development using newer object technologies that require a different approach to analysis, design, and programming. Finally the chapter concludes with a discussion of the Agile philosophy and Agile...

...The role and impact of project management in erp implementation Trends and Issues Report The role and impact of project management in erp implementation Trends and Issues Report Thesis Statement and Key Words Thesis Statement The key to success in implementing an Enterprise Resource Planning (ERP) system is to understand an ERP life cycle and methodology throughout the implementation. Systems development theory uses the concept of a lifecycle and stages in the lifecycle to indicate development of information systems. In a system development life cycle (SDLC), complex problems need to be broken up into smaller manageable problems using a systems hierarchy, or project management methodology. This paper will introduce a popular methodology called Agile and why is it so useful compared to traditional methods. In addition, the roles of the project manager in the implementation process, how does he/she manage to help the company succeed will also be discussed. Key Words Enterprise Resource Planning Project Management Systems Development Life Cycle Methodologies Agile Risk management Adapt changes Overview Introduction Enterprise Resource Planning (ERP) is business process management software that allows an organization to use a system of integrated applications to manage many back office functions related to technology, services and human resources - (Beal, 2014).

Hoosier Burger

...SDLC Approach Hoosier Burger, a restaurant owned by Bob and Thelma Mellankamp, is running the business with errors occurring frequently because of the nonexistence of an organizational information system. The systems analysis consultant that is hired to help Hoosier Burger should utilize the Systems Development Life Cycle (SDLC) methodologies to develop and support the organization’s information system. There are four key steps to the SDLC: (1) planning and selection, (2) analysis, (3) design, and (4) implementation and operation. The first phase in the SDLC is when the organization’s total information system needs are analyzed and arranged. The result of this phase is a potential information systems project is identified. The systems analyst prioritizes and translates the needs of Hoosier Burger and translates the needs into a written plan. The fact of the matter is that Hoosier Burger is processing business by a method of paper-based system, suggesting a valid argument for continuing with the SDLC approach. Systems analysis, the second phase, is when the analyst will thoroughly study the organization’s current procedures to perform the tasks. The analyst must work with users to determine what the users want from the proposed system. For Hoosier Burger, the tasks are inventory control, customer ordering, and management reporting. The systems analysis phase of SDLC is when an alternative replacement system is proposed. Phase three is systems design. This is when...

Kral BSA/385 December 9, 2013 Andrew Carpenter Development Methodologies A development methodology is the framework that a developer or team uses to structure, plan, and control the process of developing a system or application. There is a wide variety of methodologies to choose from, each with its own strengths and weaknesses. Two of the more common and most used methodologies are the Waterfall method, and the agile method. This paper will focus on these two methods giving detailed descriptions, as well as advantages and disadvantages. Testing for each method will also be covered. The Waterfall Method The Waterfall Method of development is a linear-sequential life cycle model. This method is very simple to use and understand. In this model, each phase needs to be completed before the next phase can begin, phases cannot overlap, and once you finish a phase you cannot go back. A good example of this process is a literal waterfall flowing down the side of a mountain. "Once the water begins to flow over the mountain, it will hit each rock and continue down. The water can never go in the opposite direction." (Rouse, 2007) This is displayed in the following chart: The waterfall method allows for departmentalization and easy managerial control. "A schedule can be set with deadlines for each stage of development and a product can proceed through the development process like a car in a carwash, and theoretically...

...System Development Lift Circle (SDLC) SDLC is a process used by software industry to design, develop, and test high quality software. It consists of a detailed plan describing to develop, maintain, replace and alter the specific software. There are many different system development models which includes water fall, spiral and chaos models. Waterfall model is the earliest SDLC approach that was used for software development. In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. The outcome of one phrase acts as the input for the next phrase sequentially. Following is a diagrammatic representation of different phases of waterfall model. Waterfall Model * Requirement Analysis: also call system request which describe all possible requirements of the system. * System Design: create a physical model that will satisfy all documented requirements. It also helps in defining overall system architecture. * Implementation:  With inputs from system design, the system is first developed in small programs called units which will be developed and tested in the next phase. * Testing: Each unit will be test for any faults and failures before integrating into system. At the conclusion of this phrase, the system is ready for use. * Development of system: the product is deployed in the customer environment or released into the market. * Maintenance: There will have issues which come...

...MAJOR pROCESS IN THE SDLC April 22, 2012 Major Process In chapter 1, Pfleeger briefly described nine stages or activities of a software development and engineering process. In this paper we will explore the nine stages of the systems development life cycle and its sub processes further. 1. Requirements analysis and definition is the first stage in the systems engineering and software development process. This stage breaks down functional and non-functional requirements into a basic design in order to provide a clear system development process framework. (DNB, 2010) a) Interviews: Interviews with clients and stakeholder assist defining system requirements by obtaining system needs. b) Documentation: The information gathered during the interview process should be documented and put together so that it can be reviewed collectively and used as the base information to derive the requirements by system analysts. c) Define Project Terms and Vocabulary: Define Requirements, System Environment, the definition of general terms and concepts should be properly communicated to the stakeholders, with various backgrounds and knowledge levels. .  d) Define Requirements, System Environment, Development Tools, and Development Language: This sub process may be the most important process because it chooses detailed requirements from the interview data to be used l in the system design process. The agile method doesn’t spend as much time with...

...needs to examine the ways in which people in the organisation perceive their world. The key point is that meanings and purposes is essential in order to arrive at the right system which will support the data processing. (Checkland & Holwell, 1998:110-113) Figure: SCRUM Agile Process for Globally Distributed Teams The history of systems development Systems development was seen in the earlier years as a predominantly practical, technical process that led to a problem-solving philosophy accepted by computer professionals as a purely technical process aimed at solving problems which are defined in mostly technical terms. This mechanistic bias in the systems development process can be the leading factor in information systems failure. (Maguire, 2000:232-236) Agile Development The philosophy of agile development The philosophy of agile is defined in a Manifesto. In this Manifesto the values are outlined that should be in agile development. These values state that individuals and their interactions must be more important than processes and tools. How the SDLC and Agile methods compare In outline the distinction between the SDLC and Agile methods can be formulated as follows: The SDLC The SDLC has a technical bias. It...

...development life cycle (SDLC). These phases include systems planning and selection, systems analysis, system design, and system implementation and operation. The first phase is system planning and selection, which identifies the need for building information systems. This phase also covers the scope, cost, and schedule of building information systems. The second phase is the systems analysis phase, which is the actual study of the current procedures and the requirements needed. The third phase is system design, which is broken into two parts called the logical design and physical design. The logical design concentrates on the business aspect of the system, whereas the physical design pertains to the technical specifications. Finally, the fourth phase is the system implementation and operation phase. This phase implements the system by installing the hardware or software of the system. Other forms of implementation include programming, user training, and documentation. 2.

...CHAPTER 2 SYSTEM DEVELOPMENT LIFE CYCLE TYPES OF INFORMATION SYSTEM Transaction Processing Systems A transaction processing system provides a way to collect, process, store, display modify or cancel transactions. Most of these systems allow multiple transactions to take place simultaneously. The data that this system collects is usually stored in databases which can be used to produce reports such as billing, wages, inventory summaries, manufacturing schedules, or check registers. Management Information Systems A management information system is an information system that uses the data collected by the transaction processing system and uses this data to create reports in a way that managers can use it to make routine business decisions in response to problems. Some of the reports that this information system creates are summary, exception and ad hoc reports. All this is done to increase the efficiency of managerial activity. Decision Support Systems A decision support system helps make decisions by working and analyzing data that can generate statistical projections and data models. This system gives support rather than replacing a managers judgement while improving the quality of a managers decision. A DSS helps solve problems while using external data. Expert Systems and Neutral Networks An expert system, also known as a knowledge-based system, is a computer system that is designed to analyze data and produce recommendations, diagnosis and decisions that are controlled...
