The systems development life cycle is important because it has six important phases that are essential for developers such as planning, analysis, design, and implementation.
1. Planning
The feasibility study is sometimes used to present the project to upper management to get the approval and to have funding. Projects are evaluated in three main areas of feasibility: economical, organizational and technical.
2. Analysis
The main objective of systems analysis is to determine where the problems in an attempt to help fix the system.
3. Design
In systems, design functions and operations are described in detail, including screen layouts, business rules, process diagrams and other documentation. The output of this stage will describe the new systems as a collection of models or subsystems.
4. Build or coding
Modular and subsystem programming code will be accomplished during this stage. Unit testing and module testing are done in this stage by the developers. This stage is intermingled with the next in that individual modules will need testing before integration to the main project.
5. Testing
The code must be tested at various levels in software testing. Unit, system and user acceptance testings are often performed.
There are many types of testing such as: Data testing, integration testing, user acceptance testing, performance testing and more.
6. Operations and maintenance
The deployment of the system includes changes and enhancements before the sunset of the system. Maintaining the system is an important aspect of SDLC. As key personnel change positions in the organization, new changes will be implemented, which will require system updates.
Some examples that were developed using SDLC methodology, would be telecom online payment systems, banking online services, and M-Net mobile payment services.

Six Thinking Hats

...a large quantity of steel, manufacture and sell both steel and plastic rings or continue to manufacture and sell steel until their stock of steel is used up. In order to make this decision, it is essential that Lawrence implement critical thinking and decision making strategies among other resources. There are a lot of details to consider in regards to this decision, such as the value of the remaining steel, the amount of steel rings on hand, the cost of the industrial machines, and how much money would be needed to produce the plastic rings inclusive of the necessary tools and equipment. With gathering all the necessary information Lawrence would be using the white hat from the Six Thinking Hats process, an important and prevailing technique that allows a person to look at decisions from a number of important perspectives. This procedure provides a well-rounded view of a situation, forcing you to move outside your habitual thinking style. Colored hats are used as metaphors for each direction. Switching to a direction is symbolized by the act of putting on a colored hat, either literally or metaphorically. These metaphors allow for a more complete and elaborate separation of the thinking directions. Information, Emotions, Discernment, Optimistic Response, and Creativity, The six thinking hats indicate problems and solutions about an idea the thinker may come up with. If Lawrence Bridgeman puts this process into practice he will encourage creative thinking within......

Summary VII. Recommendation VIII. Conclusion Introduction: As our economic future hinges on the ability for organizations to cut cost and improve the quality of their products and services as well as develop new ideas in order to stay competitive, managers today still rely on concepts that stay constant throughout the years, those concepts are Six and Lean Sigma. These concepts are widely used by many organizations as an approach or a process for investigation to achieve better results and improvement in their daily operations, services and products. Throughout this research paper the focus will be centered on the history of Six and Lean Sigma, how both concepts helped revolutionize the fields of quality control and process management, Lean and Six Sigma’s emphasis on collective efforts and teamwork to the applied steps taken. Furthermore, the research paper will provide tables and examples of how both concepts are applied to organizations. History of Lean and Six Sigma: The origins of Six Sigma can be traced as far back as 1777 when Carl Frederick Gauss first introduced the concept as a measurement tool of the normal curve. In the 1920's the word 'sigma' was used by mathematicians and engineers as a symbol for a unit of measurement in......

...MANAGING THE DEVELOPMENT OF LARGE SOFTWARE SYSTEMS Dr. Winston W. Rovce INTRODUCTION l am going to describe my pe,-.~onal views about managing large software developments. I have had various assignments during the past nit,.: years, mostly concerned with the development of software packages for spacecraft mission planning, commanding and post-flight analysis. In these assignments I have experienced different degrees of successwith respect to arriving at an operational state, on-time, and within costs. I have become prejudiced by my experiences and I am going to relate some of these prejudices in this presentation. COMPUTER PROGRAM DEVELOPMENT FUNCTIONS There are two essential steps common to all computer program developments, regardless of size or complexity. There is first an analysis step, followed second by a coding step as depicted in Figure 1. This sort of very simple implementation concept is in fact all that is required if the effort is sufficiently small and if the final product is to be operated by those who built it - as is typically done with computer programs for internal use. It is also the kind of development effort for which most customers are happy to pay, since both steps involve genuinely creative work which directly contributes to the usefulness of the final product. An implementation plan to manufacture 13rger software systems, and keyed only to these steps, however, is doomed • tofailure. Many additional development steps are required, none......

Six Sigma Quality Paper

...Six Sigma – A Management Philosophy Executive Summary I chose this topic because it was something that I’ve heard a great deal about, but have very little experience with. At my company, MetLife, there has been some recent investigation into Six Sigma and how it can help improve our Financial Reporting processes. While Six Sigma can involve some very complex statistical theory, especially in the world of manufacturing, I wanted to concentrate more on the Management philosophy and how it can implemented in a service type organization. Introduction History After World War II, the Japanese were left to rebuild their destroyed economy. They had to figure out a way to rebuild with very little resources other than human capital. Japanese leaders realized that to compete in the world market they must make drastic changes to quality management. (Kumar, 2006) Throughout the 50’s and 60’s, with the help of quality gurus like Deming and Juran, the Japanese made rapid improvements in quality of the production of goods and services. Meanwhile, the United States did very little to change their methods of operation. At the time, the United States was the main source for goods and services in the western world. There was very little incentive to concentrate on expensive quality improvement projects that would hurt the short-term bottom line. Instead, the focus was on production and performance. (Kumar, 2006). By the early 80’s, Japan had solidified......

...Six Sigma and TQM/CQI Impact on U.S. Healthcare Regla Perez Keiser University Dr. Mary Granoff HSM691-G3 August 23, 2014 Introduction The concept of Six Sigma can be traced as far back as the late 1700’s when Carl Frederick Gauss introduced the normal curve. It wasn’t until the 1920’s when Walter Schewart was able to pinpoint the distance from the mean where a process which shows evidence of a defect or negative result, can be changed or corrected. However, it was Motorola’s Chairman Bob Galvin in the early 1980’s who after trying the traditional ways to measure defects realized they did not provide sufficient details that would identify the true effects of the defects within the manufacturer’s organization. It was at this at this time he introduced the concept of Six Sigma and helped the company’s bottom line which had not been a profitable one. Once the application of the Six Sigma concept became public, and the positive impact it had on Motorola’s bottom line, many other businesses wanted to learn about this concept. The impact of this concept was such that many of the executives of some of the largest companies have applied Six Sigma’s methodology to refocus their business on the road to profitability. What is Six Sigma? The concept of Six Sigma can be defined as an efficient methodology to problem solving which contributes to the improvement of performance of an organization or business. ......

...Within this essay I am going to critically analyse Six Sigma concepts in relation to contemporary software development projects. To do this I am going to research different topics of the Six Sigma focused on software development project. To begin with I am going to give an overview of the history of Six Sigma focusing on explaining aspects of its methodological development and give a detailed description of contemporary Six Sigma methodology. Finally I am going to analyse the central concepts of contemporary Six Sigma methodology and then conclude all of my work together and discuss the principal arguments. Six sigma is a methodology used to focus an organization on reducing variations and errors in processes and driving quality improvement. Developed by Motorola Inc in the USA in 1986, it became well known in the 90’s, when GE CEO Jack Welch evangelized it. Six sigma is now according to many business development and quality improvement experts, the most popular management methodology in history. Six sigma aims to maximise customer satisfaction and minimise defects. In statistical terms, the purpose of six sigma is to reduce the process variation so that virtually all the products or services provided meet exceeded customer expectations. The standard metric for Six Sigma is 3.4 defects per million opportunities. For example for every 1 million transactions that go through a system, there will be 3.4 errors and still achieve six sigmas. Therefore this process has so few......

...archive of this journal is available at TQM 19,1 6 Dynamics of organizational learning and continuous improvement in six sigma implementation Taina Savolainen Department of Business and Economics, University of Joensuu, Joensuu, Finland, and Arto Haikonen Genworth Financial, Helsinki, Finland Abstract Purpose – The purpose of this paper is to examine the dynamics of organizational learning and continuous improvement (CI) in the context six sigma implementation in business organizations operating in multicultural environments. Design/methodology/approach – A specific research question is: does learning mechanisms and continuous improvement practices support each other and how, and what type of learning can be identified in the improvement of business processes. The question is linked to one of the fundamental issues currently discussed in the field of organizational learning; how do organizations get “from here to there”, in other words, what is the dynamics of the processes of learning and how progressive learning is achieved. A case study of a few Finnish companies is made and a procedural implementation model is applied. Findings – The findings suggest that the learning process is characterized by measurement, detection and correction of errors, and cost reduction. In six sigma implementation, learning is a single-loop type of learning. It is an incremental change process which reminds a technical variant of the learning......

...provide a series of recommendations that, if implemented, will assist with the fictional organizational goal that has been requested by the department managers at this company. Principals of Lean Manufacturing Lean Manufacturing is defined as a production practice that uses less and fewer resources than traditional manufacturing. The primary objective of implementation of lean processes is to eliminate any element of the process that does not add value and striving for perfection with zero defects and zero inventories. (Lynch, 2005) There are various principals to lean manufacturing that can be applied to any area of an organization to realize the process improvement in the assignment below I will discuss three examples 5s, Six Sigma and Kaizen. Process Improvement-5S 5S is a system that reduces waste and optimizes productivity through an orderly workplace and using visual cues to obtain more consistent results of the operation. Created first by Toyota Production Company, a Japanese based company, the five pillars in this process are: Sort (Seiri) Eliminating unnecessary item from the workplace that is not needed for the current operation. Set in order (Seiton) Creating efficient and effective storage and labeling methods that improve identification of items for use and store. Shine (Seiso) – Once clutter is eliminated and remaining items are stored, the Shine step in this process thoroughly cleans the whole area. Working in a clean environment......

...development for many companies. The implementation of programs such as Total Quality Management (TQM) and Six Sigma help companies increase production and quality control, evaluate employee performance, and receive customer feedback. The Internet is also a magnificent tool that allows businesses and customers to communicate and help improve the performance of the company. The goal of most companies is to provide products and services that meet the quality expectations of their customers. Programs such as Six Sigma and TQM are essential for companies to compete with one another. Meeting the standards of customers is critical for businesses to succeed, and companies must continually improve on their products and services to meet the increasing demand of consumers. “Quality is the most important aspect of products and services, and the basis for the purchase of consumers. It has been reported that the quality movement has one core idea, and that is, goods and services must achieve the highest attainable quality, or nothing else will do. Thus, the past decade or so has seen the rise of a philosophy aimed at maximizing organizational quality and understanding it” (Connor, 1997). While there are other considerations, such as price, delivery, and flexibility, quality is still of utmost importance. This paper will discuss the advantages and disadvantages of implementing such practices as Six Sigma and Total Quality Management. Is one more beneficial than the other is, or is it......

...six sigma six sigma training, history, definitions - six sigma and quality management glossary Six Sigma is now according to many business development and quality improvement experts, the most popular management methodology in history. Six Sigma is certainly a very big industry in its own right, and Six Sigma is now an enormous 'brand' in the world of corporate development. Six Sigma began in 1986 as a statistically-based method to reduce variation in electronic manufacturing processes in Motorola Inc in the USA. Today, twenty-something years on, Six Sigma is used as an all-encompassing business performance methodology, all over the world, in organizations as diverse as local government departments, prisons, hospitals, the armed forces, banks, and multi-nationals corporations. While Six Sigma implementation continues apace in many of the world's largest corporations, many organizations and suppliers in the consulting and training communities have also seized on the Six Sigma concept, to package and provide all sorts of Six Sigma 'branded' training products and consultancy and services. Six Sigma has also spawned manay and various business books on the subject. Six Sigma, it might seem, is taking over the world. Interestingly while Six Sigma has become a very widely used 'generic' term, the name Six Sigma is actually a registered trademark of Motorola Inc., in the USA, who first pioneered Six Sigma methods in the 1980's. The original and technically correct spelling seems to......
