1 Comparison of the waterfall and agile approach and its impact on the project success Traditional waterfall project management has been used for many years. However, the projects which are based on waterfall methodologies often face a dilemma of time delay or over budget. As a result, stakeholders are often disappointed about the fact that the time delay, in one way or another, will affect their benefits. To make matters worse, in some cases, the quality of the project will deteriorate because the team follows an ineffective waterfall process. For example, the customer says that they want you to build the software ‘KAILE’, but when the project has almost been completed and the team has already started to set the plan for their holidays, …show more content…
Firstly, the Adobe system, an agile building tool, was introduced to the company in 2012. The new tool could help the team to add new modules on the already existing software without the compromising its function, which is shown in Figure 3, and more importantly, the team did not need to start the process from the beginning as they normally had done in the past ten years. Figure 3. The new agile building tool (Casey and Matt M 2013).
Secondly, a hybrid team was created to work in the same place. This facilitated the communication between team members from two different teams---development team and marketing team, and helped them save a lot of time compared with using e-mails to communicate with each other. As a result, a 300% increase had been seen in productivity. More importantly, it allowed the company to spend more time on setting the strategy for the future, and communicating with their customers (Casey and Matt M 2013).
The success of this case is mainly because the company has recognized that delivering working software to their customers by using the agile approach is the key to keep them thriving in the future industry, and this can be achieved by working together and collaborating with their
The concept of agile management enables the program to meet its needs and provides a value for business effectively and efficiently, unlike the traditional project management which was highly based
Customer satisfaction is the important part in agile development and it is found by direct contact with the customers.
The increasing number of knowledge intensive research and development companies have turned to virtual teams in the recent past in order for them to generate the greatest competitive advantage from limited resources and labor. The geographically distributed teams must communicate via technology, and this has grown in prevalence as compared to the traditional teams in which all members were collocated and communicate face to face. Thus many organizations turn to virtual teams to reduce operational costs, embracing faster problem solving and innovate.
For more than 25 years, The Little Black Book of Project Management has been introducing project managers to the incredibly effective and logical project management skill and methods to help them achieve their goal. This book has been flooded with very nee project management techniques as well as the latest standards of the Project management body of Knowledge (PMBOK) .accepted by PMI (Project Management Institute).
When comparing and contrasting waterfall and agile, they both use the same type of building blocks for the project: scope, cost, schedule and performance. They both also analyze, design, build, test, and deploy the requirement needed for the end result. The difference in these terms for each method is that when using waterfall for scope, cost, schedule, and performance, it sets the scope up front and then allows the cost, schedule, and performance to change depending on what is needed. An agile method will set the cost, schedule, and performance upfront and then have the scope vary, depending on what the company’s requests are after a working prototype. The waterfall is an iterative method meaning the next step cannot begin until the current one is completed. Once the current step is completed, it cannot be revised in anyway unless the project is scrapped and begin again. If the waterfall method is chosen, then the project team
The projects in today’s world are given a lot of importance and it will continue to grow in the coming years. There are a lot of companies which do not have production, but all of them do have projects. There are a lot of books which have been published on which related to planning and managing the projects. The one of the most important one was published by the author Eli Goldratt in his book ‘Critical chain’. This book basically talks and shows how the application of theory of constraints in the field of project management. The novel is basically based on one of the MBA classes in America where a number of ideas are developed in discussions among the students and the lecturers. The lecturer is basically fighting for a tenure with the president of the university who expects a downturn in the executive MBA. The lecturer who teaches project management has a word with one the senior colleagues and project management was the right topic to teach. There were three students who were placed in the project management team of their company which manufactures electronic products. The students are enrolled in this MBA class along with other students, here they discover a new approach to project management which is known as the
Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change.
Since first taking the quiz “How Good Are Your Project Management Skills?” until now, can you identify areas of growth or knowledge regarding project management specifically, or leadership in general? Do you find yourself giving more consideration to particular areas, principles, or practices (e.g. scheduling, scope management, communication styles, etc.)?
A Project Methodology can be defined as a collection of appropriate, relevant techniques which helps to make the organizational outcomes faster and cheaper by forecasting the resource requirements on priority efforts, by enhancing the skills and performance of project members, by
The methods of communicating for a virtual team consist of different tools than used by a traditional team because “…awareness of others’ activities is more difficult and requires some degree of technological intervention” (Fussell et.al., 1998, p. 276). A virtual team needs to use alternative tools because it has members working from different geographical areas and possibly at different times. A traditional team meets face to face, whereas a virtual team needs the use of technology to operate and interact efficiently. Teleconferencing, video conferencing, faxing, e-mail, and instant messaging are some of the tools available to a virtual team.
Project management is said to be completed within time when it completed within the “triple constraints”: cost, time and quality. And in a lot of causes, one them is sacrificed so as to meet the other two. Project managers prioritize which ones are the most important.
The topic of my group (group 4) was “How to totally float through your project for free” and the presentation was held by Roger Goodman who works for PMI NZ and Ernst & Young supply chain management with many years of working experience in many different countries such as Saudi Arabia and China.
The impact of technology on team functioning within the organization Technology has made the world smaller and has brought the people closer around the world (Burke and Cooper, 2007). The use of technologies and upcoming new technologies, ASD (Private) Limited can improve the team functioning. As technology brings dramatic advancement, the teams must update and maintain the awareness to make its factors effectively. The organization can make use of the most common type of technologies are like e-mails, mobile phone, groupware and computers which can improve the team functions more effectively.
What is the waterfall methodology? According to several software engineering sites, the waterfall methodology is also known as the linear-sequential life cycle model and also known as the traditional approach to software development. The waterfall model is as follows: Requirement of gathering and analysis, flowing down to, System design, then flowing down to Implementation, followed by Testing, and then Deployment of the system, and the final phase of Maintenance. The idea of the waterfall approach is that once a phase is completed, the process continues to move down the chain until all of the phases are completed and there is a product to deliver; the method is unidirectional. The waterfall approach is known for not allowing changes to be implemented passed the requirement gathering and analysis phase.
The Iterative development process was established due to the problems experienced with the Waterfall system process. In this case the project is divided into small manageable parts. Design results are available earlier in the process providing valuable feedback for the next process step. Once individual process steps are completed they can go into production immediately and not delayed till the last completed process as demonstrated in the waterfall model.
