This paper describes an empirical study of effort estimation in agile software development. Estimated effort and actual effort of a 46-iteration project are collected and analyzed. The results show that estimation in agile development is more accurate than that in traditional development even though agile developers still underestimate the effort. However, estimation accuracy is not improved ov...

Gaining maximum benefit of Lean and Agile methods requires a thorough understanding of their assumptions regarding culture, mindset, and values. This paper examines the value system structure of experienced developers working with Lean and Agile methods, and compares it to universal human values and individual personality. We developed and deployed an online survey on Lean and Agile values, wit...

Agile methods are a departure from plan-driven traditional approaches, where the focus is on generating early releases of working software using collaborative techniques, code refactoring, and on-site customer involvement. Research and surveys have shown that agile methodologies are an efficient way of producing software with significant advantages in production costs, time-to-market, complexit...

Agile methodologies were introduced in 2001. Since this time, practitioners have applied Agile methodologies to many delivery disciplines. This article explores the application of Agile methodologies and principles to business intelligence delivery and how Agile has changed with the evolution of business intelligence. Business intelligence has evolved because the amount of data generated throug...

The agile principles applied to software engineering include iterative and incremental development, frequent releases of software, direct stakeholder involvement, minimal documentation and welcome changing requirements even late in the development cycle. The Agile Requirements Engineering applies the above mentioned principles to the Requirements Engineering process. Agile Requirements Engineer...

Agile methods have become popular in recent years because the success rate of project development using Agile methods is better than structured design methods. Nevertheless, less than 50 percent of projects implemented using Agile methods are considered successful, and selecting the wrong Agile method is one of the reasons for project failure. Selecting the most appropriate Agile method is a ch...

Agile Software Development methods have been increasingly adopted worldwide and became one of the mainstream software development approaches. Agile methods have also had an impact on software engineering education with universities adapting their courses to accommodate this new point of view of software development. Software engineering research has tried to evaluate the impact of agile methods...

Modern manufacturing is under ever increasing pressure to develop solutions for highly complex tasks. In order to maintain the business survival in a highly competitive environment, it is vital to obtain customer satisfaction, which requires developing products with shorter lifecycles and higher quality meanwhile to reduce the production costs. In order to achieve such objectives a paradigm has...

Agent based modeling and simulation consider the behavior of agents acting in a system. The agents' interactions result in changing the agent’s behavior, the whole agent based system, and its environment. In this study, the manufacturing, sale, and receiving orders behaviors pertinent to manufacturing and sale agents acting across a pharmaceutical supply chain of an Iranian manufacturing medici...

Nowadays, in turbulent and violate global markets an Agile Supply Chain (ASC) network is frequently considered as a dominant competitive advantage for survival. To achieve the competitive advantage, companies must align with suppliers and customers to streamline operations, as well as agility beyond individual companies. There are many definitions and models about agile supply chain and most of...
