Customer collaboration is vital to Agile projects. Through a Grounded Theory study of New Zealand and Indian Agile teams we discovered that lack of customer involvement was causing problems in gathering and clarifying requirements, loss of productivity, and business loss. “Agile Undercover” allows development teams to practice Agile despite insufficient or ineffective customer involvement. We p...

Agile Methods are creating a buzz in the software development community, drawing their fair share of advocates and opponents. While some people consider agile methods the best thing that has happened to software development in recent years, other people view them as a backlash to software engineering and compare them to hacking. The aim of this chapter is to introduce the reader to agile method...

background: taxi drivers have the most important role in the public transport services. they are exposed to various harmful agents and occupational hazards. noise is a harmful occupational factors and hearing loss is its most important effect. protection of drivers against hearing loss is essential. this study was performed to determine the prevalence of hearing loss among taxi and agency drive...

Software developers can use agile software development methods to build secure information systems. Current agile methods have few explicit security features. While several discrete security methods can supplement agile methods, few of these integrate seamlessly into other software development methods. Because of the severe constraints imposed by agile methods, these discrete security technique...

Unlike traditional software development methods, agile methods are marked by extensive collaboration, i.e. face-to-face communication. Although claimed to be beneficial, the software development community as a whole is still unfamiliar with the role of the requirements engineering practices in agile methods. The term ‘‘agile requirements engineering’’ is used to define the ‘‘agile way’’ of plan...

Agile development practices focus on developing and delivering working software systems in small iterations with minimal documentation. However, locally project focused agile practices overlook the need for holistic enterprise architecture. Lack of enterprise architecture in agile, especially in the large agile environments, may lead to a number of problems such as technical debt, unnecessary r...

Agile methodologies are great software development methodologies. No doubt that these methodologies have widespread reputation. The core of agile methodologies is people. Customer and each team member in agile development teams are the key success or failure factor in agile process. In this paper authors demonstrate strength and weakness points in agile methodologies. Also authors demonstrate h...

The failure rate for vascular interventions (vein bypass grafting, arterial angioplasty/stenting) remains unacceptably high. Over the past two decades, researchers have applied a wide variety of approaches to investigate the primary failure mechanisms, neointimal hyperplasia and aberrant remodeling of the wall, in an effort to identify novel therapeutic strategies. Despite incremental progress,...

While six sigma quality has long been achieved in other industries, it is rarely seen in the pharmaceutical sector. However, consumers and patients deserve six sigma quality pharmaceuticals with minimal risks of shortages or recalls. We propose that the future of pharmaceutical quality is six sigma, meaning that no more than 3.4 defects occur per million opportunities. We discuss the path to ge...
