Agility versus discipline: Is reconciliation possible?

Software development methodologies have been considered as essential to the production of high quality software, especially on time and within budget. During the last decade, a new school of practice that labels itself as the agile development school has emerged with a set of concepts that can be seen as diametrically opposed to the tenets of traditional methodologies. Promising effectiveness and efficiency in software development, agile practices are transforming methodologies for developing information systems. This paper discusses whether the two schools are in total contradiction and whether they can be in some way combined within the same project, showing the relation between the agile software development methodologies and the information systems development field.
