What do poker, Greek oracles, an Italian mathematician from the Middle Ages, and the path of hurricanes have in common? Given the title of this presentation, chances are it has something to do with estimation, and you'll have to attend this session to get the full connection. Kent McDonald explores the challenges and realities of trying to estimate software-related knowledge work-analysis, testing, development, and the entire project effort. A major challenge is that there are no guaranteed ways to arrive at perfectly accurate estimates, which not surprisingly is why they are called estimates. Kent introduces and gives you a chance to practice quick and practical estimating techniques that will work in different situations-guesstimating, break it down and add it up, and planning poker.

In this lightning talk from STAREAST 2011, Dale Emery takes a look at some common issues we encounter when estimating and explains why they aren't actually estimating problems.

The team, running Scrum by-the-book for three months, was continually failing to meet its delivery dates. As a result, trust between the business managers and the team degraded almost to a point-of-no-return. The team, which held bi-weekly retrospectives, could not pinpoint the problems causing its inability to ship. Mitch Lacey was asked to assist the team in finding the root cause of its problems. He analyzed multiple aspects of the project-from individual work items to planning meetings. While multiple issues were identified, one thing stood out above all others--the estimation process used had caused the team to miss its deadlines. Mitch discusses the estimation problems the team was having, how they were discovered and fixed, and the resulting improvement in financial and customer satisfaction.

Gone are the religious wars of plan-driven vs. agile software development methodologies and practices. Recent surveys indicate agile practices are being adopted in many software development organizations, with others seriously contemplating making the switch. The question from most organizations now has turned from plan-driven vs. agile to which agile practices they should use in their development process to most improve their business results. The experiences of other organizations that have adopted agile practices help answer this question. Based on her empirical studies of Extreme Programming teams and other agile practices, Laurie Williams shares her views on which agile methods have been most beneficial to industrial teams practicing agile development. Armed with real data, you can implement changes with more confidence that they will add value in your organization.
