Read the case study below and answer the questions that follow. The Importance of the Planning Phase to Project Success. Traditional wisdom is that planning and analysis are very important and the more there is in a project, the more successful the project will be. Time spent on these activities will reduce risk and increase project success. On the other hand, inadequate analysis and planning will lead to a failed project. If poor planning has led to failed projects, then perhaps billions of dollars have been lost. But how much is too much? “Light weight” project management techniques such as agile are gaining popularity. Part of their ethos is that less initial planning is better and an evolutionary process is more efficient.
