" Authoritarian managers use power, often in the form of fear, to get people to do something their way. Leaders depend for the most part on influence rather than power, and influence derives from respect rather than fear. Respect, in turn, is based on qualities such as integrity, ability, fairness, truthfulness—in short, on character. Leaders are part of the team, and although they are given organizational authority, their real authority isn't delegated top-down but earned bottom-up. From the outside, a managed team and a led team can look the same, but from the inside they feel very different. "

" When applying agile practices at the portfolio level, similar benefits accrue: • Demonstrable results—Every quarter or so products, or at least deployable pieces of products, are developed, implemented, tested, and accepted. Short projects deliver chunks of functionality incrementally. • Customer feedback—Each quarter product managers review results and provide feedback, and executives can view progress in terms of working products. • Better portfolio planning—Portfolio planning is more realistic because it is based on deployed whole or partial products. • Flexibility—Portfolios can be steered toward changing business goals and higher-value projects because changes are easy to incorporate at the end of each quarter. Because projects produce working products, partial value is captured rather than being lost completely as usually happens with serial projects that are terminated early. • Productivity—There is a hidden productivity improvement with agile methods from the work not done. Through constant negotiation, small projects are both eliminated and pared down. "
