Ultimately, you should always have as complete a set of information as possible prior to making any decision regarding doing business; however, there will be times when it is impossible to obtain all of the necessary information. If you have enough reasonably accurate data to minimize risk and be in a good position to choose wisely, that is paramount. For business owners, knowing about the market, cost, revenue, competitors, and the potential of difficulty with any decision they choose to pursue should be a priority. Having good data can help you avoid making poor decisions, as well as help improve your planning. Generally speaking, if you wait for all of the data before moving forward, you could seriously delay your progress. Most successful operations utilize the available information, experience and/or and careful analysis to reach a decision then are willing to make changes according to new data that may arise within the process.
