acronym For example By November 15 2008 Team Make A Difference will raise 1800 to be used for The Coalition to Save the Ducks to build a new duck habitat Different authors use different words to de ne a SMART goal For this course we use Speci cstated in clear concise terms This means that if you left the organization somewhere in the middle of the project another project manager would be able to read and understand what the goal is without confusion In our example money will be raised for Save the Ducks speci cally for the new duck habitat MeasurableThe results of the goal are veri able through some means This could include everything from complex evaluation forms numerical benchmarks or simple observation that yes the result occurred or no it did not In our example the total amount to be raised is 1800 If a nonmonetary goal is set teams can create client or enduser satisfaction surveys and state their goal in terms of a speci c degree of satisfaction that they will achieveie quotearning a client satisfaction score of 85 or higher and an participant satisfaction score of 70 or higher Action Oriented7Your project should be de ned in terms of some outcome that you can directly impact through your team s actions Develop measurable outcomes that you have direct control and autonomy over Your goal should enable team members to see what they should be doing to make your goal a reality RealisticYou goal should be something that you are likely to attain with hard work and proper planning You should set a challenging goal however it should be something that you have the skill and resources to accomplish within the given time constraints In our example the students have given themselves virtually the entire fall semester to reach their goal Their instructor agrees that this is consistent with their skill level and timeline TimeLimitedGoals must have a timeframe that they are completed within Speci c dates should be used to insure that all parties know what and agree on what to expect In our example the nal dollar amount will be raised by November 15 2008
