Out of the three listed objectives, achievable is the critical objective. This objective has to be based on a plethora of other sub-factors. The amount of time it will take, the number of employees a company has, do we have enough money in the budget to do so. The trivial solution is if we have everything then yes this project is achievable. In essence, the reality is not always what you want. You have to work with what you got. If you have to build the NASA space station and you only have 50 workers and maybe 2 suppliers the possibility of achieving the end product will be unsuccessful. If the timeline is 2 years when really it takes 8-10 years to build this station due to needing many suppliers and or different manufacturing processes to be done. The list goes on. The scope of the project is what will help a company to have an achievable end result as well.
