Planned value and actual cost matter in the monitoring and controlling phase because they can determine future actions that can be taken by the company. If the company is ahead of budget and ahead of time then they may be able to pursue a more advanced product and could spend more time in the design phase. Also, they can now allocate more resources to marketing so that they can branch to other potential buyers and from there gain more potential stakeholder and investors. By looking at where the team is in terms of the project and success rate, they can get a more accurate time table for the rest of the project. If the tea does not monitor it’s actual cost then they can fall over budget and be very tight on money or may have to fold the project if the funds run out and the project manager had no idea the funds were running low. By knowing the actual cost, you can develop a control scheme that can help reduce the risk of your project failing.
