A project segment consists of three tasks.$$ Task A is scheduled to begin at the start of Week $1$ and finish at the end of Week $3.$ Task B is scheduled to begin at the start of Week $1$ and finish at the end of Week $2.$ Task C is scheduled to begin at the start of Week $2$ and end at the end of Week $3.$ Budgeted cost for Task A is $$148,450,$ for Task B is $$121,000,$ and for Task C is $$93,900.$ A total of $$86,000$ is being carried for a contingency.$$ This project has a very high level of risk, supporting a risk factor of $35\%$ which equates to labor coverage of $$71,649.$ Coincidentally, labor costs are running approximately $15\%$ over budget due to project complexity.$$ At the end of week two, Task A is $50\%$ complete, Task B is $80\%$ complete, and Task C is $45\%$ complete.$$ Calculate project schedule performance index for tasks A$,$ B and C corresponding to end of week two.$$ Indicate project schedule status based on calculated SPI index.
