Problem $2$:

$$Buy or build$$ is simply the decision.

Project A: Outside building.

$$ The cost of the decision if you $$buy$$ the work outside of your company is $$175,000.$

$$ Based on your probability of completion by a given date, you apply the $85$ percent certainty to the $$strong$$ finish for the Buy branch of the tree. Because your $85$ percent certain, you$$re also $15$ percent uncertain; this value is assigned to the $$weak$$ value on the Buy branch.

Project B: In$-$house build

$$ If you build the software in$-$house, the cost is $$165,000.$

$$ In$-$house teams state they can complete the work on time with $75$ percent certainty.

The best decision is based solely on the largest value of all possible decisions. Explain your decision.
