13 The government is going to build a high-speed computer in Austin, Texas. Once the computer is designed

(D), we can select the exact site (S), the building contractor

(C), and the operating personnel (P). Once the site is

selected, we can begin erecting the building (B). We can start manufacturing the computer (COM) and preparing the operations manual (M) only after contractor is selected. We can begin training the computer operators (T) when the operating manual and personnel selection are completed.
When the computer and the building are both finished, the computer may be installed (I). Then the computer is considered operational. Draw a project network that could be used to determine when the project is operational.
