question 5

Multiple Choice

Mya is a programmer on the new inventory tracking system.She looks in the development library for a module that she needs to modify and changes a couple of lines in that module.BUT … at the same time Steve was also working on that module - getting it from the library before Mya did - and putting it back in the library after Mya made her changes and saved it.One common solution to this problem might be:

• A)To hold weekly meetings so Mya and Steve could discuss this
• B)To have all developers (including Mya and Steve)e-mail all other developers as they make changes to a module
• C)Have a program log / check-out system which would show that the module was already checked out (in this case to Steve)and that modifications can not be made until he checks it back in
• D)Have all developers call the Project Manager with any and all changes
• E)Have a 'white board' in the development area, where a programmer can write down the modules he/she is working on - and ask all developers to check the white board before making changes
