classification of process tasks. Types of processes 1st criteria should be to determine if the process has a single or a multiple stage .

Blocking - Occurs when the activities in a stage must stop because there is no place to deposit the item just completed. - Example: If there is no room for an employee to place a unit of work down, the employee will hold on to it not able to continue working on the next unit. Starving - Occurs when the activities in a stage must stop because there is no work. - Example: If an employee is waiting at a work station and no work is coming to the employee to process, the employee will remain idle until the next unit of work comes. Imagine we have a lack of raw material. Bottleneck - Occurs when the limited capacity of a process causes work to pile up or become unevenly distributed in the flow of a process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
