Dell, previously the world’s number one PC manufacturer, has seen its market share shrink because of rivals copying its value ch
stepladder [879]

Answer:

A) underscore the importance of continually assessing a firm's strategic position among changing market conditions.

Explanation:

Dell computers believed their leadership position would last forever and forgot the basic rule that it is very hard to reach the top, but it's even harder to stay there.

The market conditions changed since globalization made the world smaller, increasing the potential customers but also increasing competition. Dell wasn't able to revise their strategic position and adapt it to changing markets. A company's strategic position refers to how its strategy deals with changing:

  • environments,
  • competition,
  • resources,
  • stakeholders' expectations.

The same thing happened to General Motors, that once used to be the largest and most profitable car manufacturer in the world, and then went bankrupt. It is still under a lot of financial stress and is continuously losing market share in the US and around the world.

Non-preemptive Shortest Job First (SJF) scheduling policy is not optimal if:
ivann1987 [24]

Answer:

The answer is A

Explanation:

Basically, Shortest job first (SJF) is a scheduling policy that selects jobs on queue for execution  within a short execution time.

From the definition of SJF above, it means that there are a lot of process on queue and the (SJF) job is to receive processes on queue to execute within a short execution time.

Therefore, if all the jobs or process arrives at the SJF at the same time, the SJF will forfeit one of its major purpose which is scheduling of jobs.

That will therefore not make Non-preemptive Shortest Job First (SJF) not function at its optimal point.
