Problem Definition

As I explained in my blog of last week, the IT department is in its structuring process and in this blog I will discuss the evaluation process of the operating system, which is a software that manages computer hardware and software resources and provides common services for computer program, that we are going to use in the department that helps that staff to do their operation and administration in a secure and proficient manner.

Development of Feasible Alternatives
There are four feasible alternatives for the operating systems:
  1. Windows
  2. Mac OS
  3. Linux



Development of the Outcome for Alternative
The following attributes are considered to check which alternative is more suitable for this problem
  • Security
  • Compatibility
  • Technical support
  • Price
  • Reliability
  • Viruses
  • Processing Speed


Table 1 lists the comparison date for the three alternatives.
Table 1. Data Alternative

 Analysis and Comparison of the Alternative.
Using the compensatory approach, which consists of two models: Non-Dimensional Scaling and Additive Weighting Technique, the following results are calculated.

1.       Non-Dimensional Scaling
The below table shows the dimensionless values with a range from 0 to 1. Turning each attribute into a Base of 1 or dimensionless value, the scoring 1 means the highest/optimum value of attribute (preference decision). On the other hand, the scoring 0 means the minimum value (avoided decision).
 Table 2. Dimensionless Scoring model
Table 3. Dimensionless Relative Weighting

Using the quantitative comparison for each attribute in table 2, the total score is calculated to represent the rank of an alternative (table 3). Using the non-dimensional scaling, Mac operating system got the highest rank with a total score 3.50.

2.       Additive Weighting Technique
Table 4 below, shows the calculation using the additive weighting technique, where ranking the considered attributes by giving higher rank to the preferred attribute. The totals show that using Windows operating system ranked the highest value as the best option.
Table 4. Additive Weighting Score

Selection of the Preferred Alternative.

According to table 4 results, the best alternative is Windows operating system


 Performance Monitoring and the Post Evaluation of Result.
Each operating system has pros and cons and no operating system is better than other, the choice is up to you. Since the selection method shows that Windows is the preferred alternative for the IT department, we will start our operation using this option. In addition, in the future there might be a need for another OS depending on the coming requirements and needs.

During the current stage, every individual must submit a weekly blog related to a real work issue faced in the organization to determine the causes and the solutions. In  first blog Dr. Paul has requested  to measure the team development and behavior using   Tuckman’s Model. To insure the success of every project the  members must  understand the goals and the roles of each one to collaborate to achieve their goals. Further the team leader must understand his team behavior to know the most optimum leadership style must be adopted while managing the project.  2-      Identify the Feasible Alternative Tuckman m...

W1__Hamda__Tuckman Analysis Assignment__ 1-        Problem Definition After completion the first stage in PMP course which was conducted in Muscat from 29 th of October 2017 to 2 nd of November 2017 which was Face to Face stage, and following the formation of the OPWP-PMP team during this stage, the team is starting the second stage in this program which is the Distance Learning. Weekly Blog is one of the tasks in this stage. The first topic of the first weekly blog is suggested by Dr.Paul which is using Tuckman’s Model to know in which phase of this model the team is operated in and which style of leadership should be adopted in order to develop the team to achieve its goals. 2-        Identify the Feasible Alternative The Forming, Storming, Norming, and Performing model of group development was first proposed by Bruce Tuckman in 1965 who maintained that these phases are all necessary in order to develop...

Problem Definition Bruce Tuckman model used to identify the team status and the development phase of the project team. As the team go through these phases, different strategies should be implemented by the team leader and managers. This assessment will provide enough information for the team leader and even for the team members that would give a good understand the team performance.   Identify the Feasible Alternative There were 4 stages model of "forming, storming, norming, and performing" introduced by Bruce Tuckman in 1965. However, a fifth stage was added “adjourning” which describe the phase that the team go through after the achievement of project tasks and completion of the project. Figure 1 , development stages [2] In each phase, the leadership style should be in alignment with that specific phase which enhance the development of the team and improve the performance of the team as well. There are different styles that could be used by the team le...
