- Differences made to the world
New way to play the game.
New way to watch the movie, better experience, since when you are wearing the headset, you cannot see the real world.
- Impact
It has caught the eyes of the person, like venture capital, global experienced repeated entrepreneurs and encourage them to start up new businesses.
Besides, in game industry, virtual reality has become one of the most popular way to play the games.
In low-end markets, it also gives a more experience when you are watching movies with a VR headset.
However, it also leads to some possible negative effects.
Since when the person is using the VR headset, he/ she totally immerses in the virtual world. It might further enlarge the influence caused by the electronic product. That is, reducing the communication among people in the real world.
Besides, it might lead to more teenagers becoming network addiction since VR technology can provide more really immersive experience.
Question 3.
NZ police case study. Discuss what went wrong in this case study how would you have done things differently? Does Whittakar (1999), “What went wrong? Unsuccessful information technology projects” provide any insights into this particular disaster? (10 marks)
Answer:
Case review and comment:
There are several main problems:
The NZ police case study is a long period up to 7 years, so the technologies are used in the project might be out of date. Actually, at that time, the new operating system, Microsoft NT was first introduced, and the manger did not refresh the system in time.
During the development of project, the new user requirements showed up and the IBM also pulled out in the half way.
Besides, the project cancelled with only 1/3 project was completed, and over time which is 12 months behind and over budget up to 4 times more than the estimated cost.
I will focus on several parts below according to these problems.
Since this is a long period project, I will pay more attention to new technology. This is because when the project takes a very long time, the initial technology might be out of data, we should keep updating the technology in order to ensure the technology will not hinder the development of the project.
Based on the case, the project is over budget and over time. If I do the project, I would combine the WBS, expert advices and other estimate tools together in order to make the estimated schedule and cost more reliable. Besides, I will use the network diagram to calculate and the planned time with slack is not empty. In this way, I can have extra time to deal with some accidents, like behind the schedule. Furthermore, once some risks happen, we will revise the budget, time in time and negotiate with the customers.
Traditional management approach, such as waterfall, is not compatible with project with high uncertainty, so I will use the agile to manage the project. In this way, we can maximum deal with uncertainties, such as new user requirements, new features, market changing and so on. Besides, I will encourage the business people to communicate with developers, testers daily, so the new features and requirements can be transferred to the project better.
In addition, I will focus on the change management which relates to people side of change. As many studies show, the human resistance is the biggest factor leading to the failure, and hence we want to minimize the influence from this factor by using change management. Besides, when implementing the change management successfully, it also can improve the efficiency and so on.
The article helps a lot on the project plan. It defined and analyzed three major reasons that lead to a failed IT project according to a case: (1) Poor project planning; (2) A weak business case; (3) Lack of top management involvement and support. In this cases, I think the poor project planning is one of the most important reasons leading to the over budget and behind schedule.
Question 4.
You have been asked by your manager at work to develop a proposal for a new IT project idea. Discuss the key elements that he will require for submission to the investment committee to ensure funding is made available, i.e. what resources, technology, timing, budgets, etc. will be required, does “IT projects: a basis for success” from Wateridge (1995) help in this exercise? (10 marks)
Answer:
- Determine work breakdown structure
Define the total scope of the project, like project goals and also mentioned in the reading, deliverables, tasks, costs and deadlines. Besides, when building the wbs structure, we should try to make it as detailed as possible. According to the reading, we should focus on the success criteria and have a thorough understanding on it. The success criteria need to be defined clearly, agreed by all parties at the beginning of project.
- Estimate amount of effort required
According to following 5 steps, estimating the efforts are needed.
size: analyze the size of the project.
Effort: like, the person hours, days, months
Resources: like, how many engineers or programmers are involved
Duration: effort/ resource
Cost: for example, 20 persons, at 70 Australian dollars per hour, = 1400.
- Determine dependencies between activities
In order to translate a work breakdown structure into a work schedule we need to determine which activities must be completed before others may begin. Such activities are called predecessors. It is important to identify predecessors completely and accurately, because they determine the duration and flexibility of the whole project. The project manager must have a thorough understanding of the project, such as the nature of each activity.
- Devise project schedule
Based on above three steps, we can devise the schedule of the project. Besides, based on some criteria given in the reading, we should ensure the schedule stratifying the needs of both users and project team.
