- One of the qualifications that the team members should be looking includes understanding the business operation. There is a need to understand the business and how the organization works together to achieve the profits. The new members should understand the business processes that are common for many businesses and especially the ones that are commonly seen to be working for vitamin companies. Another qualification is communication skills which is an important component. This is because they will be required to talk to the system users as they get the requirements and understand the problems that the users have with the current system (Roth, Dennis, and Wixom 72). This is one of the best ways in which the problems will be understood. There is also the need to have technical qualifications like the understanding of the current technologies that are used in e-commerce. This will ensure that there is an understanding of the technologies that will be used in the e-commerce (Satzinger, Jackson, and Burd 228).
- It is more important to have the aptitude to pick software languages and packages quickly. This is because one may know many languages which are obsolete or irrelevant to the business problem. It is important to know which languages should work for which situation.
- It is important for the new person to know some business understanding because they will be solving a business problem. This knowledge will be required so that they will be able to understand the issue that is being solved. It is useless to know the languages that will be used to program and yet do not know about the business aspect and the solution that is required for the business (Laudon, and Laudon 228).
- No, there should be a blend of technologies and skills that is possessed by members working in the e-commerce project. This will help when the various skills will be required for developing a project (Laudon, and Laudon 29).
- One of the personality traits that will be required is good communication skills. Another personality trait that will be required is that someone should be a good decision maker. They should be able to make decisions quickly and the right ones for the business.

PERT diagram
Explanation of the critical path and the PERT diagram
- The critical path is the longest path to the finish. This is shown in the computation below
- 10-30-40-50-60-70-80 = 6+3+2+5+3+2=21
- 10-20-30-40-50-60-70 = 3+2+3+2+5+3+2=20
- 10-30-50-60-70-80 = 6+4+5+3+2 =20
- 10-20-30-50-60-70-80 = 3+2+4+5+3+2=19
In this case, the critical path would be 10-30-40-50-60-70-80 because it took the highest time to achieve. This is 21 weeks.
- This would help save the other tasks. This would be a big save for the project. This is because it would be beneficial to the other tasks that will come after the task. It has dependencies.

Problem IV
Section 1
- This is right because it is about testing the logic of the program. It will be right to skip this test if the same algorithm has been used as this will show the same results. If the algorithm is still intact, then it means that the program is still working fine and showing the same results (Chaffey, and White 28).
- This is right and should be done because the e-commerce will work with large amount and volumes of data in the e-commerce model. Testing it with large amount of data will; ensure that there is a better understanding of the e-commerce model. It will enable the system to work with large amounts of data without testing again when it has been under operation.
- It is not right to perform testing with live data if it is just for checking. The testing should be done using dummy data. Live data should be used for testing at the final stages and when it is assured that the system is working for the better of the system. Testing live data with systems which have not been tested before will affect the reputation of the company because some clients might log into the system and see a fault. They will have a bad reputation for the company (Lacity, and Hirschheim 82).
Section 2
- The system might damage the data that is to be used for evaluation. This will be hard to redo the analysis of the data in the future. It is important to have a working system because the data will be safe while it is being evaluated. There will be no issues with the data that will be evaluated using the system. It is important to understand the requirements of the data that is being evaluated sp hat there is no damage that will be caused in the system. The system could also give inaccurate results because the complaints of the users are that there are problems with the inputs and outputs of the system. This problem could be a recipe for wrong analysis because of the wrong input that has been input to the system. This will cause the new system to bring wrong results to the management and will cause the management to make wrong decisions on the various issues. This will cost the company many issues and problems. A system which has not been evaluated could also be a waste of time and resources if it is used. This is because there could be problems that will be involved with the use of the system and the problems will take time to be solved.
- The following issues and components should be evaluated:
- Are the inputs functioning well?
- Are the outputs working okay?
- Does the system connect with the database well?
- Does the system update the database well?
- Is there communication between the different modules?
- How fast/slow is the system when processing information?
- Are there some bugs in the systems that are obvious?
- Are there some security lapses within the system?
