“In May 2019 Australian graphic design tool website Canva suffered an attack that exposed
email addresses, usernames, names, cities of residence, and salted and hashed with bcrypt 
passwords (for users not using social logins — around 61 million) of 137 million users. 
Canva says the hackers managed to view, but not steal, files with partial credit card and 
payment data. (Sourced from IT Security agency)

Referring to the case given, list and explain 2 steps that can help prevent data breach like this.

“…Many different departments within an organization now require access to the same data.
With conventional file processing, data are often duplicated in multiple files. Often
data are stored in different formats in each of the files in which they are stored. On
occasion, data which are stored in multiple files do not agree and time has to be
expended to resolve these differences. (Sourced from an Academic journal)

List and illustrate 2 benefits of a suitable database system to support a business like this.

With the arrival of the Internet, other mobile companies started
understanding how data, not voice, was the future of communication. Nokia
didn’t grasp the concept of software and kept focusing on hardware because the
management feared to alienate current users if they changed too much.”

List and briefly explain 2 factors that might have been overlooked by the business(es), referred to in the case.

Laura Moore has recently left her job as a Graphic Designer to open her own Company; a Graphic Design Agency dedicated to the creation and design of apps for mobile devices. Laura has decided to be self-employed.

To do so, she will have her business premises, which belongs to her father, in downtown Barcelona and she will have to hire:

• A visual designer
• A developer
• An administrative assistant

1. To hire the administrative assistant, Marta has decided to offer an indefinite contract. She is her first employee that Marta will hire and she has a recognized degree of disability of 37%. Explain to Marta what bonuses and reductions could be applied in the hiring of the administrative and what type of contract should she carry out, exposing its main characteristics. You must prepare the work contract of the Administrative Assistant according to the appropriate official model.

Once the contract has been drafted and completed according to Spanish regulations, you must specify in detail the differences it would have had it been made according to the regulations of the United Kingdom.

2. Knowing the salaries agreed upon with each of the two workers, prepare the payroll for each of them. Make sure you detail the steps you have taken and the financial nature of each of the items involved:

a. Administrative Assistant. Three months seniority. She has an indefinite work contract, base salary: € 1,500. Collective bargaining: € 50.

She has two extraordinary six-month accrual pays and receives them on 06/30 and 12/31 of each year for an amount equal to the base salary. She has a disability of 37% and is single without children. She has made two overtime hours that month at a rate of € 15/h.

b. Visual designer. 2 months seniority. He has a temporary contract.

Base salary: € 1,950. Collective bargaining: € 100. Productivity: € 6 / day. He has two extraordinary six-month accrual payments and receives them apportioned each month. He is married and has a 9-year-old son (his spouse receives an income of over € 1,500/year).

Once you have developed all the steps to follow in each case and the amount of the items, design and present the official payroll of the administrative assistant.

Question 3. Scheduling

ArtWork is a graphic design company. All jobs it receives must go through sketching (Process X) and then colouring (Process Y) in sequence. Each of the processes is operated by a dedicated designer.

1. The above 10 jobs have just arrived. Use Johnson’s rule to determine the optimal sequence to schedule the jobs. If there is more than one optimal sequence, show them all.

E

2. Draw a Gantt chart for your schedule. If there is more than one optimal sequence, show anyone of them.

3. Calculate the average flow time.

4. If you are allowed to split the last job in the sequence (pay attention, not necessarily the
   1. last job in the table) into two equal halves. For example, a job spends 6 hours in X and 4 hours in Y can be split into two jobs of 3 hours in X and 2 hours in Y. Without changing the sequence, do you think this arrangement is quicker? Why or why not?
5. The company has received four special jobs. These jobs have to go through sketching (Process X), colouring (Process Y) and then printing and coating (Process Z) in sequence. Each of the processes is operated by a dedicated designer. What is the optimal sequence to schedule the jobs? Show your steps. [hint: self-study is required]

On December 31 of last year, Lauren burst into the family living room and announced that she and Connor (her college boyfriend) were going to be married. After recovering

from the shock, her mother hugged her and asked, “When?” The following conversation resulted:

Lauren: January 21.

Mom: What?

Dad: The Now Wedding will be the social hit of the year. Wait a minute. Why so soon?

Lauren: Because on January 30 Connor, who is in the National Guard, will be shipping out overseas. We want a week for a honeymoon.

Mom: But Honey, we can't possibly finish all the things that need to be done by then. Remember all the details that were involved in your sister's wedding?

Even if we start tomorrow, it takes a day to reserve the church and reception hall, and they need at least 14 days' notice. That has to be done before we can start decorating, which takes 3 days. An extra $200 on Sunday would probably cut that 14 day notice to 7 days, though.

Dad: Oh, boy!

Lauren: I want Jane Summers to be my maid of honor.

Dad: But she's in the Peace Corps in Guatemala, isn't she? It would take her 10

days to get ready and drive up here.

Lauren: But we could fly her up in 2 days and it would only cost $1,000.

Dad: Oh, boy!

Mom: And catering! It takes 2 days to choose the cake and decorations, and Jack's Catering wants at least 5 days' notice. Besides, we'd have to have those things before we could start decorating.

Lauren: Can I wear your wedding dress, Mom?

Mom: Well, we'd have to replace some lace, but you could wear it, yes. We could order the lace from New York when we order the material for the bridesmaids' dresses. It takes 8 days to order and receive the material. The pattern needs to be chosen first, and that would take 3 days.

Dad: We could get the material here in 5 days if we paid an extra $20 to airfreight it. Oh, boy!

Lauren: I want Mrs. Jacks to work on the dresses.

Mom: But she charges $48 a day.

Dad: Oh, boy!

Mom: If we did all the sewing we could finish the dresses in 11 days. If Mrs. Jacks helped we could cut that down to 6 days at a cost of $48 for each day less than 11 days. She is very good too.

Lauren: I don't want anyone but her.

Mom: It would take another 2 days to do the final fitting and 2 more days to clean and press the dresses. They would have to be ready by rehearsal night. We must have rehearsal the night before the wedding.

Dad: Everything should be ready rehearsal night.

Mom: We've forgotten something. The invitations!

Dad: We should order the invitations from Bob's Printing Shop, and that usually takes 7 days. I'll bet he would do it in 6 days if we slipped him an extra $20!

Mom: It would take us 2 days to choose the invitation style before we could order them and we want the envelopes printed with our return address.

Lauren: Oh! That will be elegant.

Mom: The invitations should go out at least 10 days before the wedding. If we let them go any later, some of the relatives would get theirs too late to come and that would make them mad. I'll bet that if we didn't get them out until 8 days before the wedding, Aunt Ethel couldn't make it and she would reduce her wedding gift by $200.

Dad: Oh, boy!!

Mom: We'll have to take them to the Post Office to mail them and that takes a day. Addressing would take 3 days unless we hired some part-time girls and we can't start until the printer is finished. If we hired the girls we could probably save 2 days by spending $40 for each day saved.

Lauren: We need to get gifts for the bridesmaids. I could spend a day and do that.

Mom: Before we can even start to write out those invitations we need a guest list. Heavens, that will take 4 days to get in order and only I can understand our address file.

Lauren: Oh, Mom, I'm so excited. We can start each of the relatives on a different job.

Mom: Honey, I don't see how we can do it. Why, I've got to choose the invitations and patterns and reserve the church and . . .

Dad: Why don't you just take $3,000 and elope. Your sister's wedding cost me $2,400 and she didn't have to fly people up from Guatemala, hire extra girls and Mrs. Jacks, use airfreight, or anything like that.

Considering the list of items Lauren and Mom plan for the wedding, identify a contingency plan for three key items essential to the wedding. The list may not include the three original items you suggested alternates for, but it may include the alternates since you may assume that Lauren loved your suggestions. Why are these items essential to the wedding and therefore in need of a contingency plan?
