This document summarizes a study of CEO succession events among the largest 100 U.S. corporations between 2005-2015. The study analyzed executives who were passed over for the CEO role ("succession losers") and their subsequent careers. It found that 74% of passed over executives left their companies, with 30% eventually becoming CEOs elsewhere. However, companies led by succession losers saw average stock price declines of 13% over 3 years, compared to gains for companies whose CEO selections remained unchanged. The findings suggest that boards generally identify the most qualified CEO candidates, though differences between internal and external hires complicate comparisons.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Introduction
A usability test was carried out on the www.cozi.com web application at Kingston University. A usability test is
intended to determine the extent an interface (such as a website) facilitates a user’s ability to complete routine tasks
and how it would make his life easier. Usability testing has many benefits, including that it improves the ease of use of
a website and enables the designers and developers to learn about things that will improve its performance.
In this project, an onsite usability test was conducted using the live version of www.cozi.com.
Full Product Description
Cozi.com is a free online organizer and planner web app that helps families manage their schedules, shopping lists,
household chores and to-do lists – all in one place.
The target audience is primarily families. Other users are groups of friends. Types of work supported by the app are
shopping lists and to do lists, appointments and activities, chores, and meals.
Test Objectives/Aims
The objective of the test is whether the app is user-friendly and whether it serves its purpose.
Examples
● Whether or not the site easily and quickly allows the user to create, edit and view his or her schedule
● User’s overall experience with the website
Executive Summary
The www.cozi.com test users took part in the usability test at the Penrhyn Road campus at Kingston University in
London, England on 6th December 2012. The purpose of the test was to assess the usability of the web interface
design, and whether routine tasks could be easily achieved.
6 users participated in the test. Typically, a larger number of participants are involved in a usability test to ensure more
reliable results. However, limitations of the project were the number of participants available. Each individual test
lasted approximately 30-40 minutes.
Analysing from the questionnaire, all participants found the Cozi.com website to be clear, straightforward and 67%
found the website easy to use. The test identified some problems, including: confusion with the terminology and lack
of feedback.

Five participants were students and one was a full-time worker. Six participants were scheduled to take the test over
two testing days (6 and 7 December 2012). Six out of six participants completed the test. Three participants were male
and three were female. The age range was 22-26 with a mean age of 23.8 years old.
All participants were frequent computer users with a good working knowledge of Microsoft Windows. None had used
the product befoe. Two participants have had experience in online calendar applications and the rest are very familiar
with mobile planners.

Sessions
Participants were recruited from the university. Each individual session lasted approximately 30-40 minutes. During
the session, the test was explained and the participants were asked to fill out a questionnaire about their background.
The tests were carried out without any interruptions.
Context of Product Use in the Test
Tasks
Intended context of use: Participants were interviewed with a pre-test questionnaire about their initial impression of
the website and their experience of using similar websites or calendar applications.
Context used for the test: Test participants attempted completion of the following tasks (see Appendix for more
details):
1) Creating Events
The participant must create two events on the calendar on the given dates and times
2) Family Member
The participant must add a family member and create an appointment for him on the given date and time
3) Calendar Colour Code
The participant must change the colour of the calendar colour code of the family member
4) Sharing Calendar
The participant must share their calendar with a friend using the specified email address
5) Repeated Events
The participant must create a repeated event that lasts for two months and set a reminder
6) To-Do List
The participant must go to the specified to-do list and strike off the tasks given in the test
7) Shopping List
The participant must plan a meal on the given date, find the recipe from the given selections and add it to the
Family Favourites. Then the ingredients must be added to the shopping list, which should be named ‘Cooking’.
Test Facility
Intended context of use: home.
Context used for the test: Two participants carried out the test in the lecture hall at Kingston University, Penrhyn Road
campus. The remaining participants carried out the test in their homes. Participants worked without any interruptions,
and were recorded using computer software. I sat beside them out of screen-sight.
Participant’s Computing Environment
Intended context of use: www.cozi.com web app is intended for use on any browser. The web version is not intended
for use on Smart phones and external devices.
Context used for the test: All the participants were asked to use my own laptop which has
• Windows 7 premium operating system
• Pentium T4300 , 4gb RAM
• Resolution: 1366 x 748
• Safari Browser
• ‘Camtasia’ screen recording software
Materials – Test Administrator Tools

Tasks were recorded and timed using Camtasia (trial version). Sessions were filmed (a combined picture of the screen
and a view of the participant). At the end of the sessions, participants completed a post-test questionnaire (see
Appendix for details).
Manual input devices: Key board & Mouse
Procedure
Before the test, participants were informed that we would be investigating the usability of Cozi.com during the
session, to find out whether it was easy to use and served its purpose, and how long tasks took. They were told that it
was not a test of their abilities, but a test of the website itself. Participants were informed that they would be recorded
during the session. They were asked to sign a consent form. Participants were asked about themselves before the test
tasks: occupation, their experience with online calendars, computer experience.
Participants were given instructions before the test, and also told to think aloud during the test. They were asked about
their initial impression of the website.
After the last task, participants were asked to complete a post-test questionnaire which asked about their overall
impression and experience using the website.
I asked the participants if they encountered any difficulties using the website and whether there is anything that they
felt could be improved.
Before beginning the test with a new participant, I have cleared all the data(events and fields) which was created by
the previous participant.
Expected Results
It is expected that Cozi.com is user-friendly, bug-free and intuitive to use – it is a live product.
Results
Most of the tasks were successfully completed by all the participants. All the participants have spent more time to
accomplish the tasks 2, 4 and 7. Although adding a family member/s is the main purpose of the application, users
found hard time to add a family member to their account. The mean time taken by all the participants to complete all
the tasks is 25min and 40sec.
Performance results:

Task 2:

7. Sarat Koneti
Findings in task 1:
• Six out of six participants did not know instantly how to add an appointment to the calendar. All the
participants wasted at least one click before double clicking. It was not clear that they had to double click on a
date to make an appointment.
• However, All participants(100%) managed to complete the task eventually. One participant partially failed to
complete the task in the expected direction.
• When signing in, if you get either the username or password wrong, it does not inform you which is wrong.
So the user has to type in both username and password again, whereas if it just said, e.g. password was wrong,
they would only have to type in the password. One participant did not like this.
Two ways of adding appointments to the calendar
Recommendations for task 1:
• There should be a tooltip or it should be intuitive to double click to add an appointment to the calendar.
(‘tooltip’ should be disappeared in 20sec from the time page loads or when clicks to close)
• Suggestions to improve include better design to make the user automatically think to double click on the date
cell, or there should be an icon in the cell ( add should appear when user mouse on the date cell, if events
already exists edit button should appear.
‘Tooltip’ indicate the user to double click ‘add & edit’ icon on a date cell

Findings in task 2:
• All participants took a long time to add a family member to the account. One participant had to use the Help
screen.
• 6 out of six participants (100%) clicked on the family photo if they could find more information. But right
now user will only be able upload his/her photo in that section.
• Generally the participants did not understand the terminology needed to add a family member, i.e. it was not
clear they had to go to “General information about household”.
• Though they are at the right screen, 2 out of six participants did not notice that it was the right place to add a
family member.
• 3 participants felt they could find the family information on the home page.
Here are two ways to add a family member

9. Sarat Koneti
Recommendations for task 2:
• There should be more intuitive ways to add a family member. For example, there could be an item in the
menu that says “My Family”. This would be more obvious and direct solution.
• Other alternatives could be by clicking on the “family photo” the user would be taken to the whole family’s
information. This would be a good solution, as my test shows 67% of participants expected this anyway.
• The terminology “General information about household” could be clearer to the user, i.e. it could be “My
Family”. Two out of six participants actually arrived at this screen but clicked away because it was not
obvious it was the correct place to add a family member.
• Another solution could be to have the family information shown on the homepage, for example, a “Welcome”
message and then a “Family information” section.
• This task proved to be more of the more difficult. However, it could be easily resolved.
Recommended changes in navigation to add a family member

Findings in task 3:
• 5 participants were managed to complete this task easily.
• One participant thought it is not possible to change the colour code of the family member but finally he
managed to complete the task after seeking assistance. The reason for his confusion is participant could not
see the family members calendar colour codes in month view. So he thought that, it does not exist.
• 4 out of six participants able to complete this task in less than 2min.
• 2 participants clicked directly on the small circle icon which was used to represent the family member colour
code to change its colour.
• 3 participants expected to change colour code from the same page where they have added a family member.
• One participant expected that changing the calendar colour code of the family member, will affect the entire
colour theme of the calendar e.g. date colours, appointment colours for that specific family member.
• One participant suggested that changing the calendar colour code of the family member should change the
appointments of that specific family member.
No colour code for family members in month view Colour code for family members in day view
Recommendations for task 3:
10
11. Sarat Koneti
• Although five participants completed the task easily, there were some unnecessary clicks (more than required
to achieve the task) by most of them.
• A suggestion is to have this colour change ability on the calendar itself. Also, as recommended by one the
participant’s, the colour change should be used to differentiate between different family member
appointments.
• For example, if Peter’s calendar colour is red and John’s is blue, when the user looks at the whole family’s
calendar, he would see all Peter’s appointments in red and John’s in blue. This change would be time-
consuming and require developer input.
• Currently, the only significance of the calendar colour change is superficial and not to improve usability.
• When the calendar colour is changed, only the heading bar on the calendar changes colour. To be more user-
friendly, I would recommend that the whole calendar colour is changed, as one participant expected.
• Considering all the suggestions, I recommend that instead keeping button name ‘show’ on the top, It could be
the family member name which is active. Also colour change for the appointments
Present menu for filtering appointments Recommended menu
Findings in task 4:
• Most of the participants found problems in sharing the calendar with his/her friend.
• All the participants did at least 2 mistakes to share the calendar.
• 3 out of six participants tried to share the calendar from the date cell on the calendar, which is wrong.
• Some participants felt the terminology used to share the calendar was misleading, “Send URL”- They were
not clear about the completion of the task.
• One participant was confused with the text area where they had to enter the email address.
• Most of the participants wanted an acknowledgement that the calendar had been shared.
• One participant wanted to see a history of people with who he had shared the calendar.

12. Sarat Koneti
Participant was not sure the she is doing right
Recommendations for task 4:
• This task was very unintuitive. Recommendations are to change the terminology, so instead of “Send URL” it
would say “Share Calendar”. Once the calendar had been shared, there would be an acknowledgement that it
had been shared. As suggested by one participant, it would also be better if the user could see a history of who
had been sent the calendar.
• There are currently two ways in which the calendar can be shared- directly from the calendar under ‘Set up’
and then ‘Share appointments’ or in the Settings menu and then ‘Calendar Settings – Send URL’. This is not
user-friendly – the terminology should be consistent. Both phrases are misleading. I would recommend “Share
calendar” for each one. This is easy to do.
• One participant’s suggestion was to see a history of people the calendar had been shared with, which I think is
a good idea. However, this would require further development and would be time-consuming.
My recommendation for sharing calendar design

Findings in task 5:
• All the participants completed this task with ease except the participant who fails to know that, double
clicking the date will allow him/her to add an event, chose different way to complete this task too. Four out of
six participants did not like the American date format.
Failed participant way to add repeated events General way of adding repeated events
Recommendations for task 5:
• Same recommendations as with task 1 – to double click an appointment should be more intuitive. Under
Settings, there should be a way to format your date and time depending on your country. This could be easily
resolved.
Findings in task 6:
• Six out of six participants completed this task with ease.
To-Do list
Recommendations for task 6:
13
14. Sarat Koneti
• The To-Do list functions well. An alternative idea could be to have a ‘Complete?’ button next to the item,
where the user can tick whether they have done it. However, because 100% of the test participants completed
this task very easily, this is not needed.
Findings in task 7:
All the participants took a long time to do this task. There are three parts to this task:
● Some participants chose the calendar page instead of Meals page.
● To add a recipe to the Family’s Favourites – all participants completed this task easily
● To add the list of ingredients needed to the shopping list and name it cooking – all the participants completed
this task easily
Exsiting Meals Interface(The right side ‘your recipe box’ is neglected by the most of the users)
Recommendations for task 7:
• I would recommend to reduce the number of steps needed to plan a meal from ‘Cozi Picks’. Instead of going
to different pages, all the information would be on one page arranged in columns so the user can easily drag
and drop from one column to the date.
• It is not intuitive to drag and drop how it is now, I would suggest using a tooltip on the mouse-over. Although
all participants completed the task successfully, the times were very long and could be reduced with further
thought and design.

Discussion
Most of the participants enjoyed using the software and found it acceptable to use. However all participants are
unlikely to use the website in the future. This is most likely because there are alternative options, such as mobile
calendars, Google calendar etc. However, my test results may not be truly representative because the participants were
not specifically the target audience of the website, i.e. not “busy families”. However, all participants were users of
online or mobile calendars so the context of the test was appropriate.
