Subject: Performance Review and Reference Letter for John Addo
TO WHOM IT MAY CONCERN:
John Addo participated in the X-Culture Project in 2016.
X-Culture is a large-scale international experiential learning project that involves over 4,000 MBA and
business students from over 120 universities from 40 countries on six continents every semester. Over
30,000 students have participated in the project since its inception in 2010.
The students are placed in global virtual teams of about six, each student coming from a different
country. Working with people from around the globe and dealing with cultural differences, time-zone
dispersion, and global communication challenges, the teams complete a consulting project for a multi-
national company.
Before the project started, the students received training on online collaboration tools, international
team dynamics, cross-cultural communication and conflict resolution, and more. During the semester,
the students have had multiple live webinars with the CEOs and owners of the partner companies. A
number of students have also had opportunities to present their work to and received feedback from the
top managers of their client companies.
We rigorously measure and compare performance of the students and in the end rate the students on
over a dozen performance indicators, including peer evaluations, report quality, timeliness, creativity
and more. This provides an excellent work sample as performance in X-Culture is probably a good
predictor of performance in jobs requiring teamwork, cross-cultural interactions, and analytical and
research skills.

2. Our records of John Addo’s performance over the several months of X-Culture are provided below:
Diligence and ability to meet deadlines: Exceptionally high.
Peer-evaluated performance:
(1=very good, 2=bad, 3=acceptable, 4=good, 5=excellent)
Effort (project average: 3.9): 4.75
Creativity (project average: 3.7): 4.5
Leadership skills (project average: 3.4): 4
Collegiality and positive attitude (project average: 4.2): 5
Overall peer evaluations (project average: 3.7): 4.5625
The team has shared with us that of all work completed by the team, the percent of work completed by
John was 20 (project average: 18.5%).
Compared to the other 4,000+ participants this semester, John Addo’s individual performance was
better than that of 79.5% of the other project participants, or it was in Top 20.5%.
Expert-evaluated ability to:
(1=very bad, 2=bad, 3=acceptable, 4=not bad, 5=good, 6=very good, 7=excellent)
Solve international business problems and develop a business consulting project (project
average: 5.2): 5.13636363636364.
Creativity and ability to produce novel unconventional solutions (project average: 4.9): 5.2
Writing skills, ability to clearly present arguments and write properly formatted business report
(project average: 5.2): 5.2
Compared to other 784 global virtual teams that took part in the X-Culture competition this semester,
John Addo’s team’s report was better than 57.1% of other submissions, or in other words, the business
report was in Top 42.9%.
Recommendation:
Based on my thorough review and comparison of records for all the teams and students who took part
in X-Culture this semester, John Addo’s performance in the project over these several months, and in
comparison to other participants and teams, I can confidently recommend this person for a job that
requires work in teams, including cross-cultural virtual teams.
Also, I can confidently for jobs that require strong analytical, research, and writing skills, such as
business consulting projects.
Provided that John Addo has learned a lot during the X-Culture Project, I predict that John’s
performance will be better the next time.

3. If past performance is a predictor of future performance, I expect that John Addo will will do
exceptionally well on team-based international business consulting projects in the future.
Most sincerely,
