Q

An investment project requires an initial investment of $1M and will result in a profit of $10M in 8 years. The discount rate is 9%. What’s the NPV?

A

NPV = PV of profits - PV of Investment+costs

With discount rate of 9%, using “Rule of 69-72”, the investment will double in 8 years.

So the $10M profit 8 years from now is worth half today, or $5M.

So the NPV = 5M - 1M = 4M

Q

Challenges and Benefits of Creating a Diverse Workforce

A

Benefits:

Organizations do their best work when their teams reflect the constituencies they are serving, which in Google’s case, is the entire world. Diverse teams solve problems more effectively because they have insight from more unique perspectives and are less likely to make mistakes due to avoidable blind spots.

Google is competing for the world’s top talent, and this talent is wildly diverse. However, people from underrepresented backgrounds face unique challenges in the work place that often cause them to fail to meet their potential or make them not want to work in a particular organization. For many people, it’s important for to have friends, mentors, and colleagues at work who are similar to them for them to feel included and appreciated.

Challenges

Need to eliminate as much bias as possible in human capital systems, from hiring, to training, to pay, to promotion. It’s great that Google takes this so seriously:

–> The vast majority of Googler’s have done unconscious bias training

–> That Google has eliminated statistically significant pay gaps by gender or race.

–> Hiring decisions are made on rubrics and by a committee to reduce bias

–> 20% time for diversity efforts: Diversity Core is a formal program in which Google employees contribute one-fifth of their time to initiatives aimed at attracting more women and minorities and creating a more welcoming culture for them — both at Google and in the tech industry.

It’s challenging to create an inclusive work environment that will make people from underrepresented backgrounds want to join and stay on the team. People have deeply ingrained conscious and unconscious biases that affect the way they interact with their colleagues, often creating a toxic environment.

Disagreement within our society about how much of a role identity-based bias plays in outcomes, and whether or not as a society we should even strive for equity in outcomes. This makes it hard for some companies to focus on diversity because their shareholders are not uniform in their beliefs and demand immediate returns, and it’s not always easy to quantify the profit benefit in the short term of promoting diversity in your workplace. Especially, since research shows that in certain circumstances, diverse teams are less productive.

–> My experience:

I’ve spent my entire career in some of the more progressive organizations in the country. I’ve only worked in schools that serve low-income brown and black children and most of my managers have been people of color. In each organization, we did dozens of hours of diversity and inclusion work each year, which I fully supported and contributed to. As a result, I’ve been a bit shocked at business school to realize what the rest of the world is like - I have a lot of classmates who think that D&I work is a waste of time and is a threat to them, people have walked out of our D&I workshops midway, visibly annoyed. It’s really awoken me to the challenge that we face across corporate America. As a result, I’ve been trying to contribute to making Columbia a more inclusive space: 1. I took on a leadership role in a men’s ally group for women in business, and I joined the campus’ diversity and inclusion club to try. We have a ton of work to do.

Q

Percentage change of revenue when adjusting price, quantity

A

% change = price change 1 + price change 2 + (price change 1 * price change 2) example: A company has $300m in revenue which grows by 20% and then shrinks by 10%. What’s the net change in revenue? 1 + 20% - 10% + (-10%*20%) –> 120% - 10% + -2% = 108%, so 8% change. example: How much will revenue change if a company increases prices by 20% which leads to a 20% decrease in sales? –> 1 + 20% + -20% + -4% = 96% –> change of -4%

Q

Price elasticity and inelasticity

A

If price elasticity is greater than 1, we can decrease prices to increase revenue. If price elasticity is less than 1, lowering prices will lower revenue. If a good is inelastic, that means that quantity bought doesn’t really change with changes in price. I.e. raising a $200 drug to 202 (2%) increase will cause sales to drop by less than 1%.

Q

Fixing a process that’s not working, problem solving

A

One of the top complaints from our staff our first two years is that they were constantly distracted by the quantity and variety of communications from their colleagues and managers, and that they didn’t know where to find any of the information they needed.

Similarly, their managers were complaining that teachers weren’t reading their emails or completing their tasks.

I suggested to my principal that I spend a lot of time over the summer and in the early fall designing a new communication system and associated staff-wide expectations to address the issue.

First gathered data from a wide variety of staff members across multiple teams - what were their biggest sources of frustration with our current communication and data storage, what would they want to be true about an improved system?

Then I analyzed all the interviews and survey results and noticed there were three top priorities:

    1. Teachers needed to be able to focus on their most critical work* without constantly being interrupted by text messages from their colleagues, or with fear that they would miss out on critical information if they weren’t constantly checking their email. At the same time, leaders needed their direct reports to read updates fairly frequently as were building the school day to day and plans were constantly changing.
    1. Teachers felt like they were receiving deliverables from all angles at all times of the day.* There wasn’t a single list of tasks they had to complete for the various departments that were making requests of them, and people were requesting time-intensive action at the last minute due to poor planning. People were missing deliverables right and left.
    1. Teachers needed a consistent place to find the various documents and trackers their teams and managers were creating and using* - they seemed to have a new tracker to fill out every couple of days and couldn’t keep track of them in their email.

I then created a high level vision of how communication would be different for the next year - I didn’t choose specific tools or get into the details. The big pillars were:

    1. Clear rules about when to use email versus when to use a text-message like communication tool, based upon how urgently the recipient would have to read the message.
    1. 95% of tasks teachers had to complete would be put in a single document that was collaboratively created and then carefully edited by Thursday of each week, for the following week. This was to promote better future-planning and to decrease the number of missed tasks.
  • I would create a website that would serve as a hub for all of our communication tools and key documents. If a staff member had a question or had to reference a document, they would clearly be able to find it on the webpage or through a clearly-marked link from the webpage.

Then I went to my manager, the principal of the school, to share my findings and to get his buy-in on the outcomes I was striving for in the system.

I then developed a few prototypes and met with various staff members to get feedback on each of them. Then I refined them and got more feedback from my principal.

Then I prepared my change management plan and rollout messaging and presentation.

The end product:

No SMS - use Hangout/Gchat groups for your team as a replacement for group texts and direct messages as replacement for text messages (put the “texting” on the same screen as email since we used Gmail, easy to search, and easy to mute notifications when doing focused work)

Everyone had to check the Hangouts 3x a day - once before starting work, once at lunch, and once before leaving for the day. All leaders or people delegating work had to put tasks and updates in the appropriate channels, knowing the recipient was not obligated to check except these three times a day (preserve focus, encourage future planning, allow for course corrections every four hours)

I created the Hub with Google Sites - integrated the task lists (via Trello), Google Calendar, embedded Google Docs, embedded YouTube videos, etc.

I led task list creation meeting each Tuesday, edited on Wednesday and Thursday.

Result - So much praise, shout outs at meetings, shout outs to my manager. People said they were much better able to focus and get updates and respond effectively. Anecdotally far fewer missed deliverables. However, I left before I did any formal surveys as I was still in the process of change management, changing habits. Wasn’t perfect when I left.

Q

Multi-stage growth problems

A

Growth problems: Multi-stage problems *Always* ask whether an exact answer is required first. If estimating. use the compound growth formula: PV * (1 + growth rate) ^ (# of periods). For example, 50m with 2 years of growth at 10%: $50,000,000 * (1 + 0.10) ^ (2 years). Then, the key insight is to prove to yourself that (1.10)^2 is very, very close to adding the growth rates together and then adding 1: Multiplying for exact: 1.10 * 1.10 = 1.21 Adding for estimation: 1 + 0.10 + 0.10 = 1.20 Obviously, the latter route is much easier and for the purposes of estimating gives you a solid footing to work from. Now return to the problem with the estimated approach, the formula is now $50,000,000 * 1.2. This could be simplified to $50 * 1.2 * M, or $60M, very close to accurate.

38
Q

Gut check for growth rate

A

Rule of 72. If you divide 72 by the growth rate, you’ll get the number of periods in which your present value will double. For example, if you have a 6% growth rate, take 72 / 6 which is 12 and you now know that if something is growing at 6% it will double in 12 years. This is useful for two reasons: You can use it to gut check an answer quickly. Given the prior problem we did with the $250M growing at 3%, we could use rule of 72 to determine that the market should double in 24 years. Given we were only asked to calculate 7 years, we would know that if our estimate was anywhere near $500M, something went wrong. Taking it a step further we know 7 / 24 is slightly less than a ⅓ and $250 / 3 is just above $80M, we know that if our answer is above $250M + $80M, which is $330M, something has gone wrong! The other obvious use is finding out how long it will take something to double by simply dividing the growth rate into 72. And as we saw above, once you have that period, you can make rough assumptions that in half the time it would grow roughly 50%, or in a quarter of the time it would grow 25% and so on. Again, these are rough estimates but they can be very useful for ball parking.

39
Q

Rate Change formula

A

Rate change = 1 + rateQuantity + ratePrice + (rateQuantity * ratePrice) Let’s look at why this is true: Say you’ve got a scenario where a firm selling widgets grows sales (the number of units sold) by 50% but in the process drops price 45% in year one. If they had a target to grow overall revenue by 5%, would they achieve it? Revenue0 = Quantity0 * Price0 Revenue1 = (Quantity0 * (1 + 0.5)) * (Price0 * (1 + -0.45)) Revenue1 = Revenue0 * (1 + 0.5) * (1 + -0.45) Revenue1 / Revenue0 = (1 + 0.5) * (1 + -0.45) Rate change = (1 + 0.5) * (1 + -0.45) Rate change = 1 + 0.5 + -0.45 + (0.5 * -0.45) Rate change = 1 + 0.05 + (-0.225) Rate change = 0.825
