This is a review of the lectures and study sessions from a student who participated in the Inflearn Warming-up Club 3rd Cohort. 1. Lecture This lecture clearly explained what a PM is and what aspects a PM should focus on. Everything covered in the lecture was clear. It felt like an introduction to psychology or the principles of business administration, but ultimately, it convincingly argued based on various grounds that a PM is someone who needs to handle the tasks that someone must consider for the continuation and growth of a business. It also allowed me, as a working professional, to gain metacognition. In the first week's session, 'What a PM Does,' I was awakened, both verbally and in writing, to how easy the tasks I perform at work are. I was hit with the hard truth. Any planner or PM who feels ambiguity in their role at work should definitely take this course. The reason is that it helps people with the job title of 'planner' to grasp the direction they should ultimately move towards. We cannot realistically change our current roles or abandon our tasks. However, we come to know the direction in which we need to grow steadily and what is necessary. 2. Study Session I believe that the Inflearn Warming-up Club study schedule is well-organized, considering all students. If you are someone who can focus solely on the lectures without juggling other commitments, you can grow significantly in a short period by studying in-depth for about 4 hours a day according to the curriculum. For working professionals, the schedule is not overwhelming. However, there is a lot to think about regarding the concepts presented in the lectures, so you need to pause and reflect from time to time. Considering this, absorbing the theory alone can take 1-2 hours, so just listening to the lectures will take up your sleep time. I usually go to bed between 11 PM and 12 AM, but during the study period, I went to bed between 1 AM and 2 AM, and the time I invested in hobbies also gradually decreased. This is a human phenomenon. Due to the nature of working professionals being exhausted on weekdays, it is difficult to find the time to deeply contemplate things despite wanting to. Realistically, it was difficult to find an extra 1-2 hours of self-study, so I am making a lengthy excuse for not properly understanding the content. Therefore, I originally planned to take a data analysis course in April, but I have changed my plan to deepen the learning of the theories learned in this PM/PO course. I will write down and elaborate on cases where the theories learned over the past month can be applied to practical work. Actually, I have a lot of feedback to give to Inflearn regarding the study sessions, but it's hard to write more in this format. I would be willing to participate in an 'in-depth interview,' which was a key method taught in the lecture for understanding customers, if the opportunity arises. 3. Conclusion During the study period, I was curious about how others were studying, and the coach arranged an opportunity to meet the study group members. This is my first time participating in an external meeting related to my job, so I am excited and looking forward to it. Under the name of products, we will share knowledge on a vast range (general knowledge related to sales/marketing/development/operations) and receive a lot of inspiration from each other. It will be a truly meaningful conclusion. I would recommend this lecture to anyone who has the will to overcome weekday fatigue for a month.

I had previously received a lot of help from Minwoo's newsletter and content, so I applied for the course without hesitation. It was a lecture that greatly increased my understanding of PM/PO work and product growth, and it was the most helpful lecture I've ever taken related to my job. Since PO/PM work is more about judgment and perspective than technology and knowledge-based work, it felt very vague, but it was really helpful in setting direction and carrying out my work because you clearly shared it with a lot of insights from the field. Thank you!

I realized that the role of a product manager is not to 'launch a product' but to 'create performance through customer value and business value'. At my current company, I only worked in the [Planning -> Development -> New Project Planning (Repeat)] fashion, so it was difficult to hear customer feedback. It felt like a 3-minute plan, like a 3-minute curry. In the midst of that, I was thinking about how to collect/measure/utilize quantitative customer feedback, and I happened to listen to Minwoo's lecture. I was really impressed by the fact that you can structure indicator setting and problem discovery through a framework. It may be difficult to apply it to my current company right away, but it was a great help in setting a benchmark for the company I will transfer to and setting the direction of my work. Thank you for sharing your valuable knowledge and lectures for PMs!

What you will gain after the course

  • How to precisely measure and improve product data using product metrics

  • Research techniques (interviews, usability testing) for identifying customer problems

  • Product Discovery Framework for Driving Business Results

  • Practical explanations and examples regarding hypothesis (assumptions) setting and verification

  • Product Growth: How to systematically grow a product based on an understanding of growth levers and growth models, rather than just blindly running A/B tests.

  • How to collaborate wisely with teammates as a Product Manager

A lecture for junior PMs/POs who do not have a good mentor by their side.

Working and learning alongside a great mentor is likely the wish of many junior PMs and POs.

Watching and learning from the side how to define problems, how to think and make decisions, how to handle various situations that arise while working, and how to structure work and produce results becomes a shortcut to growth.

However, not everyone is lucky enough to work with a great mentor. Most find themselves in a situation where they must work on their own without a senior to look up to and learn from. Hoping to be of help to the junior PMs/POs who are struggling today, I have generously included various techniques and mental models that I have acquired through learning, execution, and deep reflection.

Through this course, which directly reflects my own thought process, I hope you will achieve these kinds of transformations.

  • Defining problems sharply, specifically identifying and defining problems that are 'worth solving' for a product organization.

  • Utilizing quantitative data and qualitative customer research in the right places.

  • Working in a way that proactively establishes and validates hypotheses, rather than simply gathering requirements and designing screens.

  • Approaching product tasks systematically by structuring them, without getting lost on where to start.

Hello, I'm Minwoo Kim, the creator of this course.

In this course, I have included everything I have learned, practiced, and built through trial and error while working in the IT startup industry for over 10 years. If you enjoyed my previous content, I believe you will be satisfied with this course as well. As always, I have made an effort to include only the essentials without any fluff or exaggeration.

You can view my previous posts and content at the links below.

For speaking engagements or collaboration inquiries, please email minwoo@minwookim.kr. Thank you.

The background behind the creation of this course

I first started becoming interested in the Product Manager role in 2012. At that time, only the "Service Planner" role existed in Korea. Since there was nowhere to learn about product management in Korea, I had to learn from experts abroad.

I studied using content from Google's Ken Norton, Marty Cagan who wrote , Kissmetrics founder Hiten Shah, Lean Startup mentor Steve Blank, Y Combinator founder Paul Graham, and many other great individuals (including Lenny Rachitsky, Julie Zhuo, and Shreyas Doshi, who are well-known in Korea these days).

Due to my nature of reading voraciously and feeling unsatisfied unless I immediately put what I've learned into practice, I applied my studies to my work right away and learned further through trial and error on the job. As a result, I developed a unique way of working that differed from other service planners in Korea at the time.

  • Rather than immediately building the features requested by customers or stakeholders, I strove to meet customers in person to understand the problems and their context,

  • Rather than creating planning documents (functional specifications, wireframes) and managing projects, I focused on clearly defining and testing risky assumptions that required validation,

  • Rather than just launching a feature and finishing there, I strove to precisely track metrics and user behavior using product analytics.

This approach was not common at first, but around 2020, many product organizations began striving to work this way. Thanks to this, I had the opportunity to write, give lectures, and coach other product organizations and individuals.

I have poured everything I've accumulated over the past 10 years—from greedily studying and applying what I learned, to sharing knowledge through writing and content, and teaching through coaching—into this course. I hope it proves helpful to those starting their careers as PMs/POs, as well as those already working in these roles who have concerns about their professional expertise.

Leading product organizations are increasingly looking for PMs/POs with these capabilities.

  • Data-driven problem-solving skills

  • Hypothesis formulation and quantitative/qualitative validation skills

  • Customer-centric ability to define and solve problems

  • The ability to grow products and create business impact


However, many PMs/POs are still stuck in these outdated roles.

  • Gathering requirements from stakeholders

  • Creating planning documents (functional specifications, wireframes)

  • Managing projects to ensure features are released within the schedule


These PM/POs are nothing more than parts of a feature factory that is only focused on planning and launching features. Working this way makes it difficult to be recognized for your value in the market, no matter how long your career is.

This course provides the foundational knowledge for you to become a competent PM/PO who contributes unique expertise to a product organization, rather than just being a cog in a feature factory.

We provide step-by-step explanations of difficult and unfamiliar concepts such as problem definition, hypothesis setting and validation, thinking from the customer's perspective, data utilization, and creating business impact, and help you make them your own using various cases and references.

🐧🍼Do you know about Penguin Milk? It is said that father Emperor Penguins provide their chicks, who cannot yet eat large fish, with "penguin milk"—food they have already half-digested themselves.

I created this lecture with the same heart as one making "penguin milk." I have thoroughly chewed over everything I’ve learned, experienced, pondered, and discovered through trial and error over the past 10 years, so that I can deliver it in a way that is easy for you to digest.

What you can learn from this course

1. The Unique Professionalism of a Product Manager

  • A PM is not a 'handyman' who only cleans up after the team and handles stakeholder communication, but someone who contributes their unique expertise to the product organization.

  • We will show you what expertise a PM should contribute to the organization and how to acquire such expertise.


2. Problem: Properly Defining and Solving It

  • I hear from many places that defining the problem is important.

    However, it is difficult to learn how to define a problem well.

  • As a product manager, I will show you how to think accurately and rigorously about problems.

  • Not all customer problems are problems worth solving within a product. We will provide the criteria for determining which problems are worth addressing in your product.


3. Powerful tools for understanding customers: Designing and conducting in-depth interviews and usability tests

  • Great products come from an understanding of the customer.

    The best way to understand customers well is to meet them in person and conduct research.

  • We will show you the minimum research methodologies a PM should possess in an organization without a professional researcher.

  • We'll show you how to design and conduct In-Depth Interviews and Usability Tests, what common mistakes can be made, and how to avoid them.

  • We will show you how to obtain the information needed for decision-making by starting research from the decision-making process and designing business questions and research questions, which is different from blindly creating surveys and meeting customers.


4. Developing Data Expertise: Working Based on Data

  • The phrase 'data-driven work' is used in many different contexts. Everything from monitoring business metrics to building recommendation algorithms or utilizing artificial intelligence is grouped under the single term 'data.'

  • Therefore, for those entering the field for the first time, it is difficult to know what PMs do with data, what competencies they need to have for this, and what they should study.

  • To ensure there is no more confusion, I will explain what it means for a PM to utilize data effectively and what you need to do to build data expertise.


5. Product Metric Framework

  • Through various metrics, PMs can understand how customers are using the product and how much business value the product is creating.

  • The ability to make decisions based on metrics is one of the core expertises of a PM.

  • We will show you which metrics to monitor from various perspectives such as Acquisition, Activation, Engagement, Retention, and Monetization, as well as how to interpret these metrics and make decisions.



6. Product Discovery: The Comprehensive Art of Setting and Validating Hypotheses

  • A PM in a modern product organization is not someone who receives "requirements" from "stakeholders" and creates "functional specifications and wireframes." (That is the work of planners at agencies or SI firms.)

  • A PM is someone who provides value by solving customer problems and creates business value for our company.

  • To achieve this, the capability for "product discovery"—the process of finding a product that is valuable, usable, feasible, and viable—is essential.

  • Product discovery is a comprehensive art form ranging from hypothesis setting to validation. We will show you how to approach this process.

  • In particular, we will explain concepts such as assumptions and testing, which can feel abstract, in detail and show you how to apply these concepts in actual work.


7. Growing the Product: Product Growth

  • The PM's role does not end with creating and launching or deploying a product or feature.

  • You must also know how to ensure that customers/users actually use the product well and create business value for the company.

  • We will show you how product organizations can contribute to growth by improving Acquisition, Activation, Engagement, Retention, and Monetization metrics.


8. Collaboration

  • Modern product organizations do not work in a way where 'planning,' 'development,' and 'design' teams operate separately; instead, PMs, designers, and engineers work closely together within a single team.

  • I will explain why we work this way and how you can collaborate effectively as a PM in this environment.


Reviews from those who took the course first

(These are genuine reviews from students who paid for the course. They are not reviews from trial groups or requested from acquaintances.)

Ok-yeop Heo (Product Manager, Wolgeupjaengi Bujadeul)

This is a lecture that I highly recommend not only for POs/PMs starting their careers but also for those currently working in the field.

Beyond simply conveying theory, the instructor explained various situations, issues, and solutions that can occur throughout the entire product development cycle using diverse cases and episodes, allowing me to gain insights that can be immediately applied to my work.

In particular, through the metric setting framework introduced in the lecture, I was able to learn a framework of thinking necessary for measuring and improving product growth using metrics, going beyond simply defining them.

I highly recommend this course to those who want to take their expertise as a PO/PM to the next level.

Miryeong Lee (Product Manager, Lycle Company)

It will be worth every penny!

What defines a great PM? If the first thing that came to your mind was wireframes, you need to take this course right away. A great PM must understand the business and discover problems that are truly worth solving.

By taking Min-woo's lecture, you can understand the important values that a PM should keep in mind and learn various actions for execution. In particular, the 'Customer Research Design' and 'Metric Setting Framework' chapters were something I could apply directly to my practical work.

Equip yourself with various tools as a PM through a solid theoretical foundation and diverse real-world application cases!

Hyunjin Yoon (Product Designer, Pickle Plus)

I felt that this was a lecture that balanced theory and practice, covering everything from the definition of PM/PO to frameworks and metrics.

While many contents usually just hand you a bow and teach you how to fire as many arrows as possible, this course meticulously covers everything from the craftsmanship of the bow to the technique of shooting, and then checks whether you are holding the bow with the correct posture and aiming with true precision. For this reason, I believe this course is valuable not only for beginners but for everyone.

I felt that the lecture proceeded from beginning to end on the premise of critical thinking. I believe this is the most important part of working in the industry, and it is a term that is actually mentioned several times. Since critical thinking is not something that happens just because you know it, but rather something that must be internalized, I think it is in some ways the most difficult part to learn. However, because the lecture consistently speaks based on this mindset, I felt that I was naturally being trained to some extent as I followed along.

Finally, it sends chills down my spine to think that if I hadn't taken this course, I might never have known what the PO role truly entails. I hope many people watch this lecture so they can collaborate with a proper understanding of each other's roles. Thank you for creating such a great course, and I definitely want to take your next one as well.

Sunghoon Jeong (Former Class101 Growth, CRM)

"So how should I work?", "What kind of person am I?"

I recommend this lecture to PMs/POs who have these concerns. I believe your current struggles stem from not having a mental model.

Through this lecture, I believe you will gain everything from the definition of the role to the mindset, basic practical tasks, and common mistakes, providing you with not only a mental model for the previously abstract PM/PO role but also significant help in your actual work.

I expect that this mental model will serve as a strong foundation for aspiring PMs and POs to independently determine how to work and what to study in the future. I highly recommend this course to anyone who feels lost on their journey as a PM or PO!

Jeonghee Baek (Data Analyst, TMAP Mobility)

As a data analyst, I have always wondered how the analysis I perform impacts the product. Rather than simply refining data and creating metrics and dashboards according to requirements, I wanted to identify metrics that could directly contribute to product growth.

Through this course, I was able to learn how to define problems and set metrics, which allowed me to think deeply about the direction our product should take.

It was a huge help because they provided not only high-quality lectures but also so many great references to look into!

Eunkyung Lee (Senior Product Marketing Manager, Landing AI)

As I am currently working as a Product Marketer, this lecture was very beneficial as many parts regarding the scope of work and approach of a Product Manager were applicable to me. I feel like I've gained tools that will allow me to collaborate more efficiently in the future while also considering the Product Team's perspective.

While the knowledge applicable to actual work was helpful, I think a major benefit of the lecture was that it provided an opportunity to reflect on and rethink my work methods and approaches. I believe it will serve as a starting point for those working in product-related fields to gain diverse perspectives and insights.

    I think there are many people who are new to PM roles or preparing to transition and do not clearly understand what role a PM is in an organization and what capabilities they need to have. I also faced similar situations and problems, and while performing PM roles that I did not even understand properly, I discovered this lecture. I have always found the product and growth-related newsletters on the site "Thinker-Practitioner" operated by the instructor to be informative, so I trusted the lectures provided and paid for them right away. The main content of the lecture that I felt was "the transfer of knowledge that serves as a foundation for becoming a capable PM who contributes to the product organization based on unique expertise." This lecture does not simply list methodologies, but makes you think about what kind of perspective and attitude you should have as a PM. While taking the lecture, I reflected on how many stupid things I have done while working on projects. I highly recommend this lecture to anyone who wants to properly perform the role of a PM and create real results!

    "Is what I know really what I know?" I try to think critically, so I often wonder if I have misunderstood or only acquired fragmentary knowledge. And when I find this part, I learn a lot. This lecture was a lecture that filled this tendency of mine so well. I think it will prevent a lot of trial and error in advance because it explains common misunderstandings and easy traps that we can easily fall into, based on Minwoo's experience. I highly recommend this lecture to those who want to expand their own way of thinking!

    This is a lecture that I would like to hear from both POs/PMs who are just starting their careers and those who are currently working in the field as POs/PMs. Beyond simple theoretical delivery, it explains various situations and issues that can occur throughout the entire product development cycle, as well as solutions to these issues, using various cases and episodes, so I was able to gain insights that can be applied directly to the field. In particular, through the indicator setting framework introduced in the lecture, I was able to learn the framework of thinking necessary to measure and improve product growth by utilizing indicators, rather than simply defining indicators. I highly recommend this lecture to those who want to take their expertise as a PO/PM to the next level.

    I have always loved Minwoo's content, and I expected this lecture to be concise and to the point. However, this lecture was more than that. It felt like it distilled down the important content. In particular, it was a lecture that clearly explained what a PM should do to create a successful product. When I shared it with my team, everyone praised it as being worth more than 10 times the tuition fee. If you are thinking about taking the lecture, don't hesitate and definitely take it!

    I took the course because I was working as a developer at an early startup and now I am doing PM work for the first time. It was good to learn what role a PM should play at each stage of product development and operation. Since I was preparing to launch a new product while working on my first PM job, I was able to apply the lecture content by following each chapter. The lecture was also very helpful when conducting user interviews and setting up a roadmap right after the launch. I reviewed the part about Product Discovery several times in particular. I was able to structure our goals by going through the process of planning product strategies and creating opportunity solution trees with the team. Among the concepts I learned in the lecture, there were many that I have not yet applied in practice, such as using indicators and data, so I plan to refer to the lecture regularly and learn while working as a PM. I took the course with gratitude to Minwoo because it relieved the frustration I had when I first prepared to be a PM. I would like to recommend it to PMs who are just starting out like me, and I think there is enough insight to learn even if you already have experience!
