Week 3: Delivering Value & Communication
SCRUM Week 3
📘 Summary: SCRUM Week 3 - Delivering Value & Communication
In SCRUM Agile methodology, effective communication and value delivery play pivotal roles in fostering collaboration and project success. Communication should be clear, concise, and tailored to the audience, ensuring messages resonate with their needs and interests. Actively listening, providing practical solutions, and setting clear expectations are essential components of effective communication. Encouraging a feedback loop and following up on interactions contribute to ongoing improvement and commitment.
The importance of a common vocabulary cannot be overstated. Using the right words ensures clarity, reduces misunderstandings, and promotes shared understanding—crucial for effective collaboration. This principle extends to both written and spoken communication. In writing, clarity is paramount, and a feedback loop ensures the message is received as intended. In speaking, prioritizing clarity, adapting to the audience, and utilizing positive reinforcement contribute to impactful communication.
Additionally, the Pareto Principle underscores the significance of focusing efforts on the vital few aspects that yield the most significant results. Multitasking is discouraged as it hampers productivity and quality, leading to cognitive deficits. Finally, an awareness of cognitive biases, such as the halo effect, emphasizes the need for objective judgment to avoid distorted perceptions.

1 Communication
Effective communication hinges on delivering value to your audience. Understand their needs, tailoring messages to resonate with their interests and knowledge.
- Keep communication clear, concise, and relevant, avoiding unnecessary complexity.
- Actively listen, displaying genuine interest in others’ perspectives, and respond thoughtfully.
- Provide practical solutions or insights that address their challenges, emphasizing the benefits.
- Clearly communicate expectations to avoid misunderstandings, promoting efficiency.
- Encourage a feedback loop, learning from input and adapting your communication style accordingly.
- Follow up after interactions to ensure expectations are met, displaying ongoing commitment.
By consistently applying these principles, you establish meaningful connections and contribute value to every interaction.
2 Writing & Speaking
2.1 The mom test
The Mom Test: How to talk to customers & learn if your business is a good idea when everyone is lying to you
The Communication Book provides 44 communication techniques that can be used in everyday situations to improve communication skills.
- The book says you shouldn’t ask your mom whether your business is a good idea, because she loves you and will lie to you. This is technically true, but it misses the point.
- You shouldn’t ask anyone if your business is a good idea.
- It’s a bad question and everyone will lie to you at least a little.
- As a matter of fact, it’s not their responsibility to tell you the truth: It’s your responsibility to find it and it’s worth doing right.
2.2 Words: common vocabulary
Using the right words and a common vocabulary is crucial for effective communication.
It ensures clarity, reduces misunderstandings, and promotes a shared understanding.
Precision in language choice minimizes confusion and facilitates seamless dialogue in various contexts—be it professional interactions or personal relationships.
A common and concrete vocabulary establishes a baseline for meaningful communication, fostering connection and collaboration.
2.3 Writing
In effective writing, clarity is paramount. Clearly articulate your message, tailoring it to your audience’s needs.
Use concise language to convey ideas efficiently, avoiding unnecessary complexity. Employ a feedback loop, welcome input, and adapt your writing style accordingly. Illustrate points with relevant examples for enhanced understanding. Positive reinforcement in your writing can engage readers, and thoughtful follow-up ensures the communication loop is complete. By concentrating on these principles—clarity, conciseness, adaptability, engagement, and follow-up—you create written communication that is not only informative but also impactful and conducive to meaningful interactions.
2.4 Speaking
In effective speaking, prioritize clarity and conciseness to convey your message with precision. Tailor your spoken words to your audience, considering their needs and understanding.
Actively listen, responding thoughtfully to promote engagement. Positive reinforcement in speech fosters a collaborative atmosphere. Adapt your speaking style based on feedback, ensuring effective communication. Utilize relevant examples and visuals to enhance understanding. Follow up verbally to reinforce key points and maintain connections. By concentrating on clarity, audience adaptation, engagement, feedback, and reinforcement, your spoken communication becomes not just informative but also impactful, fostering meaningful interactions and connections with your audience.
3 How to Articulate Complex Ideas
How to Articulate Complex Ideas into Simple Communication: The Ladder of Abstraction.
The ladder of abstraction is relevant because deep understanding alone does not produce clear communication.
You can know a topic thoroughly yet still leave listeners confused or unmoved. The missing skill is translating internal complexity into external clarity without losing accuracy.
It works by repeatedly moving between levels of thought.
- First you grasp the idea as a living whole (right hemisphere).
- Then you climb down into analysis: define terms, test the model, answer the key questions, and extract a one-sentence core (left hemisphere).
- Finally you climb back up, re-embodying the refined idea so it becomes simple, natural, and true again. That full circuit—right → left → right—is what turns knowledge into communication that actually lands.
3.1 Introduction
Deep understanding and vocabulary are necessary but not sufficient for clear \(communication\).
The real skill is translating internal complexity into external clarity without losing fidelity.
This requires both a solid foundation and a specific cognitive movement: traveling up and down the
ladder of abstraction.
3.2 Necessary (the foundation)
- Topic vocabulary — precise terms for the domain so you don’t smuggle in vagueness.
- General vocabulary — ordinary words strong enough to carry weight without sounding childish.
- Mental model understanding — you actually see how the pieces fit and move.
- Core model — the minimal structure that still generates the phenomenon (the “engine”).
- Good simplification choices — a living metaphor plus a one-sentence core.
- WH-questions answered — What is it? How does it work? Why does it matter? When/where does it apply? What breaks it?
These are required. Without them you are either inaccurate or empty.
3.3 Sufficient (the skill)
The core skill that turns the foundation into communication.
Moving up and down the ladder of abstraction — right hemisphere → left hemisphere → right hemisphere again.
This is the actual flow (operating system).
Right hemisphere first Grasp the whole as a living pattern. Feel the shape, the tension, the “what it’s like.” This is pre-verbal or lightly verbal. You sense the core model before you can fully name its parts.
Left hemisphere Climb down the ladder into analysis: break it into components, define terms, answer the WH-questions rigorously, test the metaphor for leaks, write the one-sentence core, check causal links. This is where precision and vocabulary do their work.
Back to right hemisphere Climb back up. Re-embody the analyzed idea so it becomes a living whole again — now clearer, more robust, and speakable. The explanation should feel natural and inevitable, not like a list of bullet points.
Most people get stuck in one hemisphere:
- Pure right: poetic but vague or wrong.
- Pure left: precise but dead, fragmented, and hard to follow.
The skilled communicator repeatedly travels the full circuit. Each pass tightens the core model and improves the simplification.
3.4 Practical sequence
- Sit with the phenomenon until you can feel its shape (right).
- Force a one-sentence core and a strong metaphor (still partly right, beginning left).
- Stress-test both by answering every relevant WH-question and looking for counter-examples (left).
- Discard everything that is not load-bearing.
- Speak or write the idea as a living whole again, using the cleaned core and metaphor (return to right).
- Watch the listener’s face or ask them to reflect it back. Adjust.
When you can move fluidly up and down the ladder — concrete example ↔︎ mid-level mechanism ↔︎ high-level principle — and do so while staying faithful to the core model, the communication becomes both simple and true.
That movement is the sufficient condition. Everything else is preparation for it.
3.5 Example: Machine Learning
One-sentence core
Machine learning is a method that lets computers get better at a task by finding patterns in data, rather than following fixed rules written by humans.
Metaphor
It is like teaching a child to recognize dogs. You do not hand the child a long list of rules (“if it has four legs, fur, a tail, and barks…”). Instead you show thousands of pictures of dogs and not-dogs. Over time the child builds an internal sense of “dog-ness.” Machine learning does the same thing with data and mathematics.
Moving down the ladder (how it actually works)
A machine-learning system is given:
Examples(data)- A
goal(for example: “predict the correct label” or “minimize error”) - A
flexible mathematical structure(usually a model with many adjustable numbers, called parameters)
The system repeatedly adjusts those numbers so that its predictions get closer to the correct answers in the data. This adjustment process is called training. Once trained, the model can make predictions on new, unseen examples.
Common types:
- Supervised learning: The data comes with correct answers (
labeled). The model learns the mapping from input to output. - Unsupervised learning:
No labels. The model looks for natural structure or groupings in the data. - Reinforcement learning: The model learns by
trial and error, receiving rewards or penalties for its actions.
Moving back up the ladder (why it matters)
Instead of programmers having to anticipate every possible case and write explicit rules, the computer discovers useful patterns itself. This is powerful for problems that are too complex, too variable, or too poorly understood for hand-written rules — recognizing speech, recommending products, detecting diseases in medical images, translating languages, or driving cars.
Simple test of understanding If you can answer these clearly, you have the core:
- What is the computer actually
learning? (Patterns / a function from inputs to outputs) Where do the “rules” come from? (They are discovered from data, not written by people)- What makes a
modelgood? (It performs well on new data it has never seen)
That is machine learning at its essence.
4 Clues to communicate
This interview with Vanessa van Edwards, an expert in body language and communication, explains how nonverbal cues, such as posture, gestures, and tone of voice, influence first impressions and social and professional success.
Van Edwards presents scientific research highlighting the importance of nonverbal communication, offering practical advice and techniques to enhance human interactions.
The interview delves into the impact of “cues” on confidence, relationships, and the perception of competence and warmth, suggesting strategies to manage these cues and build more authentic connections.
4.1 Warmth & Competence
Warmth and competence are essential for effective communication because 82% of the impressions we form about others are based on these two factors.
These signals influence how people perceive you and, consequently, how they communicate with you.
- Warmth: Warmth refers to your kindness, likability, and ability to build trust. Warm individuals are often perceived as friendly and approachable.
- Signals of warmth include eye contact, genuine smiles, and an open posture. Warmth can also be conveyed through your voice, such as a warm tone and a gentle pace.
- People perceived as warm are more likely to connect with others and build trusting relationships.
- Competence: Competence refers to your ability, power, and reliability. Competent individuals are seen as intelligent, capable, and efficient.
- Signals of competence include hand gestures, steady eye contact, and a confident voice. Competence can also be expressed through the words you use and how you structure your sentences.
- People perceived as competent are more likely to be taken seriously and respected.
A person with high warmth and high competence is seen as charismatic. These individuals are perceived as pleasant, reliable, and capable, making them more likely to succeed in both personal and professional relationships.
Why are body language and nonverbal signals so important in communication? Our brains tend to believe our gestures more than our words (12.5 times more). This is because it is harder to lie with gestures than with words. Additionally, 82% of the first impression people make is based on the warmth and competence they convey, factors that are primarily communicated through nonverbal signals.
What are the four main channels of signals people send? Signals are divided into four channels: - body language (facial expressions, gestures, posture), - voice (tone, pace, volume), - words (type of language used), - and appearance (colors, jewelry, hairstyle, etc.)
5 Focus to deliver value
Avoiding multitasking and applying the Pareto Principle can significantly enhance focus in communication.
- Multitasking divides attention, reducing the quality of interactions and making it harder to listen actively or respond thoughtfully.
- By focusing on one conversation at a time, you can fully engage, understand nuances, and build stronger connections.
- The Pareto Principle, or the 80/20 rule, suggests that 80% of meaningful outcomes come from 20% of efforts.
- In communication, this means prioritizing key conversations or moments that yield the most impact.
- By concentrating on these high-value interactions and avoiding distractions, you can communicate more effectively, fostering deeper understanding and trust.
5.1 Pareto Principle
The Pareto principle states that for many outcomes, roughly 80% of consequences come from 20% of causes (the “vital few”).
Other names for this principle are the 80/20 rule, the law of the vital few, or the principle of factor sparsity.
- Language: The most frequently used 20% of the words account for 80% of the word occurrences.
- Land Owners: In 1896, Vilfredo Pareto showed that around 80% of the land in Italy was owned by just 20% of population.
- World’s Income: The richest 20% of the humans have 80% of worlds income.
- Health Care: In the US, 20% of the patients use80% of the health care resources.
- Errors: In 2002, Microsoft reported that 80% of the errors and crashes in windows and office are caused by 20% of the bugs involved.
- Business: 20% of the customers are responsible for the 80% of the profit earned and 20% of the complaints received come from 80% of the customers.
- Resources: In home or office, 20 % of the carpet receives 80% of the wear.
- Clothing and Life Style: People wear around 20% of their clothes 80% of the times.
- Fund Raising: The Pareto principle applies to raising funds: 20% of the donors contribute 80% of the total .
5.2 Multitasking
Doing more than one task at a time, especially more than one complex task, takes a toll on productivity.
Although that shouldn’t surprise many people, the extent of the problem might come as a shock. Psychologists who study what happens to cognition (mental processes) when people multitask found that our brains were not designed for it.
Stanford’s professor of communication Clifford Nass, on an NPR broadcast, had clearly summarized the findings:
The research is almost unanimous, which is very rare in social science, and it says that people who chronically multitask show an enormous range of deficits. They’re basically terrible at all sorts of cognitive tasks, including multitasking. People who multitask all the time can’t filter out irrelevancy. They can’t manage a working memory.
They’re chronically distracted [but] they actually think they’re more productive… [They say,] “When I really have to concentrate, I turn off everything and I am laser-focused.”
And unfortunately, they’ve developed habits of mind that make it impossible for them to be laser-focused. They’re suckers for irrelevancy. They just can’t keep on task.
It translates into a:
- Struggle to prioritize: The never-ending change in tasks makes it difficult for us to judge which ones are important, which are urgent and which are just time-filling distractions;
- More error: The overall quality of our work plummets, which results in more manual errors or poor decision-making;
- Productivity loss: Research found that even brief mental blocks created by shifting between tasks can cost as much as 40% of someones productive time.
- At the end multitasking makes us look and feel busy, but actually harm the quality and quantity of our initiatives.
And there are more negative side-effects: because of our brains’ plasticity, when we consistently engage in multi-tasking we reshape our brains for the worse, and we become habituated to this counterproductive way of working.
