'Book Notes': aren’t book reviews, summaries, or recommendations. They’re closer to a "reading diary": one's personal experience of what a book stirs up in them as they move through it. Book Notes' sometimes include a few favorite lines or small extracts - not to “capture the book,” but to capture the moment. Occasionally, a passage lights something up inside the reader that’s unrelated (or only loosely related) to the book’s main subject. These notes also attempt to put that spark into words.

The font size is not small, decent and good for faster read and reading in non-cozy settings like travelling.

With change in technology the expectations and core qualities of a successful leader are changing. This book focuses on how 'Humility' is now one of these core qualities - from something of a guarded embarrassing or detested character, this 'Humility' is now much needed ingredient of a successful leader. In other words, as per author Humility is now a strength no longer a weakness.

Leadership is an Alchemy. It is neither science nor art, but sometimes neither and again sometimes it is
...I crossed the bridge
I crossed the bridge,
Running from East to West,
Daring fog, rain, wind,
Trying hard to be visible -
among zooming invisibles.
Finally - sitting in hall,
drenched with light all over,
Waking and Feeding the core,
After a long eons of break.
Sweet surprising every minute -
The core being core and not rocky.
Three Sprints per Period: The NOS Model (Normal | Overhead | Stretch)
Modern engineering work rarely fits neatly into a single, fixed sprint plan. As teams grow and systems move closer to GA, unpredictability becomes the norm rather than the exception. The NOS model is a simple structural change that acknowledges this reality - without adding process overhead.
NOS = Normal | Overhead | Stretch
Background
Today, each team typically creates one sprint per period (usually bi-weekly), for example:
CrewName 10/15–10/28
In practice, this model breaks down in several ways.
Key Challenges
1. Unavoidable Overhead
New work routinely appears mid-sprint - urgent customer issues, Customer alarms, SME consultations, release - driven priorities. Continuous re-prioritization is unavoidable, especially during GA phases. A rigid 15-day commitment does not reflect how work actually happens.
2. No Clear Space for Stretch Goals
We lack a clean mechanism to track opportunistic or “nice-to-have” work that teams can take on when capacity opens up.
3. Label Fatigue
Using Jira labels to distinguish planned, unplanned, and stretch work has proven cumbersome and inconsistent. Labels add cognitive overhead without solving the underlying issue.
4. Unreliable Metrics
When priorities shift mid-sprint, sprint metrics lose meaning. Planned vs. completed work, planning accuracy, and predictability all become noisy, limiting our ability to learn and improve.
Proposal: The NOS Sprint Model
For every sprint period, instead of creating one sprint , create three parallel sprints :
