I found the echoes of a refined system behind the casual scenery of daily life. Beyond individual silhouettes, a transparent atmosphere called 'philosophy' flows there. It is not merely customer service, but Starbucks as a mechanism to purify the soul. As a mere observer, I witnessed a cold, yet breathtaking warmth within that perfect harmony.

A shop is a carefully constructed environment with no random details. A theatre of perception.

The perception of numbers. 99 roubles is ‘almost a tenner’, not a hundred. The left hemisphere registers the first digit, whilst the right hand is already reaching for the purse. The kopecks force the shop assistant to print a receipt, whilst for the customer they set a mathematical trap: every additional item adds an ‘extra’ rouble. Kopecks work like a silent vacuum cleaner.

Anchoring. Want two hundred? Put a ‘250’ price tag on, cross it out and write ‘200’. The inflated price becomes the reference point; the real one seems unreasonably low. The anchoring effect (Kahneman, Tversky). ‘Thinking, Fast and Slow’ — a must-have.

Visual logistics. Expensive items at eye level. Know how to bend down. Products nearing their expiry date — at the front, fresh ones — further back. Cheese next to bread — an associative sequence, an impulse buy. Little animals on the boxes look the child in the eye. Parents buy.

The psychology of spending. Smaller packaging loses out when calculated per litre. People overpay for the illusion of control, and end up visiting the shop more often.

Apps and loyalty cards. Data collection. You scan your receipt, get cashback — the shop gets a digital profile: what, when, how often. The algorithm knows the moment of weakness and will send a notification. A loyalty card isn’t a ticket to a world of benefits, but a collar with a tracking beacon.

Music. Wear headphones. Slow music keeps you lingering by the shelves; classical music boosts sales of expensive items. Calm music is for long strolls; impulsive music is for quick decisions.

A clear shopping list is your safeguard. The mechanisms work flawlessly.

The shop manages the wallet. The next mechanism is the heart.

An excerpt from the treatise *The Anatomy of Thought*.

Heyyyyyy 🐧

Today, I want to step away from the pure code and talk about something broader and, in my opinion, just as fascinating: the creation of a complete information system. Something you probably DON'T know... I'm studying systems analysis, and one of the clearest things I've learned is that programming is just one piece of a much larger puzzle.

When we think about an information system, our minds often go straight to the lines of code. However, a robust and functional system is the result of a much more complex process involving various stages and roles. From the initial idea to its launch and maintenance, each step is crucial for success.

Key Stages in System Creation

Based on what I've learned, I'd like to share some of the fundamental stages involved in creating an information system:

Requirements Analysis: This is the starting point! Before writing a single line of code, it's vital to thoroughly understand the needs of the client or users. What problem are we trying to solve? What functionalities are essential? This involves interviews, surveys, analysis of the current situation, and the exhaustive documentation of requirements.

System Design: Once we have a clear understanding of the requirements, we move on to designing the system architecture. This includes:

Logical Design: Defining the structure of the data, the processes, the interfaces, and how the different components will interact.

Physical Design: Specifying the hardware, software, network infrastructure, and other technical elements necessary to implement the system.

Implementation (Where Programming Comes In!): This is the stage where the design is translated into functional code. Programmers develop the different modules and components of the system using the appropriate languages and tools.

Testing: Absolutely crucial for ensuring quality! Different types of tests are performed (unit tests, integration tests, system tests, user acceptance tests) to identify and correct errors before going live.

Deployment (Going Live): Once the system has been tested and validated, it is implemented in the environment where it will be used. This may involve installation on servers, network configuration, and data migration.

Maintenance: The work doesn't end with deployment! Continuous maintenance is essential to correct errors, perform updates, add new functionalities, and ensure the system continues to function optimally over time.
