Net Promoter Score (NPS) is an index that identifies customer loyalty to a product or company and is used to assess readiness for re-purchases.
How It Works
Measuring the NPS loyalty index involves several steps:
Consumers are asked to answer the question “What is the probability that you would recommend a company
/product/brand to your friends/acquaintances/colleagues?” On a 10-point scale, where 0 corresponds to the answer “I will not recommend it in any way”, and 10 - “ I will surely recommend. "
Based on the estimates obtained, all consumers are divided into 3 groups:
9-10 points - product/brand promoters,
7-8 points - passives,
0-6 points - detractors.
Calculation of the NPS index itself. NPS =% supporters -% critics
As a result, the the user’s loyalty score calculated on the scale from -100 to 100. If all the customers are willing to recommend the product, the score will be about 90-100, if they are not willing to recommend it - the NPS will drop to -90-100 points.
NPS trade mark was registered for the marketing tool, which automate
s the calculation of the above mentioned data.
Frederick Reichheld is considered the founder of the method, who first announced the method in the article “One Number You Need to Grow”, published in the Harvard Business Review in December 2003. In 2006, he released a book entitled “The Ultimate Question: Driving Good Profits and True Growth”. He continued his arguments on the loyalty, profitability and growth of the company.
In 2001, Reichheld conducted research in more than 400 American companies, where the main task was to measure the influence of customer loyalty (measured by NPS) on its growth rate. The main result was the conclusion that the average NPS by market in the industry was 16%, but for companies such as eBay and Amazon NPS it was 75%. Reichheld does not say that communication is present everywhere: it is absent altogether in monopolistic markets. However, industries such as passenger air travel, insurance and car rental have become a prime example of interconnection. This is obvious, since these companies are service providers, where customer satisfaction and loyalty depend on the level of customer service. As a result, many companies have become adherents of this technology, including Apple, American Express, eBay, Amazon, Allianz, P & G, Intuit,, Philips, etc.
For certain industries, especially software
, it has been proven that Detractors often stay with the company while Passives leave. This seems to be a relatively high barrier to trade.
Faced with criticism of the promoter's score, proponents of the network promoter's approach stated that the proposed statistical analysis only proved that the "recommendation" problem was similar to other indicators in predictive capacity, but failed to solve the real problem and this is the core of the argument presented by Reichheld.
Proponents of the method also argue that third-party data analysis is not as good as analyzing the company in its own set of customers, and the actual benefits of the method (simple communication concepts, short survey, customer follow-up features ) exceed any statistical disadvantage of the approach. They also allow inquiries using any other issues to be used in the net promotion system, as long as it meets the criteria to securely classify customers as promoters, passives and detractors.
is the fifth generation mobile communication technology based on the IMT-2020 standard. The speed of Internet access in the 5G network is predicted at around 10 Gbit/s.
5G reduces the signal delay to one millisecond - against 10 milliseconds on 4G networks and 100 milliseconds in 3G.
New generations of mobile communication appear every 10 years. Within this interim, time is spent on the development of technology, standards and infrastructure upgrades.
It is expected that the 5G network capacity will be enough to serve more than 1 million devices per 1 km² at an average speed of 100 Mbps.

Who Deals with 5G Networks in the World
Today 5G technologies are used by:
research laboratories (for example, the 5G Lab Germany laboratory at the Dresden Technical University);
mobile operators (British Vodafone, American Verizon and AT&T, Japanese NTT DoCoMo, Swedish Teliaetc);
telecom equipment suppliers Swedish Ericsson, (Chinese Huawei, Finnish Nokia, South Korean Samsung, etc.).
These apps and services require significantly higher characteristics of a mobile Internet connection, which cannot be implemented in existing commercial LTE networks.
It is expected that 5G networks will allow connecting many devices capable of establishing billions of connections, due to which it will be possible to create new services in:
Tactile Internet (transmission of touch),
IT and Telecom,
automotive industry - self-driving cars,
agriculture and many others.
Due to the 5G networks, it will also be possible to improve the quality of use of already existing services, where large volumes of traffic are involved.
Launch of the World's First 5G Network
October 1, 2018 Verizon announced the launch of the world's first commercial network of the fifth generation (5G). The operator has deployed it in four US cities: Sacramento, Houston, Los Angeles, and Indianapolis. The company officially declared Houston resident Clayton Harris "the first customer of the 5G network in the world,” which provides an average speed of 300 Mbit/s, and the maximum of 940 Mbit/s.
is an open source general purpose PHP framework. The Laravel creators themselves called it “framework for artisans”, hinting that the platform gives programmers complete creative freedom without putting any obstacles in the development process.
MVC Code Structure
The Laravel framework code structure corresponds to the MVC design pattern, i.e. programmers can select views, models, and controllers.
MVC has proven to be a time-tested solution to the challenge of creating effective app structure.
This development pattern allows making the code more readable, and the creation process comfortable by demarcating the work of backend and frontend developers.
Artisan is a Laravel console, in the commands arsenal. There is work with controllers and models, migrations, authorization and other basic framework components.
A sort of version control for the database table structure. Each migration file contains either a table structure or changes in its structure.
The process of building new database entities in the Laravel framework happens when you create a migration and launch it with the help of special artisan console commands.
Blade is its own template engine with a set of its own directives. Its working principle is similar to most of its fellows - Smarty, Twig, etc.
Twitter Bootstrap and jQuery out of the box
After installing the Laravel framework, the developer has at his disposal the app.css and app.js files, which are the BootStrap and jQuery of the latest versions that were assembled and minimized at the time of the Laravel release.
ORM is a programming technology built to make it easier for developers to work with the database by providing API methods for standard operations (fetching, adding, updating, deleting, etc.).
Various ways of Working with Sessions
Session objects are stored on the server, therefore, they can be easily and conveniently manipulated by the server programming languages, as well as assigning them to various storages.
Laravel developers took the advantage of this feature, having introduced into the framework the ability to choose how to store session objects using different technologies.
file storage on the server - standard session objects;
saving data in the database;
temporary php array
With Laravel, as well as any other framework, programmers can make completely different types of sites, starting with landing pages and ending with social networks.
This is their fundamental difference from CMS, which, for the most part, are highly specialized.
