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
automates the calculation of the above mentioned data.
History
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.).
5G Applications
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,
entertainment industry,
education,
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 a server platform for working with JavaScript through the V8 engine. JavaScript performs the action on the client side, and Node let the commands, written on JS to be implemented on the server. With Node, front-end programmers can write full-fledged software applications. Node can call commands from JavaScript code, work with external libraries, and act as a web server.
Node Advantages
Node is easier to scale. When thousands of users connect to the server at the same time, Node works asynchronously, that is, it sets priorities and allocates resources more intelligently. Java, for example, allocates a separate stream for each connection.
Features
Asynchronous scripts based on events. All Node.js APIs are asynchronous: non-blocking downloads. In essence, this means that a Node based server never expects data to be returned from the API. After the call, the server proceeds to the next API, and the Node.js events notification mechanism helps the server to get a response from the previous call.
Very fast. Being built on the Google Chrome V8 JavaScript browser, the Node.js library runs very quickly in code.
Single-threaded but easily scalable - Node.js uses a single-threaded model with an event loop. The Event engine helps the server respond in a non blocking way and provides high scalability, unlike traditional servers that create limited threads for processing requests. Node uses a single-threaded program, and the same program can serve much more requests than traditional servers, such as the Apache HTTP Server.
No buffering - Node.js apps do not buffer data. Apps simply output data in parts.
Where is Node.js used?
Node.js has established itself as an ideal technological solution in the following areas:
Input / Output applications
Streaming apps
Intensive use of data in real time (DIRT)
JSON API based applications
Node is successfully used by such large companies as eBay,Microsoft, PayPal, General Electric, Uber, GoDaddy, Wikipins, Yahoo!.
