Room-Mates App

54% of the world’s population live in urban communities And the average marriage age for men is 29 (up from 26 two decades ago) and for women is 27 (up from 23 in the same time period). Given these trends, city dwellers tend to spend most of their twenties living with roommates. Finding and keeping a good roommate, however, gets harder as more people swarm into cities. The Problem It is getting harder and harder to find […]

Information architecture

Information architecture or shortly IA is the art of organising the content in a logical and user-friendly way. If the IA is done right the user can easily navigate through the product we are designing. We can find the roots of Information Architecture back in library science and cognitive psychology. Imagine yourself as a digital librarian – in other words the information architect organises content across digital product. Main questions which should be asked are: Where should […]

Wok Bar App

What is Wok Bar? At the university we have an in-house canteen, Tim’s Diner, which serves a range of delicious meals. An option we have is the Wok Bar. It is a place where you can choose your ingredients, sauce, protein, and it’s cooked up in front of you. One day it could be curry, another stir fry, another pasta. This has proven to be a very popular option, with queues building up and waits that feel […]

Users are asked about their travel experience and what they are usually do while booking a flight online. They are also asked about their last trip and which were their main problems and the communication channels they used. Afterwards they perform a test with particular goal to book a trip on desktop versions of the websites of Aer Lingus […]

Online survey

With six usual questions I tried to save people’s time and in the same time to take the most of the date they have provided. Design survey 1. When was the last time when you visit airline website? I spotted one mistake […]

Грешки тип 1 и 2 при A/B тестване

Реших да разгледам една доста интересна тема, а именно Error Type 1 and 2 в A/B testing. По подразбиране в статистическото хипотезно тестване нито един тест не е 100% точен: това е защото се разчита на вероятности в експеримента. Когато онлайн маркетолози и учени тестват хипотеза, и двете групи търсят статистически релевантни резултати. Достигнатите резултати трябва да бъдат в рамките на статистическата грешка : обикновено 95%. Въпреки че достоверността на тестваните хипотези е много голяма има вероятност […]
