Analiza danych

Analiza danych jest ekscytującą dyscypliną, która umożliwia zrozumienie pewnych zjawisk, uzyskanie wglądu i wiedzy na podstawie surowych danych. Pojęcie to oznacza dokładnie przetwarzanie danych za pomocą technik matematycznych i statystycznych w celu uzyskania cennych wniosków, podjęcia ważnych decyzji i opracowania przydatnych produktów. Termin ten wywodzi się od angielskiego data science, często traktowanego jako synonim takich terminów, jak analityka biznesowa, badania operacyjne, business intelligence, wywiad konkurencyjny, analiza i modelowanie danych, a także pozyskiwanie wiedzy. Dzięki takim technologiom, jak języki Python czy R, platformy Hadoop i Spark masz szansę wyciągnąć maksimum wniosków, dostrzec szanse na rozwój swojej organizacji albo przewidzieć i zapobiec zagrożeniom.

Te małe seksowne cyferki. Jak rozwinąć biznes przy użyciu danych, które już mamy

Paul Brown, Dimitri Maex

Czy możesz sobie wyobrazić, że jesteś w stanie zidentyfikować klientów przynoszących największe zyski, wypracować lepszą strategię komunikowania się z nimi i zainspirować ich, aby kupowali więcej? A więc, naprawdę możesz to zrobić. A najlepsze jest to, że możesz to osiągnąć używając danych, które już masz. Wszystko, co robimy, tworzy dane. Za każdym razem, gdy ktoś ogląda coś w sieci, szuka w Google lub nawet przegląda sieć w swoim telefonie, tworzona jest kolejna cząstka danych, które mogą pomóc nam zrozumieć i przewidzieć zachowanie konsumentów. Rewolucja w analizowaniu danych właśnie się toczy i metody oraz narzędzia radzące sobie z tym „potopem danych” stają się coraz prostsze i mniej kosztowne, a jednocześnie bardziej precyzyjne, niż kiedykolwiek wcześniej.  Dimitri Maex, Managing Director globalnej agencji reklamowej OgilvyOne New York i mózg praktyki analitycznej stosowanej w agencji pokazuje, jak możemy przekształcić swoje dane – te małe seksowne cyferki, które mogą zapewnić więcej zysków naszemu biznesowi – w skuteczne strategie prawdziwego wzrostu. W jasnym, przejrzystym stylu wyjaśnia, jak: • Ustalić, którzy klienci mają największy potencjał zwiększenia wartości, po których można spodziewać się większych zakupów, a którzy nie są warci targetowania. • Alokować zasoby marketingowe w najlepszy możliwy sposób. • Przewidzieć, jakich produktów lub usług klienci będą potrzebować w przyszłości. • Zoptymalizować swoją obecność w sieci, aby uzyskać największy zwrot z wyszukiwania.
