Lean UX dla zespołów Agile. Projektowane doskonałych wrażeń użytkownika. Wydanie II

Jeff Gothelf, Josh Seiden

Zaprojektowanie doświadczeń użytkownika (UX) jest najłatwiejsze, jeśli do pracy i testów angażuje się... rzeczywistych userów i pozyskuje od nich informację zwrotną. Podejście lean UX łączy podstawy myślenia projektowego i programowania zwinnego. Myślenie projektowe rozszerza zakres pracy poza interfejsy i artefakty, opierając się na współpracy, iteracjach, budowaniu i empatii. Metodologie zwinne polegają na przeorientowaniu wytwarzania oprogramowania na krótsze cykle, regularnym dostarczaniu wartości i ciągłym uczeniu się. Ważne jest szybkie zapoznawanie klientów z pomysłami i ciągłe dostosowywanie się do nowo zdobytej wiedzy. W ten sposób lean UX znakomicie sprawdza się w projektowaniu wrażeń użytkownika w środowiskach zwinnych. Ta książka jest drugim wydaniem znakomitego podręcznika, w którym opisano wartościowe zasady, taktyki i techniki polecane dla zespołów pracujących nad produktem, aby mogły one w zwinnym procesie ująć projektowanie, eksperymenty oraz nieustanne doskonalenie rozwiązań. W książce pokazano, jak ściśle współpracować oraz wcześnie i odpowiednio często pozyskiwać informacje zwrotne. Praktyczne wskazówki ułatwią wdrożenie zasad kierowania projektowaniem w krótkich, powtarzalnych cyklach, co pozwoli na ocenę, które działania są najlepsze dla firmy i użytkownika. To cenna pozycja zarówno dla projektantów UX, jak i dla programistów czy menedżerów, którzy znajdą w niej źródło pożytecznych wskazówek ułatwiających uzyskanie doskonałych wrażeń użytkownika. W tej książce: zarys metodologii lean UX i zasady projektowania doświadczeń użytkownika etapy cyklu lean UX pozyskiwanie informacji zwrotnych i ich wykorzystywanie integracja praktyk lean UX w obrębie organizacji rola podejścia lean UX w typowym środowisku zwinnego wytwarzania oprogramowania Lean UX: zwinne zespoły projektują najlepsze interakcje!
