Description : Мы привыкли считать, что процессы и менеджмент — это что-то скучное и унылое, а стартапы — динамичное и увлекательное, где нет места никаким правилам. Однако верно как раз обратное: создание стартапа должно быть подчинено четкой методике, имеющей строго определенные шаги. Основная идея метода «экономичный стартап», разработанного Эриком Рисом, заключается в быстром тестировании идей новых продуктов на реальных потребителях и постоянной корректировке бизнес-модели, с тем чтобы начинать масштабные вложения только тогда, когда идея подтверждена фактами. Кто уже познакомился с этой книгой, говорит о ней так: если вы предприниматель, срочно бросайте все дела, садитесь и читайте! И пусть вас не смущают слова «бизнес с нуля» в названии. Предприниматели по духу есть в разных компаниях, а уметь постоянно анализировать бизнес-модель и вовремя вносить в нее коррективы нужно любому бизнесу — и малому, и большому.
Description : Коллекция эссе Сьюзен Сонтаг «О фотографии» впервые увидела свет в виде серии очерков, опубликованных в New York Review of Books между 1973 и 1977 годами. В книге, сделавшей ее знаменитой, Сонтаг приходит к выводу, что широкое распространение фотографии приводит к установлению между человеком и миром отношений «хронического вуайеризма», в результате чего все происходящее начинает располагаться на одном уровне и приобретает одинаковый смысл. Главный парадокс фотографии заключается, согласно Сонтаг, в том, что человек, который снимает, не может вмешаться в происходящее, и, наоборот, – если он участвует в событии, то оказывается уже не в состоянии зафиксировать его в виде фотоизображения.
