Top-down and bottom-up approaches are methods used to analyze and choose securities.

Top-Down vs. Bottom-Up: What's the Difference?

Top-down and bottom-up are both strategies of information processing and knowledge ordering, used in a variety of fields including software, humanistic and scientific theories see systemics , and management and organization. In practice, they can be seen as a style of thinking, teaching, or leadership. A top-down approach also known as stepwise design and stepwise refinement and in some cases used as a synonym of decomposition is essentially the breaking down of a system to gain insight into its compositional sub-systems in a reverse engineering fashion. In a top-down approach an overview of the system is formulated, specifying, but not detailing, any first-level subsystems. Each subsystem is then refined in yet greater detail, sometimes in many additional subsystem levels, until the entire specification is reduced to base elements.

The top-down and bottom-up approaches to deploying your identity management solution are provided to help you decide the best way to integrate identity management capabilities into your environment. Each approach has distinct advantages and disadvantages, as shown in Table High deployment coverage in early phases Earlier return on investment High visibility of organizational changes Higher impact to organization. Tactical, limited coverage Delayed return on investment Lower impact to overall organization Higher deployment costs. User and business awareness of the product.

Top-down and Bottom-up planning

Function point analysis is a widely cited method for estimating software project size, which is an important activity of project management. At the beginning stage of planning, the top-down approach can be applied. Having obtained more systems specifications at later stages, the bottom-up approach might also be used to improve the accuracy of the estimation. However, the bottom-up approach is not a conventional way of function point analysis. There was no empirical evidence showing the difference between the fully informed top-down approach and the bottom-up approach.

Когда ее глаза привыкли к темноте, Сьюзан разглядела, что единственным источником слабого света в шифровалке был открытый люк, из которого исходило заметное красноватое сияние ламп, находившихся в подсобном помещении далеко внизу. Она начала двигаться в направлении люка. В воздухе ощущался едва уловимый запах озона. Остановившись у края люка, Сьюзан посмотрела. Фреоновые вентиляторы с урчанием наполняли подсобку красным туманом.

 Давайте же, - скомандовал Фонтейн. Джабба нажал на клавишу. И в следующую секунду все присутствующие поняли, что это было ошибкой. ГЛАВА 119 - Червь набирает скорость! - крикнула Соши, склонившаяся у монитора в задней части комнаты.

Коммандер устало опустил глаза, затем поднял их вновь. - Сьюзан, выслушай меня, - сказал он, нежно ей улыбнувшись.  - Возможно, ты захочешь меня прервать, но все же выслушай до конца. Я читал электронную почту Танкадо уже в течение двух месяцев. Как ты легко можешь себе представить, я был шокирован, впервые наткнувшись на его письмо Северной Дакоте о не поддающемся взлому коде, именуемом Цифровая крепость.

    The algorithms are designed using two approaches that are the top-down and bottom-up approach.

    Planning is one of the most important aspects of a successful, enterprise-wide performance management process.

    In the top-down approach, design process starts with specifying the global system state and assuming that each component has global knowledge of the system.

    Bottom-up. Does a top-down approach bear more advantages than a bottom-up approach described, then the different methods of investigation are displayed and in the end the way the hypotheses are tested pdf. Netzwerk. (​.
