Requirements Engineering in IT-Projekten. Eignen sich klassische oder agile Methoden besser für das Anforderungsmanagement?
Requirements Engineering ist inzwischen ein wichtiger Bestandteil erfolgreicher IT-Projekte. Dabei geht es darum, die Bedürfnisse der Kunden in Bezug auf die Implementierung von Systemen so gut wie möglich zu erfüllen. Um Budget- und Zeitpläne einzuhalten, ist ein gutes Anforderungsmanagement unerlässlich.Doch welche Herangehensweise wird diesem Anspruch besser gerecht: klassisch oder agil? Oder eignen sich vielleicht eher hybride Methoden für das Requirements Engineering? Simone Weidenfelder erklärt, welche Vorgehensweise zur Ermittlung von Anforderungen am effizientesten ist, um eine hohe Qualität der Requirements zu gewährleisten.Dazu analysiert sie traditionelle Methoden wie das Wasserfall- oder das V-Modell, aber auch agile Methoden wie Scrum. Sie stellt die Vor- und Nachteile der jeweiligen Herangehensweisen vor, wobei sie in erster Linie auf die praktische Anwendbarkeit achtet. Abschließend gibt sie Handlungsempfehlungen für die Organisation von IT-Projekten.Aus dem Inhalt:- Agilität;- ISO/IEC 12207;- RUP;- Rational Unified Process;- Design Thinking;- Lean Management

Human Compatible
Künstliche Intelligenz und wie der Mensch die Kontrolle über superintelligente Maschinen behält »Das bedeutendste Buch über KI in diesem Jahr.«- The Guardian, 24.09.2019Werden Maschinen bald auf nahezu allen Gebieten intelligenter sein als der Mensch? Auch wenn das vielversprechend klingt, ist die Entwicklung einer Superintelligenz zugleich ein ernstzunehmendes Risiko. Denn ist diese einmal da, können wir nicht mehr einfach den Stecker ziehen. Niemand kann die Chancen und Risiken der künstlichen Intelligenz besser beurteilen als Stuart Russell, der seit mehr als einer Dekade an vorderster Front der KI-Forschung arbeitet. Er veranschaulicht mit brillanten Analogien, wie sich natürliche und künstliche Intelligenz voneinander unterscheiden, und macht deutlich, weshalb wir vermeiden müssen, dass die Maschinen für uns unkontrollierbar werden. Fundiert, eindringlich und visionär zeigt Human Compatible neue Perspektiven und Lösungswege für die KI-Forschung auf, um zu gewährleisten, dass superintelligente Maschinen unsere Ziele verfolgen und nicht ihre eigenen.

The Internet of Things (IoT) is becoming a major application area for embedded systems. As a result, more and more people are becoming interested in learning about embedded design and programming. Technical colleges and universities are moving away from legacy 8 and 16-bit microcontrollers and are introducing 32-bit embedded microcontrollers to their curriculums. Many IoT applications demand precision, high processing power, and low power consumption.Produced by IBM, Node-RED is an open-source visual editor for wiring the Internet of Things. Node-RED comes with a large number of nodes to handle a multitude of tasks. The required nodes are selected and joined together to perform a particular task. Node-RED is based on flow type programming where nodes are configured and joined together to form an application program. There are nodes for performing complex tasks, including web access, Twitter, E-mail, HTTP, Bluetooth, MQTT, controlling GPIO ports, etc. One particularly nice aspect of Node-RED is that the programmer does not need to learn how to write complex programs. For example, an email can be sent by simply joining nodes together and writing only a few lines of code.The aim of this book is to teach how Node-RED can be used in projects. The main hardware platform used with most of the projects in this book is Raspberry Pi 4. Chapters are included to show how Node-RED can be also be used with Arduino Uno, ESP32 DevKitC, and the ESP8266 NodeMCU microcontroller development boards.Prof. Dr. Dogan Ibrahim is a Fellow of the Institution of Electrical Engineers. He is the author of over 60 technical books, published by publishers including Wiley, Butterworth, and Newnes. He is the author of over 250 technical papers, published in journals, and presented in seminars and conferences.
