SAP, The Agile Way
Praxisbewährte Tipps für die erfolgreiche agile Arbeit mit weltweit verteilten SAP-Teams.Der weltweit tätige SAP-Berater und Agile Coach Klaus Wybranietz zerlegt in diesem Buch das hartnäckige Vorurteil: »Ja, Scrum ist toll, aber mit SAP funktioniert das nicht.« Er beweist nämlich seit Jahren das Gegenteil: Scrum und SAP können auf einen Nenner gebracht werden – und das sogar sehr erfolgreich. Denn in seinen Projekten für internationale Großkonzerne hat Klaus Wybranietz immer wieder die Erfahrung gemacht: Selbst über den Globus verteilte SAP-Teams können mit Scrum in der halben Zeit dreimal so effektiv sein.In diesem Buch erklärt der Autor die Entwicklungsstufen, über die er SAP-Teams aus dem klassischen Wasserfalldenken heraus und stattdessen hinein in die agile Performance führt. Das fängt beim Teambuilding trotz Superstars an, führt über den Aufbau von gezielten Kompetenzen und hilfreichen Regelwerken bis hin zum Schaffen echter Kundenwerte durch die Anwendung von Kanban-Metriken. Das alles funktioniert seit vielen Jahren auch mit weltweit verteilten SAP-Teams – »Ja, aber …« hat als Argument somit ausgedient.AUS DEM INHALT //- SAP und Scrum – das geht doch nicht?- Die Grundlagen von Scrum- Mit verteilten SAP-Teams remote arbeiten- Mit agilen SAP-Teams starten- Skalierung mit dem Agile Working Model 4 SAP- Praktiken für fortgeschrittene agile SAP-Teams
Pro Cryptography and Cryptanalysis with C++20
Develop strong skills and a passion for writing cryptography algorithms and security schemes/modules using C++ 20 and its new features. You will find the right methods of writing advanced cryptographic algorithms (such as, elliptic curve cryptography algorithms, lattice-based cryptography, searchable encryption, and homomorphic encryption), examine internal cryptographic mechanisms, and discover common ways in which the algorithms could be implemented and used correctly in practice.The authors avoid the complexities of the mathematical background by explaining its mathematical basis in terms that a programmer can easily understand. They show how “bad” cryptography creeps in during implementation and what “good” cryptography should look like. They do so by showing and comparing the advantages and disadvantages based on processing time, execution time, and reliability.WHAT YOU WILL LEARN* Understand where and why cryptography is used and how it gets misused * Discover what modern cryptography algorithms and methods are used for * Design and implement advanced cryptographic mechanisms * See how C++20 and its new features are impacting the future of implementing cryptographic algorithms* Practice the basics of public key cryptography, including ECDSA signatures and more* Find out how most of the algorithms can be brokenWHO THIS BOOK IS FORProfessional programmers, developers, and software engineers who are developing cryptography algorithms and security schemes/modules in C++.

Requirements Engineering für Dummies
Für den Erfolg von Softwareprojekten ist es entscheidend, sich erstmal klar zu machen, wozu das System überhaupt dienen soll und wie es dafür beschaffen sein muss. Klingt eigentlich selbstverständlich, und doch scheitern Projekte oft gerade an der Anforderungsanalyse. Das Buch "Requirements Engineering für Dummies" beschreibt verständlich und pragmatisch, wie Sie vorgehen sollten - und zwar sowohl für klassische als auch für agile Projekte. Es liefert Ihnen Techniken, wie Sie Ziele bestimmen und Releases sinnvoll zusammenstellen, wie Sie Anforderungen erheben und verstehen, wie Sie mit Änderungen umgehen und wie Sie Fallstricke vermeiden. Das Buch ist auch geeignet zur Vorbereitung auf die CPRE-FL-Prüfung. Dr. Marcus Winteroll ist Mitglied der oose Innovative Informatik eG, einem Anbieter von Schulungen und Workshops zu Software & Systems Engineering in Hamburg. Als Trainer und Berater beschäftigt er sich mit der Analyse sowie Verbesserung von Geschäfts- und Entwicklungsprozessen. Dazu setzt er auf agile Methoden; aber auch die klassischen Vorgehensweisen sind ihm aus seiner langjährigen Erfahrung als Requirements Engineer, Projektleiter, Prozessmanager, Qualitätssicherer und Entwickler vertraut. Seine gesammelten Erfahrungen teilt er auf Konferenzen und als Autor von Fachartikeln.Über den Autor 13EINLEITUNG 25Über dieses Buch 25Konventionen in diesem Buch 26Was Sie nicht lesen müssen 26Törichte Annahmen über die Leser 26Wie dieses Buch aufgebaut ist 26Teil I: Requirements Engineering verstehen 27Teil II: Vorgehen im Requirements Engineering 27Teil III: Anforderungsanalyse 27Teil IV: Requirements Management 27Teil V: Der Top-Ten-Teil 27Symbole, die in diesem Buch verwendet werden 27Wie es weitergeht 28TEIL I: REQUIREMENTS ENGINEERING VERSTEHEN 29KAPITEL 1 DAS IST REQUIREMENTS ENGINEERING 31Warum uns Requirements Engineering weiterhelfen kann 31Aufgaben im Requirements Engineering 34Wer das Requirements Engineering macht 36Der Requirements Engineer 37Wer sonst noch das Requirements Engineering macht 37Viele Arten von Anforderungen 38Funktionale Anforderungen 38Nichtfunktionale Anforderungen 39Randbedingungen 40Abstraktionsstufen von Anforderungen 41Möglichkeiten der Zertifizierung 42Zertifikate des IREB 43Zertifikate des IIBA 44PMI Professional in Business Analysis (PMI-PBA) 45KAPITEL 2 EINBETTUNG DES REQUIREMENTS ENGINEERING47Das Zusammenspiel mit den übrigen Beteiligten 47Die Kunden des Requirements Engineering 48Wer sonst noch so wichtig ist: die Stakeholder 48Die Basis vieler Anforderungen: die Geschäftsprozesse 49Das Anforderungsdokument: eines für alle? 50Requirements Engineering im klassischen Vorgehen: alles klar 52Was zu erwarten ist 52Was nicht zu erwarten ist 52Requirements Engineering in agilen Projekten: just in time 53Beliebte Missverständnisse beim agilen Requirements Engineering 53Was agiles Vorgehen vom klassischen unterscheidet 54Klassisch, agil, Festpreis, Aufwandspreis –nicht jede Kombination ist sinnvoll 56Klassisch und Festpreis 56Agil und Aufwandspreis 56Agil und Festpreis 57Klassisch und Aufwandspreis 57Alles im Überblick 57KAPITEL 3 FALLSTRICKE59Was wir von den Kunden erwarten dürfen – und sie von uns 59Wer nimmt die Anforderungen auf? 60Der Projektleiter als Requirements Engineer 60Der Product Owner als Requirements Engineer 61Entwickler als Requirements Engineers 61Kunde und Nutzer als Requirements Engineers 62Die richtige Detaillierung von Anforderung 63Umgang mit Änderungen 64Dokumentation von Anforderungen 66TEIL II: VORGEHEN IM REQUIREMENTS ENGINEERING 69KAPITEL 4 VORGEHEN IN KLASSISCHEN PROJEKTEN71Einordnung in den Projektablauf 71Der Ablauf 73KAPITEL 5 VORGEHEN IN AGILEN PROJEKTEN77Direkte Kommunikation statt Dokumentation 78Der Wert gibt den Takt an 79Das Ziel immer vor Augen 80Die Vorbereitungsphase 80Requirements Engineering in Scrum 82Scrum kurz erklärt 82Wo das Requirements Engineering in Scrum stattfindet 84Das Product Backlog weiterentwickeln: Refinement 86Fertig heißt fertig: die Definition of Done 88Welche Rolle für die Anforderungen zuständig ist 89Wenn mehrere Teams an einem System arbeiten 90Fortwährende Analyse statt Änderungsmanagement 91Die Unterschiede zwischen klassischem und agilem Requirements Engineering 92KAPITEL 6 ANPASSUNG DES REQUIREMENTS-ENGINEERING-PROZESSES93Einflussfaktoren 93Facetten des Requirements-Engineering-Prozesses 94Zeitfacette 95Zweckfacette 96Zielfacette 96Konfiguration des Prozesses 97TEIL III: ANFORDERUNGSANALYSE 99KAPITEL 7 AN DIE ANFORDERUNGEN HERANKOMMEN101Stakeholderanalyse 102Stakeholder identifizieren 103Stakeholder verstehen 105Maßnahmen zur Einbindung der Stakeholder 110Zusätzliche Anforderungsquellen 111Anforderungen ermitteln 112Von geheimen und selbstverständlichen Anforderungen: das Kano-Modell 113Wer fragt, gewinnt: die Befragungstechniken 115Anforderungen gemeinsam erheben: Kooperationstechniken 121Schauen Sie genau hin: Beobachtungstechniken 123Systemarchäologie und der Blick zurück: artefaktbasierte Techniken 126Recycling im Requirements Engineering: die Wiederverwendung von Anforderungen 127Seien Sie kreativ: Entwurfs- und Ideenfindungstechniken 128Hypothesen bilden und ausprobieren 133Techniken, die Sie zusätzlich unterstützen 134Welche Technik Ihnen weiterhilft 135Konflikte und der Umgang damit 138Analyse von Konflikten 138Auflösung von Konflikten 139KAPITEL 8 WAS UNS ZU BEGINN KLAR SEIN SOLLTE 145Wohin soll die Reise gehen?
