The book is a complete manual for all critical situations a project manager might need to handle along the project¿s lifecycle. Written by a project manager with many years of experience, each chapter contains real-life examples with analysis and guidelines. Yoüll benefit from the down-to-earth knowledge that usually project managers learn over the course of years in critical and stressful situations with no preparation beforehand. It¿s not about academic methodologies ¿ it¿s about pragmatic solutions that work in real-life. Far too often, the wise theory of IT project management has nothing to do with reality. Managing IT Projects is your special compendium of knowledge, featuring "project management black magic,¿ chock full of proven recipes for project managers and IT organization managers, as well as advice on how to act in critical situations.What You'll LearnExamine the main reasons for delays in projects and see where they come from Review the key success factors in managing projects beyond project management methodologies and techniquesUnderstand the critical moments of projects and see how to prepare for themApply a pragmatic strategy and philosophy for successful project delivery and cooperation with customersWho This Book Is ForSoftware developers, project managers, engineering managers and software development directors, sales reps, executive and founders

Learn to write better automated tests that will dramatically increase your productivity and have fun while doing so. This book is a build-your-own adventure designed for individual reading and for collaborative workshops. You will build an xUnit automated test framework using JavaScript: initially a clone of Jest, but adding a couple of neat features borrowed from RSpec, the genre-defining tool for behavior-driven development (BDD). Along the way, you will explore the philosophy behind automated testing best practices. The automated test runner is one of the most important innovations within software engineering. But for many programmers, automated testing remains a mystery, and knowing how to write good tests is akin to sorcery.As the chapters of this book unfold, you will see how the humble test runner is an elegant and simple piece of software. Each chapter picks a single feature to build, like the "it" function or the "beforeEach" block. It picks apart the theory of why the feature needs to exist, and how to use it effectively in your own test suites. Every chapter ends with a set of ideas for extension points should you wish to explore further, alone or in groups. The book culminates in an implementation of test doubles and mocks¿one of the most difficult and misunderstood concepts within automated testing.By the end of the book, you will have gained a solid understanding of automated testing principles that you can immediately apply to your work projects. What You'll LearnBuild an xUnit automated test frameworkSee how an automated test runner worksUnderstand the best practices for automated unit testingEffectively use test doubles and mocksWho This Book Is ForSoftware developers with JavaScript experience who are seeking to master the art of automated testing.

Every day, successful software projects scale and sustain businesses of all sizes and across all industries. Unfortunately, the reality is that many software projects still fail. The reasons behind these failures are seldom due to the underlying technology. Misunderstandings and communication barriers lead to wrong decisions, missed opportunities, communication breakdowns, or worse¿huge economic loss.In this digitally connected world, business professionals can¿t afford to be hands-off on technical projects, but they also can¿t be expected to have technical certifications. They have first-hand knowledge of the business processes, are subject matter experts in software requirements, and they finance the projects. Even C-level management or board members need to rapidly gain just enough understanding of technology to make mission-critical decisions for businesses to survive and flourish. In most software projects the number of non-technical stakeholders far exceeds the numberof techies.This book distills the world of software projects into simple terms and relatable metaphors for even the most technically adverse reader. Real-life examples, entertaining analogies, and hand-drawn illustrations will stick with readers throughout their own software projects, bolstering their success. Business requirements, use cases, process flows¿the list goes on. It¿s all broken down in this game-changing book aimed at delivering for business and tech teams what DevOps has done for developers and operations.What You Will LearnKnow the importance of good business requirements and how to write themIdentify the most important business roles, key decisions, and critical activities involved in software projectsStrengthen collaboration between non-technical and technical teamsGrasp common software project terminology, required for non-techies Understand the software development life cycleGain insight on the common software project methodologies and how they differUnderstand what software developers do at a high levelWho This Book Is ForNon-technical business professionals (such as small business owners, startup founders, or employees of a business of any size or industry) who need to secure and implement a software solution. The reader may supervise or collaborate with technical teams, and may be a (beginning) software developer looking for practical insights and better ways to communicate with business colleagues.

Interested in giving Microsoft¿s new Multi-platform App UI (MAUI) a try? This book provides developers with a comprehensive set of tools and hands-on coding to build their own cross-platform applications.The book is a comprehensive end-to-end guide on creating, building, and distributing .NET MAUI applications. As you walk through each new concept, .NET MAUI expert and Microsoft MVP Shaun Lawrence will show the concept's value and uses, and then have you apply it in a build-along application. You will work with this build-along application right up until you are ready to ship it to the relevant stores (e.g., App Store, etc.).The underlying theme through the book is to explain a key concept, show how to implement it directly in order to reinforce your understanding, and then show potential simplifications (e.g., alternative libraries) that can help you reduce the complexities of an applications code base. What You Will LearnCreate a .NET MAUI applicationApply commonly required techniquesApply more advanced techniques to make applications stand outKnow what to consider when distributing applications to the relevant storesTake an application from concept through to productionWho This Book Is ForDevelopers who are new to .NET MAUI and cross-platform development. A basic knowledge of C# is required, but no prior knowledge using .NET MAUI is required. Experienced developers also will find the book useful as it covers topics key to modern day development (such as accessibility, performance, and distribution). Xamarin Forms developers will find the book useful as key features new to .NET MAUI that will aid in the migration from Xamarin Forms to .NET MAUI are explained.

Take a deep dive into the Azure SQL Database Hyperscale Service Tier and discover a new form of cloud architecture from Microsoft that supports massive databases. The new horizontally scalable architecture, formerly code-named Socrates, allows you to decouple compute nodes from storage layers. This radically different approach dramatically increases the scalability of the service. This book shows you how to leverage Hyperscale to provide next-level scalability, high throughput, and fast performance from large databases in your environment.The book begins by showing how Hyperscale helps you eliminate many of the problems of traditional high-availability and disaster recovery architecture. Yoüll learn how Hyperscale overcomes storage capacity limitations and issues with scale-up times and costs. With Hyperscale, your costs do not increase linearly with database size and you can manage more data than ever at a lower cost.The book teaches you how todeploy, configure, and monitor an Azure SQL Hyperscale database in a production environment.

Use continuous Integration (CI) and continuous delivery (CD) to improve the speed of software delivery. This book presents a game changer¿how to use pipelines to automate the software delivery process. The theories about CI/CD are much the same, but the book covers what the development of pipelines looks like and how testing of pipelines themselves should be performed.Most teams just plunge into coding, without thinking about the CI/CD process itself. Why don¿t we use the same development method for pipelines that we use for apps? Pipelines code development undergoes similar stages as application code development, such as requirements analysis, development, testing, implementation, operations, and monitoring. This is the starting point of the book. It describes the current challenges with pipeline development and how this process can be improved and structured. It describes in detail how to design pipelines and shows examples in BPMN 2.0 notation.What Yoüll LearnKnow the shortcomings and challenges of current pipeline development such as misalignment between the pipeline engineer and the team¿s workflow, the use of infrastructure as code (IaC), and pipeline securityUnderstand the need for CI/CD requirements through the book's non-exhaustive list of more than 60 CI/CD requirements provided to inspire and increase awarenessSee how certain choices affect the way a pipeline is designed (and realized)Become familiar with branching strategy, build strategy, test strategy, release strategy, and deployment strategy that are explained in detail in the book, including their effect on pipeline designKnow how pipelines can be unit tested, using a real-world exampleKnow how performance bottlenecks in a pipeline occur, how they can be detected, and how they can be solvedView a complete implementation, including code, showing how the guidelines in this book are applied to a real use caseWho This Book Is ForDevOps engineers and solution architects involved with automating the software supply chain and using application lifecycle management (ALM)/integration platforms such as Jenkins, CircleCI, Bamboo, and Azure DevOps; intermediate and experienced DevOps engineers (developers, ops engineers, test engineers); and ICT managers interested in the CI/CD pipeline development domain
