But the principles and practices of software architecting–what the authors call the “science of hard decisions”–have been evolving for cloud, mobile, and other shifts. Now fully revised and updated, this book shares the knowledge and real-world perspectives that enable you to design for success–and deliver more successful solutions. In this fully updated Second Edition, you will: Learn how only a deep understanding of domain can lead to appropriate architecture Examine domain-driven design in both theory and implementation Shift your approach to code first, model later–including multilayer architecture Capture the benefits of prioritizing software maintainability See how readability, testability, and extensibility lead to code quality Take a user experience (UX) first approach, rather than designing for data Review patterns for organizing business logic Use event sourcing and CQRS together to model complex business domains more effectively Delve inside the persistence layer, including patterns and implementation.

    This book serves as the first guide to focus on combining the benefits of balanced scorecards, operational dashboards, performance managements, and data visualization and then implement them in Microsoft Excel.

    It describes the Disciplined Agile Delivery (DAD) process decision framework and then works through a case study describing a typical agile team’s experiences adopting a disciplined agile approach. The book describes how the team develops the first release of a mission-critical application while working in a legacy enterprise environment. It describes their experiences from beginning-to-end, starting with their initial team initiation efforts through construction and finally to deploying the solution into production. It also describes how the team stays together for future releases, overviewing their process improvement efforts from their Scrum-based beginnings through to a lean continuous delivery approach that fits in with their organization’s evolving DevOps strategy. The DAD framework is a hybrid of existing methods such as Scrum, Kanban, Agile Modeling, SAFe, Extreme Programming, Agile Data, Unified Process and many others. DAD provides the flexibility to use various approaches and plugs the gaps not addressed by mainstream agile methods. In a nutshell, DAD is “pragmatic agile.” DAD describes proven strategies to adapt and scale your agile initiatives to suit the unique realities of your enterprise without having to figure it all out by yourself. Here’s an overview of what each chapter covers: * Chapter 1: Introduction. This chapter provides a quick overview of the book and a brief history of Disciplined Agile. * Chapter 2: Reality over Rhetoric. This chapter explores several common myths about DAD and more importantly disproves them. * Chapter 3: Disciplined Agile Delivery in a Nutshell. This chapter provides a brief yet comprehensive overview of the DAD framework. * Chapter 4: Introduction to the Case Study. This chapter introduces us to the team, describes the market opportunity that they hope to address, and describes the environment in which they’re working. * Chapter 5: Inception. The team’s initiation effort includes initial requirements modeling and planning with their stakeholders in a streamlined manner, initial architecture modeling, setting up their physical work environment, setting up the start of their tooling infrastructure, initial risk identification, and finally securing stakeholder support and funding for the rest of the first release. * Chapters 6 through 10: Construction. These chapters each describe a single Construction iteration, sharing the team’s experiences during each of those two-week timeboxes. * Chapter 11: Transition. The two-week transition phase focuses on final testing and fixing, training the support/help-desk staff, finishing a few short end-user “how to” videos, and deploying the solution into production. * Chapter 12: Future Releases. This chapter overviews the team’s improvement efforts over the next few releases, describing how they evolve from the agile Scrum-based lifecycle to a leaner approach and eventually to continuous delivery. * Chapter 13: Closing Thoughts. This chapter overviews the disciplined agile resources that are available to you. * Appendix: The Disciplined Agile IT Department. This short appendix overviews our ongoing work on the Disciplined Agile framework to address the full scope of an IT department. At 102 pages, you should find this book to be a quick, informative read.

    Many of today’s jobs require that you be familiar with Microsoft Excel. How can you become proficient at Excel when companies aren’t willing to teach you this valuable skill? This leaves many people trying to learn as they go and never quite feeling 100% comfortable with the program. What’s worse, most people haven’t even scratched the surface of Excel’s potential, even if they’ve been using it for years. If you feel this way, you’re not alone. Think about this for a second; what will your career look like in a year if you don’t take action today and improve your Excel skills? How about five years from now? Unless you take matters into your own hands things may not look much different. According to a recent Wall Street Journal article, people who show proficiency in Microsoft Excel and other common office applications earn, on average, 13% more than those who don’t. For most people this could mean tens of thousands of dollars over just a few years, and this doesn’t even factor in lost promotions and job offers. Can you afford to leave so much on the table as a result of maintaining the status quo? I’ve experienced this transformation in my career and can tell you first hand how it has helped me. When I was fresh out of college and working my first accounting job my manager asked me to complete a project that involved using VLOOKUPS. I enthusiastically obliged, walked back to my desk, and proceeded to panic. I tricked myself into thinking that I was an excel expert only because I knew a few formulas, my limited knowledge only scratched the surface. I turned to a college buddy for help; Google. I eventually managed to learn what I needed, after a lot of time and energy. I’ve climbed the ladder and worn many hats since then. I can’t say that the opportunities I’ve earned in my career are solely due to my increasing Excel proficiency. What I can definitely say is that Excel has earned me more opportunities to prove myself to management than waiting for opportunities to materialize on their own. That’s why I decided to write this book. My goal is to take you from Excel novice to master in the shortest time possible. I wrote my book specifically for the busy professional, in an easy to read manner that gets straight to the point and teaches the meat of Excel. I wrote this book for you. Don’t take my word for it: "I think the writing style is helpful for readers to engage. I like that as I read the book, I felt as if I was in front of someone who was actually teaching me. I also liked the fact that the book is written in a laid back manner. I mean Excel is difficult as it is, why would you want to make it worst by adding some weird terminology to the book? Its plain, simple and easy to follow." -Eliana Pereira, Accountant I have helped many people improve their careers through Excel and now it’s your turn. Here is what you get when you download my book: -18 chapters of the most useful Excel techniques that will immediately take your skills to the next level -Practical use cases plus downloadable workbooks so that you can take what you learn and feel, first hand, how to apply those skills to real world scenarios -A FREE copy of my latest book on Google Sheets so you can stay ahead of the curve You’re at the point of decision.
