Process improvement too often reflects a significant disconnect between theory and practice. Making Process Improvement Work for Service Organizations bridges the gap–offering a straightforward, systematic approach to planning, implementing, and monitoring a process improvement program. Managers and practitioners will appreciate the book’s concise presentation style and will be able to apply its practical ideas immediately to real-life challenges.

With examples based on the authors’ own extensive experience, this book shows how to define goals that directly address the needs of your organization, use improvement models appropriately, and devise a pragmatic action plan. In addition, it reveals valuable strategies for deploying organizational change, and delineates essential metrics for tracking your progress. Appendices provide examples of an action plan, a risk management plan, and a mini-assessment process.

You will learn how to

Scope and develop an improvement plan Identify and prioritize risks and mitigate anticipated difficulties Derive metrics that accurately measure progress toward business goals Sell your improvement program in house Initially target practitioners and teams most open to new approaches and techniques Stay focused on goals and problems Align the actions of managers and practitioners Delay major policy documents and edicts until solutions have been practiced and tested Use existing resources to speed deployment

Incorporate improvement models, such as SEI CMMISM for Services, into your improvement program

For those managers who are tired of chronic problems during service creation and delivery, constant new improvement schemes, and a lack of real progress, this easily digestible volume provides the real-world wisdom you need to realize positive change in your organization.

Harness the power of DevOps to boost your skill set and make your IT organization perform betterAbout This BookGet to know the background of DevOps so you understand the collaboration between different aspects of an IT organization and a software developerImprove your organization's performance to ensure smooth production of software and servicesDeploy top-quality software and ensure software maintenance and release management with this practical guideWho This Book Is For

This book is aimed at developers and system administrators who wish to take on larger responsibilities and understand how the infrastructure that builds today's enterprises works. This book is also great for operations personnel who would like to better support developers. You do not need to have any previous knowledge of DevOps.

What You Will LearnAppreciate the merits of DevOps and continuous delivery and see how DevOps supports the agile processUnderstand how all the systems fit together to form a larger wholeSet up and familiarize yourself with all the tools you need to be efficient with DevOpsDesign an application that is suitable for continuous deployment systems with Devops in mindStore and manage your code effectively using different options such as Git, Gerrit, and GitlabConfigure a job to build a sample CRUD applicationTest the code using automated regression testing with Jenkins SeleniumDeploy your code using tools such as Puppet, Ansible, Palletops, Chef, and VagrantMonitor the health of your code with Nagios, Munin, and GraphiteExplore the workings of Trac—a tool used for issue trackingIn Detail

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all the flows from code through testing environments to production environments. It stresses the cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations.

After a quick refresher to DevOps and continuous delivery, we quickly move on to looking at how DevOps affects architecture. You'll create a sample enterprise Java application that you'll continue to work with through the remaining chapters. Following this, we explore various code storage and build server options. You will then learn how to perform code testing with a few tools and deploy your test successfully. Next, you will learn how to monitor code for any anomalies and make sure it's running properly. Finally, you will discover how to handle logs and keep track of the issues that affect processes

Style and approach

This book is primarily a technical guide to DevOps with practical examples suitable for people who like to learn by implementing concrete working code. It starts out with background information and gradually delves deeper into technical subjects.

Achieve improved network programmability and automation by leveraging powerful network programming concepts, algorithms, and toolsKey FeaturesDeal with remote network servers using SSH, FTP, SNMP and LDAP protocols.Design multi threaded and event-driven architectures for asynchronous servers programming.Leverage your Python programming skills to build powerful network applicationsBook Description

Network programming has always been a demanding task. With full-featured and well-documented libraries all the way up the stack, Python makes network programming the enjoyable experience it should be.

Starting with a walk through of today's major networking protocols, through this book, you'll learn how to employ Python for network programming, how to request and retrieve web resources, and how to extract data in major formats over the web. You will utilize Python for emailing using different protocols, and you'll interact with remote systems and IP and DNS networking. You will cover the connection of networking devices and configuration using Python 3.7, along with cloud-based network management tasks using Python.

As the book progresses, socket programming will be covered, followed by how to design servers, and the pros and cons of multithreaded and event-driven architectures. You'll develop practical clientside applications, including web API clients, email clients, SSH, and FTP. These applications will also be implemented through existing web application frameworks.

What you will learnExecute Python modules on networking toolsAutomate tasks regarding the analysis and extraction of information from a networkGet to grips with asynchronous programming modules available in PythonGet to grips with IP address manipulation modules using Python programmingUnderstand the main frameworks available in Python that are focused on web applicationManipulate IP addresses and perform CIDR calculationsWho this book is for

If you're a Python developer or a system administrator with Python experience and you're looking to take your first steps in network programming, then this book is for you. If you're a network engineer or a network professional aiming to be more productive and efficient in networking programmability and automation then this book would serve as a useful resource. Basic knowledge of Python is assumed.

This is a practical guide for software developers, and different than other software architecture books. Here's why:

It teaches risk-driven architecting. There is no need for meticulous designs when risks are small, nor any excuse for sloppy designs when risks threaten your success. This book describes a way to do just enough architecture. It avoids the one-size-fits-all process tar pit with advice on how to tune your design effort based on the risks you face.

It democratizes architecture. This book seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties.

It cultivates declarative knowledge. There is a difference between being able to hit a ball and knowing why you are able to hit it, what psychologists refer to as procedural knowledge versus declarative knowledge. This book will make you more aware of what you have been doing and provide names for the concepts.

It emphasizes the engineering. This book focuses on the technical parts of software development and what developers do to ensure the system works not job titles or processes. It shows you how to build models and analyze architectures so that you can make principled design tradeoffs. It describes the techniques software designers use to reason about medium to large sized problems and points out where you can learn specialized techniques in more detail.

It provides practical advice. Software design decisions influence the architecture and vice versa. The approach in this book embraces drill-down/pop-up behavior by describing models that have various levels of abstraction, from architecture to data structure design.
