Book Review: Mastering the Requirements Process

Getting Requirements Right

Today we have a lot of different software development processes to choose from. We have Scrum, XP, the Unified Process, the Rational Unified Process, the Open Unified Process, the Enterprise Unified Process, Lean Processes, DSDM, TDD, Cleanroom, RAD, Spiral, and Waterfall. I am sure there are plenty more. Those are just the ones I can think of sitting here waiting on the train.

All the different processes out there have one thing in common, not getting requirements right is their Achilles' heel. Wrong requirements mean a lot of rework at best, and complete project failure in the worst scenarios.

The Volere Requirement Process described in this book can be used with any of the processes listed above. Every process needs to gather requirements.

After starting with some fundamental truths about requirements gathering and an introduction to the Volere Requirement Process the author digs into the detail of the process's activities and resulting artifacts. I have listed the chapters below. The titles give you an idea of the variety of topics covered.

1. Some Fundamental Truths
2. The Requirements Process
3. Scoping the Business Problem
4. Business Use Cases
5. Investigating the Work
6. Scenarios
7. Understanding the Real Problem
8. Starting the Solution
9. Strategies for Today’s Business Analyst
10. Functional Requirements
11. Non-functional Requirements
12. Fit Criteria and Rationale
13. The Quality Gateway
14. Requirements and Iterative Development
15. Reusing Requirements
16. Communicating the Requirements
17. Requirements Completeness
A. Volere Requirements Specification Template
B. Stakeholder Management Templates
C. Function Point Counting: A Simplified Introduction
D. Volere Requirements Knowledge Model
Volere: Requirements Resources

The authors really give a lot of great advice on techniques for eliciting (they refer to it as trawling) requirements. They have outlined some great ways to interact with the project stakeholders that will get them thinking about the requirements that need to be met. It is clear the authors understand how difficult it can be working with stakeholders. The elicitation techniques account for stakeholders who have no idea what they are looking, to those that think they know what they want but need convinced otherwise, because they don't have a full picture of the context yet.

The attention given to non-functional requirements was great. I have seen some requirements books that mention them but stay within the context of functional requirements. This book has a full chapter on them and treats them throughout the rest of the book as first class citizens. The reason I mention this is, that as a software architect, the non-functional (quality attributes) are what I am interested in during the architecture phase.

One of the things I really like about the book is that it includes the entire Volere Requirements Specification in one the appendices. My one gripe with the book is that you have to pay $55 to download the electronic version of the template from the author's web site.

The authors do a really great job of covering the full requirements gathering process using a case study. They cover a ton of deliverables and they cover them in depth.

One of the other things I found really cool was the Requirements Knowledge Model. It shows the collected knowledge you gain throughout the requirements process It also provides a common language to use for managing and communicating requirements.

The reason I found this to be so cool is that the number one thing documenting a system does for me is give me the detailed knowledge I need to understand it. More problems are usually found trying to communicate a system to different stakeholders than are found just running it.

Overall I found this book easy to read and understand. The authors have a great writing style.

If you have anything to do with requirements, no matter the process, this book belongs on your shelf.

DevOpsSummit New York 2018, colocated with CloudEXPO | DXWorldEXPO New York 2018 will be held November 11-13, 2018, in New York City. Digital Transformation (DX) is a major focus with the introduction of DXWorldEXPO within the program. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term.

Consumer-driven contracts are an essential part of a mature microservice testing portfolio enabling independent service deployments. In this presentation we'll provide an overview of the tools, patterns and pain points we've seen when implementing contract testing in large development organizations.
Containers and Kubernetes allow for code portability across on-premise VMs, bare metal, or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this session we'll describe best practices for "configuration as code" in a Kubernetes environment. We will demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure ...

Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
Most DevOps journeys involve several phases of maturity. Research shows that the inflection point where organizations begin to see maximum value is when they implement tight integration deploying their code to their infrastructure. Success at this level is the last barrier to at-will deployment. Storage, for instance, is more capable than where we read and write data. In his session at @DevOpsSummit at 20th Cloud Expo, Josh Atwell, a Developer Advocate for NetApp, will discuss the role and value...
