Book Review: The Essence of Software Engineering

Applying the SEMAT Kernel

I have had the opportunity to lead dozens of software development projects which I love doing. I have also had the opportunity to watch dozens of software development project from the sidelines, while working on my own project, or in place as a consultant to accomplish something other than run the development process.

From the sidelines I have seen some succeed, some crash and burn, and the rest get close enough to success that the team can sell it as a success. Sometimes the later takes a heck of a sales job. I would say in my book 80% of those sold as successes failed. They either came in well over budget, well beyond their projected delivery date, or delivered such buggy software that the maintenance effort was as big as the development effort. Success to the team simply meant they considered the project over. You will find of those project teams run as fast as they can instead of doing a retrospective study.

The hard and sad part of watching the projects flop is that they are so predictable. A lot of times I find an environment has just come to terms with the fact that all the projects will come in late, over budget, and buggy. They have accepted reaching the end of the project as the only measure of success. You will usually find those environments are running in fire mode. Meaning the highest priorities for the day are the hottest fires and there are fires for everyone every day. They can't see it, but even there larger strategic projects are reacting to fires. They never get ahead, they just keep slowly slipping further behind.

So by now you are probably wondering what all that blather has to do with this book? To be able to recognize a project that is going off-track takes years of experience. The SEMAT Kernel provides a set of tools that enable those, that would normally not have enough experience to recognize when the project is going off-track, to be able to. The book is broken down into seven parts. I have listed each part below with the chapters they contain.

Part I: The Kernel Idea Explained
1. A Glimpse of How the Kernel Can Be Used
2. A Little More Detail about the Kernel
3. A 10,000-Foot View of the Full Kernel
4. The Kernel Alphas Made Tangible with Cards
5. Providing More Details to the Kernel through Practices
6. What the Kernel Can Do for You

Part II: Using the Kernel to Run an Iteration
7. Running Iterations with the Kernel: Plan-Do-Check-Adapt
8. Planning an Iteration
9. Doing and Checking the Iteration
10. Adapting the Way of Working
11. Running an Iteration with Explicit Requirement Item States

Part III: Using the Kernel to Run a Software Endeavor
12. Running a Software Endeavor: From Idea to Production
13. Building the Business Case
14. Developing the System
15. Operating the Software

Part IV: Scaling Development with the Kernel
16. What Does It Mean to Scale?
17. Zooming In to Provide Details
18. Reaching Out to Different Kinds of Development
19. Scaling Up to Large and Complex Development

Part V: How the Kernel Changes the Way You Work with Methods
20. Thinking about Methods without Thinking about Methods
21. Agile Working with Methods

Part VI: What’s Really New Here?
22. Refounding Methods
23. Separation of Concerns Applied to Methods
24. The Key Differentiators

Part VII: Epilogue
25. This Is Not the End
26. ... But Perhaps It Is the End of the Beginning
27. When the Vision Comes True

Appendixes
Appendix A. Concepts and Notation
Appendix B. What Does This Book Cover with Respect to the Kernel?

This book is not about defining or executing a new software development process, so don't expect to find how to create user stories, manage a product backlog, implement an instance of the RUP, or document your software architecture. This book is about the essential elements that are part of every software development process and how to recognize their current state in order to understand where you are in the process of your choice. It also walks you through the process of assembling a method from activities you have selected to use.

The kernel is broken down into three areas of concern which include Customer, Solution, and Endeavor. Each area of concern encapsulates alphas (things that progress and evolve) and activities.

Alphas include Opportunity, Stakeholders, Requirements, Software System, Team, Work, and Way of Working. Each of these have six different states attached to them which reflect their maturity.

The book defines activity spaces as explore possibilities, understand stakeholder needs, ensure stakeholder satisfaction, use the system, understand the requirements, shape the system, implement the system, test the system, deploy the system, operate the system, prepare to do the work, coordinate activity, support the team, track progress, and stop the work.

The next step the book takes is to assemble the alphas and activities into practices. An example of a practice would be a requirements elicitation practice. The practices are then used to build methods.

One really nice thing this book does is provide a common vocabulary that can be use across processes. Meaning that no matter what process you are using the kernel's alphas and activities apply. This will make it easier to see the different processes for what they really are at their core and make them easier to understand.

One thing I would have like to see different with this book is the alphas full checklist be used instead of the short-form, or at least have the long form list included in an appendix. You can get the full checklist from the Essence – Kernel and Language for Software Engineering Methods which is on the SEMAT web site. This does not take anything away from the book, it is just a pet peeve of mine. I don't like when a book provides less detail than the free specifications available on line.

I have found some books that are just summaries of the online work and you end up being pointed to that work in every chapter. That is not the case with this book, there is a lot of information in this book you won't find in the specs on line. The format and writing style of the book also makes reading the book much more pleasurable than reading the Essence – Kernel and Language for Software Engineering Methods OMG submission.

Overall I found this book to be a breath of fresh air. It is hard to find any pure software engineering process books anymore. They all tend to be a rehash of all the latest agile processes out there, which are all just reworks of all the iterative processes out there. The book and its material is very usable. I highly recommend this book to anyone with any role in the software development field.

Contrary to mainstream media attention, the multiple possibilities of how consumer IoT will transform our everyday lives aren’t the only angle of this headline-gaining trend. There’s a huge opportunity for “industrial IoT” and “Smart Cities” to impact the world in the same capacity – especially during critical situations. For example, a community water dam that needs to release water can leverage embedded critical communications logic to alert the appropriate individuals, on the right device, as soon as they are needed to take action.
As more intelligent IoT applications shift into gear, they’re merging into the ever-increasing traffic flow of the Internet. It won’t be long before we experience bottlenecks, as IoT traffic peaks during rush hours. Organizations that are unprepared will find themselves by the side of the road unable to cross back into the fast lane. As billions of new devices begin to communicate and exchange data – will your infrastructure be scalable enough to handle this new interconnected world?
While many app developers are comfortable building apps for the smartphone, there is a whole new world out there.

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
The Internet of Things (IoT) is about the digitization of physical assets including sensors, devices, machines, gateways, and the network.
