The Data Ops Manifesto
“Individuals and interactions over processes and tools”
Processes and tools are the foundation of effective analytics, and I don’t think that’s what the authors meant by their use of the word “over”. Yes, of course, individuals and interactions inform the design of such processes and tools, but the former are transient. People come and go. Interactions wax and wane.
This value hints at a certain charm around informality, but often an apparent lack of structure means only that the structure is unknown or perhaps denied. Analytics need structure if they are to track how structure (schema) evolves.
“Working analytics over comprehensive documentation”
Analytics need to work. However, ancillary support like documentation is the foundation for answering new questions , questions not addressed by what’s merely at work right now.
Consider the division of database systems into online transaction processing (OLTP) and online analytical processing (OLAP). OLTP systems are the working systems, made to handle specific questions (requests, transactions) quickly. OLAP systems, though also tuned to handle specific aggregation-hungry questions, are there to answer new questions.
To emphasize a “working” system over support for infrequently-asked questions is to devalue the OLTP/OLAP distinction.
“Customer collaboration over contract negotiation”
My disagreement with this relates to my take on the importance of processes and tools above. Collaboration how? What does it look like? Contracts materialize collaboration. In software development, they often take names like interfaces, types, unit tests, etc.
“Experimentation, iteration, and feedback over extensive upfront design”
What is the thing with which you can experiment, iterate, and obtain feedback? An upfront design. At first I thought I would need to call out “extensive” as a strawman, but I realize it’s actually great for me here.
Extent is the area covered by something. An extensive design covers what you know there is to cover. What if you know very little about the problem area upfront? Well then, your extensive design shouldn’t take very long, and it will grow in extent as you experiment, iterate, and get feedback. But materialize what you (claim to) know up front.
“Cross-functional ownership of operations over siloed responsibilities”
Cross-functional use of resources is great, but I turn to the single-responsibility principle when it comes to ownership, to responsibility. This dichotomy is analogous to the second part of the SOLID acronym for software design principles, namely the open-closed principle, where an entity allows its behavior to be extended without allowing its modification.
