I imagined a neat and tidy software career

Variables Algorithms

Software is logical, and "compiles" Right or wrong answer a mathematically provable range of optimized solutions or at least Deterministic solution

The universe is a giant clock. The laws of nature act like gears and springs, causing everything to move in a predictable and orderly way. -- Issac Newton (Not exactly, but kinda the exact words)

My first real-​ life software project Fixed price software delivery in a consultant team Thorough requirement spec from client Client analysts answering our queries, mostly by email Software architecture blueprint upfront Waterfall - Project lead had regular checkin with client Great team - we delivered on time! Domain: insurance workflow

We applied design patterns

Single Responsibility Principle Open/Closed Principle Liskov Substitution Principle Interface Segregation Principle Dependency Inversion Principle Image Credit: Robert Ecker We applied SOLID principles

But, our software never made it to the users

The client's analysts misunderstood (and oversimplified) core user needs. We made the wrong interpretation of the client analysts' email response to our questions. The client's business sponsor didn't align with the parent company about starting the project. No one told us a mandatory frontend framework had to be used. Rewrite considered too costly. Project X dropped, shelved, and forgotten. We (the consultant team) got paid well. We got praised for on-​ time delivery. Lots of tech learning and experiences, so why are we not feeling happy? So what was the rub

Design cannot happen in a closed system My existential conundrum Long way from neat and tidy to useful software <> "giant clock"

Impactful software systems Req., code, test, deploy, run Scientific modeling Technical Complexity First cross over the bridge Software-​ Centric Craft

How do I increase my odds of understanding, and impacting the "larger" decisions around software? Architect Developer Career crossroad - context & systems awareness Software swims in a system of systems

Social Subsystem Concerned with social relations (teams, knowledge networks), reward systems, authority structures, behavioral patterns, culture. Whole Work (System of Systems) Technical Subsystem Concerned with physical systems (hardware, software, technology) as well as mechanisms (e.g. tasks and processes) to transform inputs to outputs. Joint Optimization External Subsystem Concerned with the outside environment (users, customers, partners, stakeholders, society) with which an organization interacts and seeks value exchange with through its product and services.

One biggest challenge in software development is communication issues between IT people and business people, and between IT people and managers. Software craft is a relational activity individual craft Collective craft -- Vladik Knononov

How is all this social buzz relevant for me as an engineer? Aren't all big companies in similar waters? I enjoy ranting about it at water coolers.

1994 intrinsic motivation

Human beings are motivated not by survival, but also by the aspirations to reach our full potential. Surrounded by complexity, we have directed our motivation toward "making things less bad" rather than "creating great things" we care deeply about.
