What Are Some Weaknesses of a Liberal Arts Education

Key Takeaways

• The power to effectively analyze a problem, evaluate dissimilar options, and engineer a solution requires the skills taught in the liberal arts.
• Many problems with software projects are acquired by poor communication. Studying effective linguistic communication and advice tin lead to more successful software.
• Great communicators always remember the importance of context–know your audience. This applies equally to discussions of requirements and to designing interfaces between microservices.
• The best engineers blend a noesis of information science with practiced critical thinking and problem solving.
• The liberal arts teaches the skills necessary to be a lifelong learner, which is vital to keep upwardly with the ever-changing world of software.

The pedagogy of most software engineers involves a heavy focus on STEM subjects: science, technology, applied science, and math. Other subjects, specially those nether the umbrella of liberal arts, are ofttimes thought of as less of import, or simply an annoying requirement to graduate. However, much of what helps you become a great software engineer, and create outstanding software that people want to employ, comes from outside the world of Stem. This might sound similar great advice to give to a freshman computer scientific discipline student, but it's equally helpful for the 20-year software veteran.

Computer scientific discipline is the report of algorithms, information structures, and operating systems. Programming is the practical implementation of computer science. Software engineering is the employ of software to solve problems. The ability to effectively clarify a problem, evaluate different options, and engineer a solution requires the skills taught in the liberal arts.

What Does "Liberal Arts" Mean?

I recall it's important to kickoff analyze what is meant by the terms liberal arts or a liberal arts education. A pithy, merely not very useful, definition could exist anything that isn't STEM. While technically truthful, information technology doesn't actually tell us the benefits or expected outcomes from studying the humanities and social sciences. Clearly, if you go a degree in biology, you will probably be qualified to be a biologist. But the purpose of the liberal arts isn't to train directly for a specific profession.

Liberal is sometimes, incorrectly, assumed to simply mean the opposite of conservative, every bit in politics. Rather, information technology shares a root with liberated, meaning free, in contrast to imprisoned or subjugated. A liberal pedagogy provides the skills necessary to function successfully equally costless citizens in society. According to Syracuse Academy's Gerald Greenberg, "It teaches them [students] how to think critically, communicate clearly, analyze and solve complex problems, appreciate others, understand the physical globe, and be prepared to learn continuously so they can work with others and on their ain to meet the challenges of the future."

Software engineers are expected to think critically and analyze and solve complex problems. Greenberg's other lessons (clear communication, appreciating others, and continuous learning) may seem less important for software development, but those skills are what make the divergence betwixt but a skillful developer and a slap-up software engineer.

The Importance of Language

When the musical Hamilton came to boondocks, I noticed my co-workers were divided into two groups: Those trying desperately to get tickets, and those with no interest in seeing the show. 1 of the latter said he didn't similar musicals because they were unrealistic–in real life, people don't spontaneously break into song and trip the light fantastic. While that is true, the purpose of a musical or play isn't to be 100% realistic; it's to tell a story, convey emotion, and make the audience call back, all in a express corporeality of fourth dimension. Songs incorporate music and rhythm to take hold of the audience more intensely than simply spoken words. The bandwidth of the theatre is constrained, and music is the data compression applied science.

A similar comment that "people don't really talk (or sing) like that" could exist fabricated virtually software lawmaking. When creating instructions for the computer, at that place are severe constraints on the syntax. That makes lawmaking closer to poetry than prose. I don't expect software engineers to get-go describing themselves as code poets, only they conspicuously are writers. And every writer must know their audience.

Know Your Audience

If at that place is 1 bulletin to exist remembered from English Limerick 101, it is "know your audience." When teaching students how to be amend writers, one of the first steps is acknowledging and agreement who you are writing for. The style used for a children's volume is vastly different from a college thesis, and as well varies between a history of the Roman empire ora lab study for biological science.

In her presentation on readable lawmaking, Laura Savino pointed out that programmers are writing for two audiences: the compiler and other developers. 1 of these is very opinionated, and will tell us loudly when it doesn't understand. That skews a lot of lawmaking to favor the compiler equally the master audience. However, since humans must maintain the code, it's vital that it remain readable for the audition between the keyboard and chair.

The thought of ubiquitous language, from Domain-Driven Design, aids in communication by clearly defining terms as they apply within a specific context. In such a situation, constraints liberate – past focusing on a small audience, you are better able to limited your intent. The words and phrases in your ubiquitous linguistic communication may accept a different pregnant outside your context, but that concern goes away considering your audition is not everyone.

At the code level, DDD recommends the utilize of value types over native data types. Passing around an AccountNumber carries more than meaning than passing a elementary cord or integer. The rules for checking if an AccountNumber is valid tin be clearly defined, and invalid values could be prevented from being constructed. Once nosotros have agreed on a ubiquitous language, it can be used to forbid many mutual errors that could arise from unclear communication.

Every Trouble is a Communication Problem

Whether providing requirements from customers to engineers ("I'm a people person!") or sending requests to an API, advice is present throughout the application lifecycle, and at every layer of a software system. When something doesn't go every bit planned, the solution normally starts with improving the communication.

Waterfall projects are based on discrete, meaning points of communication. The requirements are gathered, written upwardly, and handed to the developers. The developers write the lawmaking and paw it to QA to exam. If the software doesn't meet expectations, everyone starts pointing fingers and assigning blame. An active approach hopes to solve that by creating more frequent, smaller points of advice. This makes it easier for everyone to sympathize what is being discussed, identify any issues, and fix them before they become major obstacles.

In an n-tier, monolithic codebase, yous have a limited number of communication points. (The front-end talks to the back-end. The back-end talks to the database.) Within any single layer you don't think much about the communication path because you're making direct function calls. Notwithstanding, when the monolith becomes too cumbersome to deploy ofttimes, you get-go breaking it up into dissever services. Now you have a lot more communication pathways to worry about.

If those services are managed by different teams, and so you lot demand to brand sure every team understands the beliefs of their related services. Conway's Constabulary states that "organizations which blueprint systems ... are constrained to produce designs which are copies of the advice structures of these organizations." Therefore, to be able to improve the communication between services, we cannot ignore the communication between people and teams.

Model Software Communication Afterward Homo Communication

The department of communication studies at a liberal arts higher researches and teaches about interpersonal and intercultural communication. Studying how people communicate, whether to share knowledge, tell a story, or simply get to know one another, tin help us gain an appreciation of common communication challenges, methods for overcoming them, and more than empathy for those nosotros endeavor to communicate with. The lessons can be adapted and applied to many aspects of software engineering.

As distributed systems become more common, we have to get-go thinking differently nearly the communication throughout the organisation. Instead of looking for a great architectural design, start by looking at how people communicate and y'all'll observe a wide variety of successful techniques, some of which may serve as a model for your organization. Humans are able to accept real-time conversations, either in person, over the telephone or video chat, and either one-on-one or in big groups. They also use asynchronous and distributed communication patterns, such equally sending emails or text messages, or leaving a voicemail. In all of them, translation occurs at different stages.

The next fourth dimension you lodge a java at Starbucks, watch as your request is translated (through an anti-corruption layer) into a concise message (in the ubiquitous language) describing your command, and written on a paper loving cup (the transport layer). When your drinkable is prepared, they call your proper noun (raising an event), and you lot retrieve it from the counter (reacting to the event).

Software patterns such equally Control Query Responsibleness Segregation (CQRS), Issue-Driven Architecture, and reactive programming all put an accent on messaging. In CQRS, you send either a command or a query where the intent is conspicuously understood, and the message conveys all the necessary data. EDA and reactive both approach a trouble in a manner humans prefer to carry - when something happens, then I respond accordingly.

Since human communication predates computers by millenia, nosotros have evolved to expect certain patterns of behavior. When creating software, your system volition be far more successful information technology it embraces those patterns, rather than trying to present something new and confusing. Knowing what your users expect, and designing it into your system, requires a certain level of empathy.

The Importance of Empathy

Studying the humanities teaches the states that the world is far more complex than what we can sense  around us. While the same sense of perspective tin can come up from astrophysics, the humanities explore how small changes in location, environment, or historical background - a dissimilar kind of perspective - tin can produce dramatically different outcomes for two groups of people. While it may not be possible to literally put yourself in someone else'southward shoes, taking the fourth dimension to understand their situation can create more empathy towards them.

The Agile Manifesto is comprised of merely 68 words, but information technology could be greatly simplified to "practice empathy." Preferring individuals and interactions over processes and tools, and client collaboration over contract negotiation are nearly creating shared understanding and empathy. When you come across software that has an intuitive user feel it'south not because the developers know the best sorting algorithm to use – information technology's because the software was designed with empathy towards the people who will use information technology.

Practicing empathy goes beyond the user interface. When debugging and troubleshooting, information technology can sometimes go frustrating to the point of declaring everything cleaved and just giving up. Instead of fighting a problems equally a mano a mano battle, employ empathy towards the figurer to endeavor to sympathise why the software isn't working as expected. After all, it isn't doing annihilation you, or some other developer, didn't ask it to do. (And if the computers do actually start thinking for themselves, it's certain to start a lot of philosophical discussions – some other fourth dimension when a liberal arts pedagogy will exist beneficial.)

Critical Thinking and Problem Solving

Every corking developer I've worked with has first-class problem solving skills. I've participated in many technical interviews, on both sides of the table, where the goal wasn't to determine coding power every bit much as information technology was to demonstrate how a person approaches a new problem. In Stalk subjects, the scientific method is frequently employed as a logical set of belittling steps.

At the cadre of the scientific method are the steps of creating a hypothesis, testing the hypothesis with an experiment, then analyzing the data and drawing a conclusion. Information technology may be like shooting fish in a barrel to forget that the process begins with asking a question and doing background enquiry, and ends with communicating your findings. Coming up with a question, determining if it is the right question to ask, and doing background enquiry, all crave critical thinking skills which are the focus of the liberal arts.

Effectively reporting your findings comes back to knowing your audience. If yous wrote a simple paradigm application to examination performance improvement, how would you lot communicate the results to your non-technical product owner? Showing the raw code is probably no more helpful than writing a fifty-page written report. A better arroyo could be demonstrating new functionality using the prototype, or creating a simple chart to summarize improved functioning metrics. Good communication depends on knowing who you're trying to communicate with, and what y'all're trying to communicate to them.

Lifelong Learning

The liberal arts teach the states that the amount of available data is too vast for anyone to know everything, and in that location are always ample opportunities to learn more. The importance of learning over knowing is a view echoed by agile coaches who emphasize having a growth, and non fixed, mindset. Considering technology evolves so rapidly, expert developers already know they must constantly learn about new programming languages, frameworks, and platforms. However, great engineers realize that continuing to acquire almost not-technical aspects of software evolution improves their ability to piece of work with a team and evangelize meliorate solutions.

A liberal arts didactics teaches how to utilize a broad noesis base to clarify new and unfamiliar topics. Subjects that may seem completely unrelated to software development tin provide new insights and perspectives that shine a light on technical tasks. Studying interpersonal advice tin can atomic number 82 to a better microservices compages. Reading a novel and studying social sciences both lead to greater empathy. Empathy helps y'all know your audience and create bang-up software that delights your customers.
