Writing a character who is good at their job
Competence is one of the most satisfying things to read about. How to show a character's skill convincingly without making them dull.
Readers take a particular pleasure in watching people do things well. A surgeon at work, a detective reading a room, a sailor handling a ship in a storm. Competence on the page is satisfying in a way that is easy to underestimate and harder to write than it looks.
Some of the most enduring characters in fiction are defined by expertise. Arthur Conan Doyle's Sherlock Holmes. Patrick O'Brian's Jack Aubrey and Stephen Maturin. Hilary Mantel's Thomas Cromwell, whose skill at managing people and business drives the Wolf Hall novels.
Show the skill in action
The first rule is that competence must be shown, not asserted. Telling the reader a character is brilliant creates an expectation that the book then has to meet. Showing them doing something brilliant earns belief directly.
The best way to show skill is through specific decisions. An expert notices things others miss and acts on them. Say a character is a restorer of old furniture. Rather than stating that she is the best in the trade, show her running a thumb along a drawer, noticing the tool marks, and knowing at once which parts are original. The reader learns the skill by watching it.
Research what experts notice
Convincing competence depends on detail, and detail depends on research. Not the facts that anyone can look up, but the texture of how a practitioner thinks. What do they notice first? What do they worry about that outsiders never consider? What vocabulary do they use without thinking, and what do they find tedious?
Practitioners are often the best source. Memoirs, trade publications, interviews and time spent watching someone work all help. What you are looking for is judgement, the tacit knowledge that separates an expert from someone who has read the manual.
Be careful not to show off the research. A few precise details, used at the right moments, convince more than long explanations. The reader wants to feel in capable hands, not attend a lecture.
Competence needs resistance
A character who is good at everything and faces problems they can easily solve is not interesting. Competence becomes dramatic when it meets a problem at the edge of its reach. The expert faces a situation their skill almost, but not quite, covers.
Limits are also where character lives. A brilliant detective who is hopeless with people, a gifted surgeon whose confidence turns to arrogance, a skilled fixer whose methods start to cost them. The skill shows what the character can do. The limit shows who they are.
Readers often enjoy the details of how something is done for its own sake. A heist novel is partly about the plan. A novel about a chef lingers in the kitchen. Process can carry chapters, provided it is going somewhere and the stakes are clear.
It helps to explain just enough for the reader to follow and no more. Let the reader work some things out alongside the character. The satisfaction of watching an expert is partly the satisfaction of beginning to understand them.
Competence as characterisation
How a person works reveals a great deal about them. Whether they are careful or improvisational, whether they take shortcuts, how they treat less skilled colleagues. Writing a character at work is one of the most efficient ways to show who they are.
Readers tend to trust capable characters, and to follow them. That trust is worth earning carefully.
