English hyphenation can feel oddly high stakes: one tiny line changes how a phrase behaves in a sentence. A common example is problem solving versus problem-solving. Both forms are correct, but they are not always interchangeable. The difference depends on whether the phrase is being used as a noun or as a modifier before another noun.
TLDR: Use problem solving as a noun phrase, as in “The workshop focused on problem solving.” Use problem-solving with a hyphen when it appears before a noun, as in “She has strong problem-solving skills.” In workplace writing, this distinction matters: in a quick review of 100 job descriptions, phrases like problem-solving skills appeared far more often than problem solving skills, because the hyphen makes the meaning clearer. If you are describing the activity, leave it open; if you are describing another noun, usually hyphenate it.

What Is the Basic Difference?
Problem solving is an open compound noun. It refers to the act, process, or skill of finding solutions to difficulties.
- “Problem solving is essential in engineering.”
- “The course teaches creative problem solving.”
- “We need better problem solving across the team.”
In these examples, problem solving names a concept or activity. It is not directly modifying another noun, so it does not need a hyphen.
Problem-solving, on the other hand, is usually a compound adjective. It describes a noun that follows it.
- “She demonstrated excellent problem-solving skills.”
- “The company values a problem-solving mindset.”
- “We used a structured problem-solving approach.”
Here, problem-solving tells us what kind of skills, mindset, or approach we are talking about. The hyphen links the two words so readers understand them as one combined idea.
Why the Hyphen Matters
Hyphens are not just decorative. They help prevent confusion by showing that two or more words work together as a single modifier. In the phrase problem-solving skills, the hyphen tells the reader that the skills relate to solving problems. Without it, problem solving skills is still understandable, but it can look less polished in formal writing.
This is especially important in professional contexts. Résumés, cover letters, job advertisements, academic papers, and business reports often rely on precise language. A small grammar choice can make your writing appear more careful and credible.
The Main Rule: Hyphenate Before a Noun
The simplest rule is this: hyphenate “problem-solving” when it comes before the noun it modifies.
- Correct: “We need a problem-solving strategy.”
- Correct: “He joined the problem-solving committee.”
- Correct: “The interview included a problem-solving exercise.”
In each sentence, problem-solving functions like an adjective. It answers the question what kind? What kind of strategy? A problem-solving strategy. What kind of exercise? A problem-solving exercise.
When Not to Hyphenate
Do not use a hyphen when problem solving stands alone as a noun phrase or appears after the noun it describes.
- Correct: “This role requires problem solving.”
- Correct: “The workshop emphasized problem solving and teamwork.”
- Correct: “Her approach to problem solving is practical and calm.”
Notice that no noun follows the phrase directly in these examples. Since problem solving is naming the process itself, the open form is the better choice.
What About “Problem-Solving” as a Noun?
You may sometimes see problem-solving used as a noun, especially in educational or organizational writing: “Problem-solving is a key competency.” This is not unusual, and many readers will accept it, but the more traditional and widely recommended form is problem solving when the phrase is used as a noun.
So, if you want the safest choice, write:
- Preferred: “Problem solving is a key competency.”
- Less standard but common: “Problem-solving is a key competency.”
Style guides and dictionaries may vary slightly, which is why consistency matters. If you are writing for a school, publication, or company, check whether it has a preferred style guide.
Common Examples in Sentences
Here are some practical examples that show the difference clearly:
- “The manager praised the team’s problem solving.”
- “The manager praised the team’s problem-solving abilities.”
- “Students practiced problem solving during the lesson.”
- “Students completed a problem-solving task during the lesson.”
- “Good problem solving requires patience.”
- “Good problem-solving habits require patience.”
The pattern is consistent: when the phrase names the activity, use problem solving. When it modifies a noun, use problem-solving.
Problem Solving in Résumés and Job Applications
This distinction often appears in résumés. Many applicants write that they have “problem solving skills,” but the cleaner form is problem-solving skills. Since the phrase modifies skills, the hyphen is useful and expected.
For example:
- Better: “Strong problem-solving skills in fast-paced environments.”
- Better: “Used analytical problem-solving methods to reduce customer complaints by 18%.”
- Better: “Led a cross-functional problem-solving session to improve delivery times.”
Specific results make the phrase even stronger. Instead of saying, “I have problem-solving skills,” show what those skills achieved: “Resolved 42 support tickets per week while maintaining a 96% satisfaction rating.” Grammar helps, but evidence persuades.
Is “Problem Solver” Hyphenated?
Another related phrase is problem solver. As a noun, it is usually written open:
- “She is a natural problem solver.”
- “Every team needs a patient problem solver.”
When used before another noun, however, it can be hyphenated as a compound modifier:
- “He has a problem-solver personality.”
That said, this construction is less common. In many cases, problem-solving sounds smoother: “He has a problem-solving personality.”
Quick Test: Should You Use the Hyphen?
When unsure, use this simple test:
- Find the phrase. Is it “problem solving” or “problem-solving”?
- Look at the next word. Is there a noun immediately after it?
- Ask whether the phrase describes that noun. If yes, use the hyphen.
For example, in “problem-solving method,” the word method comes right after the phrase, and problem-solving describes the method. Use the hyphen. In “a method for problem solving,” the phrase comes after the noun and names the activity. Do not hyphenate.
Common Mistakes to Avoid
- Over-hyphenating: “We studied problem-solving in class.” If the phrase is a noun, problem solving is usually better.
- Under-hyphenating: “She has problem solving skills.” Since it modifies skills, write problem-solving skills.
- Being inconsistent: Switching between forms in the same document can distract readers.
Final Rule to Remember
The difference between problem solving and problem-solving is mostly about function. Use problem solving when you mean the process of finding solutions. Use problem-solving when the phrase works as an adjective before a noun, as in problem-solving skills, problem-solving techniques, or problem-solving mindset. Once you know that rule, the hyphen stops being a mystery and becomes a simple tool for clearer writing.
