Common Pitfalls

- Do not translate as 'неэффект' (non-existent). Use 'неэффективность' or 'нерациональность'. Avoid confusing with 'некомпетентность' (incompetence), which is more about ability than process.
Common Mistakes
- Misspelling as 'inefficency' (missing 'i'). Using as an adjective (e.g., 'an inefficiency process' – should be 'inefficient process').
