Quality Control & Quality Standards
Read/Listen first
During a routine quality meeting, Sara reviewed last week’s inspection reports for the assembly line. The team have already rejected two batches this month because the parts did not meet the company’s internal quality standards. She explained that operators must record every defect immediately so that engineers can find the root cause faster and avoid unnecessary rework. If they ignored small deviations from the tolerance, customers would quickly complain about failures in the field and the company’s reputation would suffer. Sara was frustrated at not being able to stay in the workshop all day, but she was able to propose a simple checklist that inspectors could use before releasing any shipment. Last year they had to update all their procedures, and next month the factory is going to introduce an even stricter standard, so everyone needs to be ready to follow the new process carefully.⚡ Learning goals

⚙️ Rules & Grammar — 4 Structures
1️⃣ Present perfect for recent results
Rule: Use have/has + past participle to talk about recent results that are still relevant now.Examples: The team have already rejected two batches this month.; We have checked all reports today.; She has never missed a quality meeting.
Common pitfall + fix: Learners often use past simple instead of present perfect with time periods that continue (this month, this week). — Use present perfect when the period is not finished.
Choose the best option: The lab ___ three samples this week.
Tip: With “this week”, use present perfect for a result that matters now.
Fill with the best answer: We ___ ___ two major defects today.
Tip: Use “have already found” to show a completed result in the current period.
2️⃣ Past simple for completed inspections
Rule: Use past simple to describe finished checks or actions at a specific time in the past.Examples: Sara reviewed the reports yesterday.; They checked the line last night.; We inspected every shipment before it left.
Common pitfall + fix: Learners sometimes use present perfect with a finished time (yesterday, last night). — Use past simple with finished times.
Choose the best option: The parts ___ our standard last week.
Tip: “Last week” is a finished time, so we use past simple.
Fill with the best answer: We ___ every checklist item yesterday.
Tip: Use the past simple form of “check” with “yesterday”.
3️⃣ Must / have to for obligation
Rule: Use must / have to to talk about strong rules and obligations; use had to for the past.Examples: Operators must record every defect.; Inspectors have to sign the checklist.; Last year we had to update all our procedures.
Common pitfall + fix: Learners sometimes say “musted” for the past. — Use “had to” instead of a past form of must.
Choose the best option: Technicians ___ every defect in the system.
Tip: After “must”, use the base form of the verb without “to”.
Fill with the best answer: Last year we ___ update all our procedures.
Tip: In the past, use “had to” to express obligation.
4️⃣ Conditionals with would for consequences
Rule: Use if + past with would + base verb to talk about imagined consequences if a rule is not respected.Examples: If they ignored small deviations, customers would complain.; If we shipped defects, our reputation would suffer.; If we followed the checklist, we would avoid rework.
Common pitfall + fix: Learners often mix “will” and “would” in the same sentence. — Keep “would” in the result clause when the situation is imagined or unlikely.
Choose the best option: If we sent defective parts, customers ___ immediately.
Tip: Use “would” to describe imagined negative results.
Fill with the best answer: If we ignored tolerance limits, our reputation ___.
