FAQ: Business English Vocabulary for Problems at Work
What does "backlog" mean in business?
A backlog is the accumulation of work, tasks, or customer orders that a company has received but not yet processed, completed, or delivered.
Is "backlog" the same as "backorder"?
No, it's not.
Backorder = a specific customer order that cannot be filled yet because the item is out of stock or unavailable.
Example: A customer orders a laptop, but it’s not in stock.
That single order is on backorder.
Backlog = the overall accumulation of uncompleted work or unfulfilled orders, regardless of the reason.
Example: The company has a backlog of 5,000 laptops to assemble and deliver.
What does "inventory" mean?
Inventory is the stock of goods and materials that a company has.
Examples
A clothes shop’s inventory includes the shirts, shoes, and jackets in the store.
A car factory’s inventory includes the parts it has on hand and the cars it has in production.
A restaurant’s inventory includes the food and drinks it has in the kitchen and storage areas.
A bookstore’s inventory is the books on the shelves and in the storeroom.
A furniture store’s inventory includes the chairs, tables, and sofas it has for sale.
Is inventory the same as stock?
Often yes in everyday use. Stock usually means finished goods for sale; inventory can include raw materials and work in progress.
What is a bottleneck in a process?
The slow step that limits the whole process and causes delays.
How do I use bottleneck in a sentence?
Shipping became the bottleneck once demand spiked; we just couldn’t get orders out fast enough.
Hiring is our biggest bottleneck right now — projects are waiting because we don’t have enough engineers.
The bottleneck in this process isn’t sales, it’s production. We can’t make the units fast enough.
Customer support has become the bottleneck; tickets pile up faster than the team can handle them.
Lead time vs turnaround: what’s the difference?
Lead time = the total time from when a customer places an order (or request) until they actually receive the product or service. It covers everything end-to-end.
Example: If you order a laptop today and get it in 10 days, the lead time is 10 days.
Turnaround time = the time needed to complete a specific task, step, or process once work has started. It’s usually your team’s part of the whole lead time.
Example: The repair shop promises a 24-hour turnaround for fixing a phone once you drop it off.
What are KPIs?
Key Performance Indicators: metrics that show if a team or process is meeting goals.
Purchase order vs invoice: what’s the difference?
A purchase order is the buyer’s request to buy. An invoice is the seller’s bill for what was delivered.
What is WIP (work in progress)?
Items that are not raw materials anymore but are not finished products yet.
What does "stockout" mean?
When you run out of an item and cannot fulfill orders until you restock.
How can teams reduce a bottleneck?
Find the real cause of the delay, not just the visible problem.
Use simple tools or software to speed up slow tasks.
Train people to do more than one job so they can help where needed.
Do some steps at the same time instead of waiting for one to finish.
Make it clear who decides so approvals don’t get stuck.
Plan better for busy times so the team is ready.
