🔥 Warm-Up (5 minutes)
- In your experience, how has your company handled disruptions to its supply chain, such as delayed shipments or vendor shortages?
- Do you think companies should prioritize cost efficiency (e.g., just-in-time delivery) or resilience (e.g., holding safety stock)? Why?

🧠 Grammar / Strategy Focus
When a sentence begins with a negative or restrictive adverbial — such as not only, rarely, seldom, no sooner, or under no circumstances — the subject and auxiliary (or linking) verb must be inverted, just as in a question, and this structure appears frequently in formal business writing to add emphasis. For example: 'Not only did the strike halt production, but it also forced the company to source materials from an alternate vendor.' When no auxiliary verb is already present, do/does/did must be inserted to permit inversion, as in: 'Rarely does a single disruption affect an entire supply network so severely.'

Following a series of (1) at the regional distribution hub, all department heads are asked to review the revised procurement protocol outlined below before placing further orders.
Owing to congestion at the port and a shortage of available containers, several shipments have been delayed well beyond their scheduled arrival dates. It is recommended that every department (2) its safety stock levels immediately to avoid production slowdowns.
Not only has the disruption affected finished-goods inventory, but it has also (3) the availability of raw materials sourced from our overseas vendors. Staff are therefore instructed to prioritize orders from vendors with proven track records of on-time delivery.
Should any department require expedited freight, requests must be submitted to the logistics team no later than Wednesday. (4) circumstances should orders be placed directly with carriers without prior authorization from this office.
We appreciate your cooperation as we work to restore normal delivery schedules.

Reading Comprehension
For much of the past two decades, manufacturers pursued lean inventory strategies predicated on just-in-time delivery, prioritizing cost efficiency over redundancy. Warehousing space was minimized, safety stock was pared down to negligible levels, and single-source contracts with low-cost vendors became the norm. This approach delivered impressive margins during periods of stability, but it left firms acutely vulnerable to even minor disruptions in the logistics network. When a single supplier faltered — whether due to a labor dispute, a natural disaster, or a geopolitical dispute — production lines across entire industries ground to a halt within days.
In light of these vulnerabilities, a growing number of firms have begun to reassess their sourcing strategies, favoring resilience over marginal cost savings. Rather than relying on a single vendor, companies are diversifying their supplier base across multiple regions, maintaining modest safety stock buffers, and negotiating contracts that allow for flexible order volumes. Some have gone so far as to reshore portions of production entirely, notwithstanding the higher unit costs involved. Industry analysts caution, however, that this shift should not be mistaken for a wholesale abandonment of just-in-time principles; rather, it represents a recalibration in which efficiency and resilience are weighed against one another on a case-by-case basis, depending on the criticality of the component and the volatility of the supplying region.

Conversation (Part 3 style)
Teacher: read the script aloud twice (or record it) at natural speed, then ask students the questions below.
Woman: Have you had a chance to look over the shipment tracking for the Incheon consignment? I'm a little concerned we might not make the production deadline.
Man: I have, actually. It looks like customs held it up for an extra two days, so it won't clear the port until Thursday at the earliest.
Woman: That's cutting it awfully close. Is there any way we could have the freight forwarder expedite it once it clears, or are we just at the mercy of the schedule at this point?
Man: I already put in a request to have it routed by air for the final leg, provided the additional cost doesn't exceed what we'd lose from a production delay.
Woman: Good thinking. Honestly, this is the second time this quarter we've had a bottleneck with this particular vendor — maybe it's worth revisiting whether we diversify our sourcing.
Man: Agreed. I'll raise it at Thursday's procurement meeting, assuming the shipment situation is resolved by then.
