The business as a connected system

Overview

Ridgeway Containers, an established manufacturer, usually sells 80 reusable shipping crates per week. A customer wants another 40 each week, starting immediately. Sales wants to accept. The packing supervisor says the delivery promise is impossible with current staffing.

Before accepting, the team needs to check the work and money required to fulfill the order.

Both businesses and all numbers in this lesson are fictional.

Connected decisions

A business is a system: connected people, activities, resources, and decisions that together produce results. A change in one part can alter what another part must do.

Operations means the work of turning inputs, such as materials and employee time, into goods or services. Operations decisions connect directly to marketing promises, staffing, costs, and customer satisfaction. Source: OpenStax.

For any proposed change, trace five connections:

1. Demand: What are customers asking for, in what quantity, by when?
2. Delivery: Which activities must increase, and which cannot?
3. People: What skills and hours are needed? When can they be available?
4. Cash: Which payments come before customer collections?
5. Customer experience: What happens to reliability, quality, and future purchases?

Use operating data to check each connection before deciding.

A feedback loop occurs when a result influences its own future causes. For example, rushed packing may cause damage; replacements then consume packing time, creating more pressure. Check whether this is happening in the business you are assessing.

Capacity and bottlenecks

Capacity is how much work a resource or process can complete in a stated period under stated conditions. A bottleneck is the step whose limited capacity restricts the process's output. Adding resources elsewhere may leave total output unchanged. Source: OpenStax.

Ridgeway's assembly team can complete 150 crates weekly. Packing has 40 productive staff-hours weekly and packs 2.5 crates per hour. Every crate must pass through both steps. Materials and transport are available; there is no opening backlog or finished inventory.

Packing capacity = 40 hours × 2.5 crates per hour = 100 crates per week. Assembly can handle 150, so packing limits completed shipments to 100.

New demand = 80 + 40 = 120 crates per week. Without a change, 120 orders − 100 shipments = 20 additional unshipped crates each week. This accumulating unfinished commitment is a backlog.

Required packing time = 120 crates ÷ 2.5 crates per hour = 48 hours. Ridgeway needs 8 additional productive hours weekly. Hiring an assembly worker would leave the packing problem unresolved.

Staffing and cash

Assume a trained part-time packer can supply those eight hours immediately for $25 per hour, including all employer costs. Each additional crate requires $30 of materials and sells for $60. Existing assembly staff can absorb the extra work within paid hours. Other costs do not change.

That $1,000 is the improvement under these assumptions, not Ridgeway's total profit. Existing costs still exist.

Materials and the packer must be paid before the first new order is collected. Ridgeway therefore needs $1,400 for the first week's additional work. If several weeks of payments precede collection, the cash requirement can be larger. A dated cash plan establishes the amount.

Even with 48 hours, planned packing capacity exactly equals demand. Absence, slow jobs, or rework could break the promise. Check practical capacity and agree realistic delivery dates. A new hire's training delay would also invalidate the immediate-start assumption.

Sales, operations, and finance should jointly confirm the promise. Track completed shipments, overdue orders, defects, and cash due before collections. Order volume alone cannot show whether growth is working.
