OPM 4150 Module 3 Written Assignment: Public or Private Warehousing, and a WMS Example

Reviewed by Edgar Pennington, MBA Thomas Edison State University Updated October 2026

This OPM 4150 Module 3 sample answers a written assignment on warehousing and information systems in Logistics, from TESU's Bachelor of Science in Business Administration in Operations Management. OPM-4150 asks in this module how firms choose among public, contract and private warehousing, and how information systems run the warehouse. The paper takes up the Harrisburg site the composite Paulsboro distributor chose in Module 1. It compares public warehousing with a private warehouse, computes the breakeven volume at which owning becomes cheaper, recommends renting until volume passes that point and explains how a warehouse management system with bar code scanning would reduce picking errors at both sites.

Rent First, Build Later: Breakeven Analysis for a Second Warehouse

The Options

Gourdin (2006) distinguishes public warehouses, which charge for space and handling as used; contract warehouses, which provide dedicated services under a longer agreement; and private warehouses, owned or leased and run by the firm. Public warehousing turns a fixed cost into a variable one and preserves flexibility. Private warehousing gives control and is cheaper per unit at high, steady volumes. Coyle et al. (2017) add that contract warehousing sits between the two, offering dedicated space and services without the capital commitment of ownership.

Breakeven Analysis

A public warehouse in Harrisburg quoted $2.10 per hundredweight (cwt) for storage and handling. A private warehouse would cost about $480,000 a year in lease, equipment and management, plus $0.80 per cwt in variable labor and supplies.

First-year volume through Harrisburg is forecast at 300,000 cwt, below breakeven, so public warehousing saves about $90,000. If volume grows 20 percent a year as planned, it reaches about 420,000 cwt in year three, where a private warehouse would save about $66,000 a year.

Recommendation on Warehousing

Start with a public warehouse on a two-year agreement. That avoids a fixed commitment while the market in central Pennsylvania is proven, and it lets the distributor learn the site's volume and order profile before designing its own building. Revisit the decision when volume passes about 350,000 cwt, leaving time to lease and equip a private site before breakeven.

Information Systems

Warehouses run on information. Gourdin notes that information systems coordinate orders, inventory and movement across the logistics system. Our Paulsboro warehouse still picks from paper lists, and its picking error rate is 1.2 percent of lines, which means about 300 wrong or missing items a week reach restaurants. The errors are costly: each mis-pick triggers a return trip or a credit, which our customer service team estimates at $38 on average, or about $590,000 a year. Against that, a cloud system and scanners for 40 pickers would cost about $180,000 to install and $45,000 a year to run.

Frazelle (2016) describes a warehouse management system as software that directs receiving, put-away, picking and shipping, and notes that bar code scanning at each step confirms that the right item and quantity are handled. With scanning, pickers scan each item, and the system rejects a wrong product before it leaves the shelf. Distributors that adopt scanning typically cut picking errors sharply.

Radio frequency identification reads tags without line of sight and can count whole pallets at once, but tags cost more than bar code labels, and most of our items are low-value disposables. Bar codes fit our products; RFID could be tested later on high-value equipment such as mixers and ovens.

Recommendation on Systems

Install a cloud-based warehouse management system with bar code scanning at Paulsboro first, then require the Harrisburg public warehouse to connect to it, or choose a provider whose system can share inventory data with ours daily. A target of 0.3 percent picking errors within six months is reasonable.

Conclusion

Breakeven analysis favors renting space in Harrisburg until volume passes about 369,000 cwt, and a warehouse management system with bar code scanning would cut the errors that cost us goodwill with restaurants.

Reading the OPM 4150 Module 3 assignment instructions

This module's written assignments cover warehousing and information systems. Expect to compare public, contract and private warehousing, compute a breakeven volume and explain how information systems such as warehouse management systems, bar codes and RFID support warehouse operations. Show the breakeven calculation and costs on both sides of it, and tie the technology discussion to a specific problem, such as picking errors, rather than describing the systems in general. Quantify the problem an information system would solve, such as the cost of picking errors, and compare it with the system's cost. Name the volume at which you would reopen the warehousing decision. Keep the formula and figures in one table.

How this OPM 4150 Module 3 example is built

The paper defines the three warehousing options. A table computes the breakeven volume and costs at current and future volumes, and the text turns the result into a timeline. A recommendation follows on public warehousing with a review point. A section on information systems ties a warehouse management system and bar code scanning to the current picking error rate, weighs RFID and sets a target. The conclusion links both decisions. The cost of picking errors, about $590,000 a year, is set against the cost of a warehouse management system, which makes the case for the technology in the same terms as the warehousing decision. A reasonable error target closes the systems section.

Reading the OPM 4150 Module 3 grading rubric

Mentors grade this assignment on correct breakeven calculations, accurate explanation of warehousing options and information systems, application to a specific problem and clear writing. Papers that show costs on both sides of breakeven, and set a point for revisiting the decision, show how analysis guides timing. Linking technology to a measured problem demonstrates practical judgment. Weighing RFID against bar codes on cost shows careful thinking. Putting a dollar figure on the problem a system solves, and comparing it with the system's cost, shows business judgment. Mentioning contract warehousing as a middle option shows full command of the choices. Costs on both sides of breakeven turn the formula into a decision timeline for managers. Stating units, such as hundredweight, avoids confusion.

Common OPM 4150 Module 3 mistakes, and how to avoid them

Students lose points by computing breakeven incorrectly, by recommending private warehousing without checking volume or by describing technology without a problem it solves. Others ignore growth. Divide fixed cost by the difference in variable costs. Compare costs at current and expected volumes. Tie systems to measured problems. Set a target for improvement. Put a cost on the problem your technology will solve, and compare it with what the technology costs to install and run. Remember growth: a decision right for this year may be wrong in three, so set a volume at which you will look again.

OPM 4150 Module 3 questions, answered

Where can I find a free OPM 4150 Module 3 sample paper?

A breakeven comparison of public and private warehousing, with a WMS plan, is the assignment above.

How is the breakeven volume between public and private warehousing calculated?

Divide the private warehouse's fixed cost by the difference between the public rate and the private variable cost per unit.

When is public warehousing better?

At low or uncertain volumes, because costs vary with use and no fixed commitment is needed.

What does a warehouse management system do?

It directs receiving, put-away, picking and shipping, and with scanning confirms the right item and quantity.

When is RFID worth its cost?

Typically for higher-value items or where reading many tags at once without line of sight saves labor.
