Where Two Sources Meet and Where They Part: A Convergence Note Setting Store Managers' Accounts of a Furniture Retailer's First Holiday Season With an Outside Delivery Firm Beside the Company's Complaint Log for the Same Weeks

The Case and Why Convergence Matters

Brennan Home, a composite chain of seven furniture stores in the Milwaukee and Madison areas, moved home delivery from its own trucks and crews to an outside delivery firm in September 2025, just before the holiday season. My case study asks how the retailer's leaders managed the transition. Store managers, interviewed in spring 2026, described the first holiday season with the delivery firm in detail. The company's customer complaint log records every complaint about delivery by date, store and type. Carter et al. (2014) describe data source triangulation as comparing different sources to see where they confirm or challenge one another. The two sources here are genuinely independent: the managers were interviewed months later from memory, and the complaint log was kept by the customer service team at headquarters as complaints arrived. They could have disagreed, so where they agree it means something.

The Comparison

Table 1

Managers' Accounts and the Complaint Log, November 2025 to January 2026

Complaint figures counted from the log; interview accounts summarized from coded transcripts.

Where the Sources Meet

Both sources show that missed delivery windows dominated the early weeks and that problems eased by January. Managers' memories match the log closely on timing and on the main problem. That convergence strengthens two findings: the transition's worst period was its first two months, and scheduling, not crew behavior, was the main failure.

Where They Part

The sources part on damage. Five of seven managers said damage was rare and no worse than under the company's own crews. The log shows damage complaints more than doubling in December. Several explanations are possible. Managers may not have seen damage complaints, which went to headquarters rather than to stores. Managers may have been reluctant to criticize a decision the owners had made. Or the log may overstate damage if customers reported pre-existing marks once they were complaining about a late delivery anyway. Bowen (2009) cautions that records are shaped by how they are collected; the complaint log records what customers chose to report, not all damage. I will check the log against the delivery firm's damage claims, which the company holds, to see which explanation fits.

The sources also part on store differences. Managers at two suburban stores believed their customers had fewer problems, but once complaints are compared with deliveries made, suburban and urban rates were similar. That divergence suggests a belief that may have shaped how those managers described the transition.

A Third Source to Settle the Damage Question

The delivery firm files a damage claim with Brennan Home whenever its crews report damage or a customer's complaint is accepted. Those claims are a third source, independent of both the managers and the customer service log, since the delivery firm has its own reasons to record damage carefully. If claims rose in December as the log did, the managers' memory is the outlier. If claims stayed flat, the log may be counting customers who added old marks to complaints about lateness. The company has agreed to share claim counts by month, without customer names, and the case will report whichever pattern they show.

What the Note Means for the Findings

Yin (2018) argues that findings supported by converging lines of evidence are more convincing than those resting on one source. The case will report the scheduling problem and the January improvement as well supported. It will report damage as an unresolved disagreement until the claims data are checked, and it will report the suburban managers' belief as a perception that the records do not support. Reporting disagreement openly is part of the evidence, not a weakness in it.
