The firm, the interviews, the survey and every figure are composite and illustrative; the research methods and sources cited are real.
Part 1: Research Design
# The Management Decision Problem
Scioto Thermal Imaging must decide whether to move its selling effort from roofing contractors, who order most of its surveys today, to the owners of commercial buildings. That decision depends on knowing how owners buy: who in an ownership firm notices the need, who decides what kind of survey to buy, and who approves the money.
# The Research Problem
The research problem is to identify the roles involved in buying roof condition services within firms that own several commercial buildings, the criteria each role applies, and the point at which spending is approved.
# Research Questions
1. Who first recognizes the need for a roof survey?
2. Who decides what kind of evidence is required, such as a visual inspection, cores or a thermal survey?
3. Who approves the spending, and at what amount does approval move up the organization?
4. How much do buyers value evidence from a source independent of repair contractors?
# Hypotheses
H1: In multi-building ownership firms, approval for roof survey spending above a modest amount rests with asset managers rather than facility managers.
H2: Buyers rate evidence from independent sources as more trustworthy than evidence provided by roofing contractors.
# Method
The study combined qualitative and quantitative methods. Eighteen semi-structured interviews were held with six asset managers, seven facility managers and five property managers at ownership firms in Ohio, Indiana and Kentucky. Each interview lasted about forty-five minutes and followed a guide covering a recent roof problem, how it was handled and who was involved at each step. A twelve-question online survey was then sent to 240 members of a regional facility management association, with 71 responses, a rate of about 30 percent.
Exploring a question through interviews and then testing what emerges with a survey is known as an exploratory sequential design (Creswell & Plano Clark, 2018). The interviews were used to write the survey questions in buyers' own terms. Interview notes were coded for roles, decisions and criteria, following the systematic approach Patton (2015) recommends for qualitative analysis.
# Limits of the Design
The interview sample is small and was recruited through the firm's own contacts, which may favor buyers already open to thermal surveys. The survey reached facility managers more than asset managers, because the association's members are mostly facility staff. Results should therefore be read as indications, not estimates for the whole market.
Part 2: Findings
# Who Initiates
Facility managers initiated the response to roof problems in almost every case described. Fifteen of the eighteen interviewees said that the first action after a leak was a call from a facility manager to a roofing contractor already known to the building. In the survey, 83 percent of respondents said facility staff usually make the first contact with an outside firm.
# Who Specifies
Specification, the decision about what kind of evidence to obtain, was shared. Facility managers often accepted whatever the contractor proposed. Asset managers became involved when the contractor recommended replacement, at which point they frequently asked for a second opinion or for core samples. Property managers in multi-tenant buildings played a coordinating role, arranging access and informing tenants.
# Who Approves
Approval rested with asset managers above a modest threshold. In the survey, 78 percent said that spending above about $5,000 on a single roof required an asset manager's or owner's approval. A typical thermal survey of a large distribution roof costs about $5,000, so it sits right at the threshold, and an annual program across several buildings is well above it. H1 is supported.
The person who makes the first call cannot approve the purchase, and the person who approves it is rarely the one who makes the first call.
# What Buyers Value
Respondents rated how much they trust roof condition evidence from different sources on a five-point scale. Evidence from independent consultants averaged about 4.3; evidence from the owner's own staff about 3.4; evidence provided by roofing contractors about 2.9. H2 is supported. Several asset managers said that they had approved replacements they later suspected were unnecessary and now wanted evidence they could show to lenders and insurers.
Interpreting the Findings: The Buying Center
Webster and Wind (1972) described organizational buying as a process involving several roles: users, influencers, buyers, deciders and gatekeepers. The findings map onto that model. Facility managers act as users and gatekeepers: they experience the problem and decide whom to call. Roofing contractors act as influencers, often the most powerful ones, because they shape what the owner believes is wrong. Asset managers are deciders for larger spending. Property managers coordinate.
The model explains why Scioto's current sales pattern favors contractors. The contractor sits between the facility manager's first call and the asset manager's approval, and it controls what evidence reaches the decider. If Scioto wants owners as customers, it must reach both the gatekeeper and the decider directly.
Implications for Selling
Sell the program to asset managers. Because approval sits with asset managers and an annual program exceeds the approval threshold, the program's value case should be built for them: portfolio-wide evidence, insurer documentation and avoided replacements.
Make the facility manager's first call easy. Facility managers will keep calling someone when a roof leaks. A program that gives them a direct line to Scioto for leak-response flights would make Scioto the first call instead of the contractor.
Lead with independence. Buyers' lower trust in contractor-provided evidence is the firm's strongest argument, and it is only credible if the firm stops selling through contractors.
What Surprised the Firm
Two findings were unexpected. First, several facility managers said they would welcome a regular survey program because it would give them evidence to take to their own managers when asking for repair budgets. The firm had assumed facility managers would see an outside survey as a judgment on their own work. Second, insurers came up in eleven of the eighteen interviews without being asked about, usually as the reason an asset manager had recently become interested in roof condition. That suggests insurer requirements may be a stronger trigger than leaks for program purchases.
Next Steps
A larger survey reaching more asset managers, perhaps through a real estate investment association, would test whether the approval threshold and trust ratings hold beyond the association's facility managers. The firm should also track, for its next fifty owner inquiries, who made first contact and who signed, to confirm the pattern with its own sales data.

The Purdue Global GB530 Unit 3 instructions
In GB530 Unit 3 you design and report research on how a firm's customers buy. Start from the management decision problem and translate it into a research problem, research questions and testable hypotheses. Describe a method suited to business buyers, such as interviews followed by a survey, with the sample, response rate and analysis approach, and state the design's limits before the findings. Report what the evidence shows about who initiates, specifies and approves the purchase and what buyers value. Interpret the findings with a model of organizational buying, and draw implications for selling. Expect about seven pages in two halves, design and findings, citing research methods and buyer behavior sources in APA 7.
Inside the GB530 Unit 3 example
Part 1 sets out the decision to shift selling from contractors to owners, the research problem, four questions and two hypotheses. The method pairs eighteen interviews with a survey of 240 association members, described as an exploratory sequential design after Creswell and Plano Clark, with coding following Patton. Limits come before results. Part 2 reports that facility managers initiate, specification is shared and asset managers approve above about $5,000, supporting the first hypothesis, and the highlighted sentence contrasts the person who phones with the person who signs. Trust ratings support the second hypothesis. Webster and Wind's buying center maps the roles, a section notes two surprises, including insurers as triggers, and implications for selling close it.
Reading the GB530 Unit 3 grading rubric
The GB530 research paper is judged first on its chain of reasoning from management decision problem to research problem, questions and hypotheses. A method suited to business buyers, with sample and response rate stated, earns credit. Stating the design's limits before the findings shows integrity. Reporting who initiates, specifies and approves the purchase, with figures, carries significant weight, because those roles shape selling. Testing each hypothesis explicitly shows rigor. Interpreting findings through a buying center model shows understanding. Implications for selling that follow from the evidence complete it. Creswell and Plano Clark on mixed methods, Patton on qualitative analysis and Webster and Wind on organizational buying make up its APA 7 list.
GB530 Unit 3 help from the desk
Many GB530 Unit 3 papers describe consumer decision stages for a business purchase, which misses the several people involved. Others report interview themes without linking them to the decision the firm must make. A common gap is approval: the person who notices a need is often not the one who signs, and the paper should show where that handoff happens. Some writers overstate small samples. Start from the decision, set questions and hypotheses, describe the method and its limits, report roles with figures, test the hypotheses, interpret with a buying center model and say where selling should go. Recording surprises, such as insurers driving interest, shows the research taught the firm something new.

GB530 Unit 3 questions, answered
Do I need to collect real data for this unit?
Sections differ. A few prompts want a research design alone, others want secondary research, and some want a small primary study. Where real interviews are not required, a proposed or composite study clearly labeled as such is usually acceptable. What matters is that the method fits the questions and the limits of the sample are stated.
How does a buying center differ from consumer decision stages?
Consumer stages follow one person from need to purchase. A buying center recognizes that in organizations several people play different roles, and the person who notices the problem is often not the one who approves the spend. For a business product in GB530, graders usually expect the roles named and each linked to a real job title at the buyer.
How many research questions should the design carry?
Three to five is typical. Each should connect to a decision in your marketing plan, and each should be answerable with the method you choose. A long list of questions suggests the study has no focus, while a single question rarely justifies a research unit. Hypotheses are optional in many sections but strengthen a survey.

What is an exploratory sequential design?
It begins with qualitative work, such as interviews, to learn how buyers think and talk about a purchase, then uses those findings to write a survey that tests the patterns with a larger group.
