WGU C207 Task 2 Guide: Decision Tree Analysis + Example (2026 Edition)

Updated on: Aug 21, 2026

WGU C207 Task 2, formally titled QUM3 Task 2 under the Data-Driven Decision Making (C207) course, asks you to perform a decision tree analysis on a dataset that is randomized per student ID and then write a structured report explaining your method, results, and recommendation. Because the dataset is unique to you, no single answer key can actually help you pass this task. What helps is understanding how the method works well enough to apply it to whatever numbers you are given.

Most students searching for a C207 Task 2 PDF or a completed example run into the same problem: the finished papers they find online were built on a different student’s dataset. The numbers won’t match yours, and submitting work that mirrors someone else’s structure too closely risks WGU’s similarity checker. This guide takes a different approach: it walks through every rubric requirement in plain language, works through the expected-value method using a fictitious illustrative scenario, and flags the specific mistakes that most often cost students a passing score.

If you get stuck applying this to your actual C207 Task 2 WGU dataset, our tutors are available on WhatsApp for a 1-on-1 walkthrough.

What C207 Task 2 Actually Requires

C207 Task 2, also referenced in WGU’s course materials as C207 QUM3 Task 2, has seven independently scored parts (A–G). If you’ve been looking at a WGU C207 Task 2 example online, you’ll notice the structure follows these same seven sections every time, because the rubric drives the format regardless of which dataset a student received.

• Part A: Describe a business question your scenario raises, and justify why decision tree analysis is the right tool to answer it.
• Part B: Identify the relevant data values: demands, profits per unit, and probabilities.
• Part C: Build a complete decision tree diagram with state-of-nature nodes, calculated payoffs, and expected values, each to two decimal places.
• Part D: Explain how expected value is derived from payoffs, and discuss one limitation each for your data and for the decision tree method itself.
• Part E: Recommend a course of action that is logically supported by your analysis and answers the business question from Part A.
• Part F: Cite any sources you quote, paraphrase, or summarize, in-text and in a reference list.
• Part G: Demonstrate professional, error-free written communication (checked automatically by Grammarly for Education before evaluation).

The most common reason students drop to “Approaching Competence” is treating each part as a standalone checkbox instead of a connected argument. Your business question (A) should set up the data you use (B), which feeds the tree (C), which produces the expected values you explain (D), which directly justifies your recommendation (E). Graders are explicitly looking for that chain of logic.

C207 Task 2 Decision Tree: Why This Method Fits (Part A)

Decision tree analysis is a quantitative decision-analysis method that maps choices, uncertain outcomes, and their associated payoffs into a branching diagram, allowing a decision-maker to compare alternatives using probability-weighted expected values rather than intuition alone (Raiffa, 1968). In the context of C207 Task 2, the decision tree is the analytical engine that connects your scenario’s data values to a defensible recommendation.

The C207 Task 2 decision tree approach is appropriate whenever a decision involves all three of the following:

1. A choice between two or more alternatives (e.g., which product line to pursue, whether to expand or hold)
2. Uncertain future outcomes with assignable probabilities (e.g., high demand vs. low demand)
3. Quantifiable payoffs for each combination of choice and outcome

When you write Part A for your C207 Task 2 WGU submission, don’t just say “decision tree analysis is good for decisions under uncertainty.” Name the actual decision being made, point to the actual source of uncertainty in your dataset (which demand variable, which probability split), and explain why a probability-weighted comparison beats a simpler approach like picking the option with the highest single payoff. Graders read dozens of these submissions every cycle. The ones that name specifics from the scenario stand out from the ones that paraphrase the textbook definition.

Identifying Your C207 Task 2 Excel Data Values (Part B)

Your dataset is accessed by entering your student ID into the Start tab of the “Decision Tree Analysis Resources” spreadsheet. WGU requires Microsoft Excel for full functionality of this file. If you’ve been searching for C207 Task 2 Excel guidance, this is the step where that matters most. The spreadsheet is available free through your Office 365 student subscription, and the scenario data is located in the “Decision Tree Scenario” tab once your ID is entered.

The spreadsheet will give you three categories of values to identify and report in Part B:

• Demands: the different levels of customer demand the business might face (e.g., low, medium, high)
• Profits per unit: what each option earns per unit under each demand scenario
• Probabilities: the likelihood assigned to each demand scenario occurring

Part B is graded on accuracy and completeness, not interpretation. List each value clearly with a one-line description of what it represents in your scenario. Don’t bury these numbers inside a paragraph; present them so the grader can verify them against your spreadsheet at a glance. A small table works well.

C207 Task 2 Worked Example: Building the Decision Tree Diagram (Part C)

Illustrative example only. Uses fictitious data, not WGU’s actual dataset.

Below is a worked example using a fictitious company, “GreenLeaf Beverages,” deciding whether to launch a new product line. This demonstrates the method. Your actual numbers, scenario, and decision will differ.

Fictitious scenario: GreenLeaf Beverages is a regional beverage company that has built its reputation on traditional iced teas sold through grocery and convenience retailers. Market research suggests a growing segment of health-conscious consumers is shifting toward lower-sugar, carbonated alternatives, and GreenLeaf’s leadership team is weighing whether to enter this space with a new sparkling tea line. Launching the line would require upfront investment in production retooling and a marketing campaign, with no guarantee that demand will materialize at the level needed to justify the cost. Leadership has asked the analytics team to evaluate the decision using demand and probability estimates from a recent market survey and competitor benchmarking exercise: market demand could be High (60% probability, based on the proportion of surveyed consumers expressing strong purchase intent) or Low (40% probability, reflecting the risk that the new line underperforms against established competitors). Two outcomes, two probabilities, one upfront choice. That is the structure decision tree analysis maps onto.

Step 1: Lay out the decision node. Start with a square decision node representing the choice (“Launch” vs. “Don’t Launch”).

Step 2: Add state-of-nature nodes. From the “Launch” branch, add a circular chance node splitting into “High Demand” and “Low Demand,” each carrying its assigned probability.

Step 3: Calculate payoffs at each branch end. Multiply the payoff per unit by the relevant volume assumptions from your scenario to get the dollar payoff at each endpoint. Round to two decimal places.

Step 4: Calculate expected value. At the chance node, multiply each branch’s payoff by its probability, then sum:

Expected Value (Launch) = (0.60 × $4.50) + (0.40 × $1.20) = $2.70 + $0.48 = $3.18

Expected Value (Don’t Launch) = $0.00

Step 5: Compare expected values at the decision node. The branch with the higher expected value ($3.18 for “Launch”) is the one your tree should roll back to the decision node.

Apply this same five-step structure to your own dataset’s demand levels, probabilities, and payoffs. The mechanics don’t change, only the numbers do.

A note on scope: This example deliberately stops at the calculation (Parts B–D1). It doesn’t write out a finished business question and justification (Part A), a stated limitation (Part D2), a recommendation paragraph (Part E), or a sample reference list (Part F). Those sections of your report need to be built around your scenario and dataset, not adapted from someone else’s.

Calculating Expected Value (Part D1)

When you explain this step in your report, walk through the formula explicitly rather than just stating the result:

Expected Value = Σ (Payoff at each outcome × Probability of that outcome)

For each chance node, multiply every possible payoff by its corresponding probability, then add those products together. Do this for every branch stemming from your decision node, then compare the totals. The branch with the highest expected value is generally the one your recommendation should support, unless your scenario specifies other constraints like risk tolerance or budget limits.

This fold-back process, working from the endpoints of the tree backward to the decision node, is the standard approach in decision analysis (Raiffa, 1968), and remains the core mechanic taught in modern business statistics courses (The Open University, n.d.).

What Students Say; For Part D

Limitations to Discuss (Part D2)

Part D2 asks for one limitation tied to a data value from Part B, and one limitation of the decision tree method itself. The trap most students fall into when writing this section of their C207 Task 2 is treating their assigned probabilities as if they were certain facts rather than estimates. Your dataset’s probabilities came from somewhere: historical sales, market research, expert judgment. That source is exactly where the data limitation usually lives.

A recognized limitation of the C207 Task 2 decision tree approach more broadly is that the model assumes payoffs and probabilities are known quantities, when in practice they are estimates subject to error (Raiffa, 1968). Categories worth considering, adapted to your own scenario:

Data value limitations:

• Probabilities are often estimates based on historical data or judgment. Actual outcomes can diverge significantly from the assigned figures
• Profit-per-unit figures may not account for variable costs that shift at different demand volumes
• Demand estimates can be affected by external factors (seasonality, competitor actions) not captured in the dataset

Decision tree method limitations:

• The model treats probabilities and payoffs as fixed and known, which understates real-world uncertainty
• It does not account for risk aversion. A lower expected value option might be preferable if it carries significantly less downside variance
• Complex decisions often involve more interdependent variables than a two-branch tree can represent

Pick one from each category that is genuinely supported by your scenario’s data, and explain why it is a limitation rather than just naming it. A named limitation with no explanation will not satisfy the rubric.

Writing Your WGU C207 Task 2 Recommendation (Part E)

Part E is where many students leave points on the table. Looking at any WGU C207 Task 2 example that passed, you’ll notice the recommendation does two things explicitly: it identifies which option produced the higher expected value, and it reconnects that finding directly to the business question posed in Part A, using language from that question, not just a generic “therefore we recommend” closer.

A strong recommendation paragraph for a C207 Task 2 example submission follows this logic chain: “The decision tree analysis produced an expected value of [X] for [Option A] versus [Y] for [Option B]. Based on these results, [Option A] represents the higher-value course of action and directly addresses the business question of [restate Part A question here].” The exact numbers and scenario will differ for every student, but the structure of the argument should look like this in every passing submission.

If your scenario includes constraints beyond expected value, such as a risk tolerance threshold or a budget ceiling, acknowledge those in your recommendation too. Ignoring scenario-specific constraints while recommending the highest EV option can still land you at “Approaching Competence” if the grader can see the constraint was relevant.

Citations & Professional Communication (Parts F–G)

• Use APA format for any in-text citations and your reference list. Even course materials or textbooks you paraphrase need a citation.
• Run your draft through Grammarly for Education before submitting. Part G won’t pass if Grammarly flags substantial unresolved issues, and WGU checks this automatically before evaluation.
• Read your final draft out loud once before submitting. It’s the fastest way to catch awkward phrasing and run-on sentences that Grammarly sometimes misses but a grader will still notice.

WGU C207 Task 2 Complete Example

This example uses a fictitious scenario to demonstrate how to achieve a perfect score on each section of the rubric.

A. Business Scenario Summary

A1. Business Question

A mid-sized technology company, “InnovateTech,” is facing a critical decision regarding its flagship product, the “SmartHome Hub.” The current model is experiencing a decline in sales due to increased competition. The company’s leadership must decide whether to invest a significant amount of capital to develop a next-generation “SmartHome Hub 2.0” or to forgo the investment and discontinue the product line. The core business question derived from this scenario is: Should InnovateTech invest in developing SmartHome Hub 2.0 to maximize expected profit, or should it discontinue the product?

A2. Justification for Decision Tree Analysis

Decision tree analysis is the most appropriate technique for this scenario because it allows for a structured and logical evaluation of decisions under uncertainty. As noted by Sishi and Telukdarie (2021), a decision tree is a tool that supports decision-making through a tree-structured modeling approach to map the possible outcomes of a chain of interconnected choices. InnovateTech’s choice involves a series of sequential decisions and uncertain future outcomes. The company must first decide whether to invest. If it invests, the success of the new product is uncertain and can result in either high market demand or low market demand.

Each of these outcomes leads to a different level of profit. The decision tree framework is ideal for modeling this sequence of events: an initial decision, followed by “chance” (or state-of-nature) nodes representing uncertain market reactions. It then calculates the expected value of each branch, providing a clear, quantitative comparison between the “Invest” and “Don’t Invest” alternatives. This directly addresses the business question by quantifying the financial risk and reward, allowing management to make an informed, data-driven decision that maximizes expected profit.

B. Relevant Data Values

Based on the fictitious scenario provided in the “Decision Tree Analysis Resources” spreadsheet, the following data values are identified as essential for the analysis:

• Demands (State of Nature):

  • High Demand: 10,000 units

  • Low Demand: 4,000 units

• Profits per Unit:

  • Profit per unit in High Demand: $100

  • Profit per unit in Low Demand: $60

• Probabilities:

  • Probability of High Demand: 0.70

  • Probability of Low Demand: 0.30

• Costs (Additional Data Value):

  • Investment Cost for Development: $500,000

• Profit (Payoff) for “Don’t Invest” Alternative:

  • $0 (If the product is discontinued, there is no profit or loss from this line).

C. Data Analysis Using Decision Tree Analysis

A decision tree diagram was constructed in the provided “Decision Tree Analysis Resources” spreadsheet. The analysis follows the “Invest” and “Don’t Invest” alternatives to determine the expected monetary value.

C1. Decision Tree Diagram Components

Below is a textual representation of the calculated components. The full diagram and all calculations are included in the attached Excel spreadsheet.

Decision Node 1: Investment Decision

• Alternative 1: Invest in SmartHome Hub 2.0

  • Investment Cost: -$500,000

  • State-of-Nature Node: Market Demand

    • Branch 1: High Demand

      • Probability: 0.70

      • Payoff Calculation: (Demand * Profit per Unit) – Investment Cost = (10,000 units * $100) – $500,000 = $1,000,000 – $500,000 = $500,000.00

      • Expected Value Calculation: $500,000 * 0.70 = **$350,000.00**

    • Branch 2: Low Demand

      • Probability: 0.30

      • Payoff Calculation: (Demand * Profit per Unit) – Investment Cost = (4,000 units * $60) – $500,000 = $240,000 – $500,000 = -$260,000.00

      • Expected Value Calculation: -$260,000 * 0.30 = **-$78,000.00**

  • Total Expected Value for “Invest” Alternative: $350,000 (High) + (-$78,000) (Low) = $272,000.00

• Alternative 2: Don’t Invest (Discontinue Product)

  • Payoff Calculation: $0 (No revenue or costs)

  • Expected Value Calculation: $0 * 1.00 = **$0.00**

Selected Decision: Based on the comparison of expected values ($272,000 > $0), the best decision is to Invest.

D. Implications of the Decision Tree Analysis

D1. Steps to Determine Expected Value

The expected value is the weighted average of all possible payoffs for a given decision alternative. The process is as follows:

1. Identify Payoffs: For each possible outcome (state of nature), calculate the net payoff. In this case, for each demand scenario, the net profit was calculated by multiplying the demand (units sold) by the profit per unit and then subtracting the initial investment cost.

2. Identify Probabilities: Assign a probability to each state of nature. This probability represents the likelihood of that specific outcome occurring. In the analysis, High Demand was assigned a 0.70 probability, and Low Demand a 0.30 probability.

3. Calculate Expected Value of Each Branch: Multiply the net payoff of each state of nature by its assigned probability. This weights the payoff by how likely it is to occur. For example, the High Demand payoff of $500,000 * 0.70 = $350,000.

4. Sum the Expected Values: Add all the weighted branch values together for a single decision alternative. The sum represents the expected monetary value (EMV) of that choice. For the “Invest” alternative, the sum was $350,000 + (-$78,000) = $272,000.

D2. Limitations of the Analysis

• Limitation of a Data Value (Probabilities): The probabilities assigned to High and Low demand (0.70 and 0.30) are subjective estimates. They are based on market research and expert opinion, but they do not guarantee the actual outcome. If these estimates are inaccurate, the expected value will be significantly different, potentially leading to a different decision. Ansari et al. (2021) highlight that an investor’s risk-taking behavior significantly changes the outcome of the decision-making process, underscoring the importance and potential subjectivity of these probability assessments. Sensitivity analysis should be performed to see how changes in these probabilities affect the result.

• Limitation of the Decision Tree Analysis Itself: A significant limitation is that the decision tree analysis simplifies a complex reality. It assumes that the key outcomes (High Demand and Low Demand) are discrete and that the associated payoffs and probabilities are fixed. In reality, market demand exists on a spectrum. Furthermore, the analysis does not account for intangible factors that are difficult to quantify, such as the impact on brand reputation, the potential for future market share gains, or the ability to pivot if the product fails. As Liao and Liu (2022) note, the objective environment is characterized by uncertainty, and decision-makers have a limited ability to understand it fully, which can lead to an enterprise crisis if not properly anticipated. The decision tree provides a valuable financial framework but should not be the sole basis for the final decision.

E. Recommended Course of Action

Based on the results of the decision tree analysis, InnovateTech should invest in the development of the SmartHome Hub 2.0. The expected value of this decision is $272,000, which is significantly higher than the expected value of discontinuing the product ($0). This recommendation logically addresses the business question by showing a quantifiable financial benefit to the investment. The positive expected value indicates that, on average, the investment will be profitable given the current estimates of demand and costs. This result provides a strong quantitative justification for pursuing the new product development and allocating the necessary capital.

Common C207 Task 2 Mistakes That Drop You to Approaching Competence

• Part A: Justification is generic (“decision trees help with uncertainty”) instead of tied to specific scenario details.
• Part B: Listing data values without specifying which decision or outcome each one belongs to.
• Part C: Missing state-of-nature nodes, or payoffs/expected values not rounded to two decimal places.
• Part D1: Describing the result of the expected value calculation without explaining the step-by-step method.
• Part D2: Limitations are vague or not logically tied to the specific data value or method used.
• Part E: Recommendation doesn’t explicitly reference the business question from Part A.
• Part F: Reference list present but missing matching in-text citations, or vice versa.

WGU C207 Task 2 FAQ

Where do I find my C207 Task 2 dataset?

Your dataset is accessed by entering your student ID into the Start tab of the “Decision Tree Analysis Resources” spreadsheet, found in the Supporting Documents section of the task. The scenario and data are in the “Decision Tree Scenario” tab.

Do I need Excel for C207 Task 2?

Yes. WGU specifies Microsoft Excel (available free via your Office 365 student subscription) for full functionality of the scenario and data file.

Is the Task 2 template required?

No, the template provided is optional, though WGU encourages using it.

How long should the Task 2 report be?

There’s no fixed page count in the rubric. Focus on covering all seven parts (A–G) completely rather than hitting a length target.

What’s a good decision tree analysis example for WGU C207?

Since your dataset is randomized per student, a worked example with different (fictitious) numbers, like the GreenLeaf Beverages scenario above, is more useful for learning the method than a filled-in answer key. A finished answer key won’t match your actual numbers anyway, and submitting work that mirrors someone else’s structure too closely risks tripping WGU’s similarity checker.

Can I submit my Task 2 report as a PDF?

Check your specific task instructions. WGU generally requires Microsoft Word (.doc/.docx) unless another format is specified, and submissions can’t be cloud links (Google Docs, OneDrive, etc.).
