## Introduction
Measuring customer delight is a crucial part of product development and growth. Understanding how users feel about individual features enables product teams to prioritize improvements, plan roadmaps effectively, and enhance user satisfaction. Manual collection and analysis of user feedback can be time-consuming and error-prone, especially when feedback comes from multiple channels. Automating this process saves time, reduces errors, and provides real-time insights.
This guide targets product managers, startup teams, and automation engineers aiming to build an automated workflow to measure customer delight by specific product features using n8n — an open-source workflow automation tool. We will integrate n8n with three commonly used services:
– Google Forms (customer feedback collection)
– Google Sheets (storing and processing feedback data)
– Slack (sending alerts and reports to the product team)
By the end of this tutorial, you will have a robust, scalable automation workflow that captures user feedback, parses it by feature, calculates delight scores, and notifies your team.

## What Problem Does This Solve?
Manual data collection, normalization, and sentiment analysis based on feature-level feedback can be tedious. Without automation, timely customer delight metrics are difficult to achieve.
This workflow benefits:
– **Product teams**: Receive near-real-time insights on which features delight or frustrate users.
– **Customer success teams**: Quickly respond to critical issues or celebrate wins.
– **Executives & stakeholders**: Access KPI dashboards highlighting customer satisfaction per feature.
## Tools and Services Integrated
1. **Google Forms:** Collects structured customer feedback with feature-specific questions.
2. **Google Sheets:** Stores incoming feedback and performs basic data organization.
3. **n8n:** Orchestrates data flow, processes sentiment and delight metrics.
4. **Slack:** Notifies the product team of weekly summaries and urgent issues.

## Step-by-Step Technical Tutorial
### Prerequisites
– Basic familiarity with n8n interface and workflows.
– Google account with access to Google Forms and Google Sheets.
– Slack workspace where notifications will be sent.
### Step 1: Design your Google Form for Feature-based Feedback
– Create a Google Form with questions structured to collect feedback per feature, for example:
– “Rate Feature A from 1 to 5”
– “Your comments about Feature A”
– Repeat for each feature you want to track.
– Optional: Add overall satisfaction and user metadata.
– Configure the form to save responses to a Google Sheet.
### Step 2: Set up Google Sheets to Store and Preprocess Feedback
– Your linked Google Sheet will automatically populate rows on new responses.
– Add columns for calculated sentiment or delight score placeholders.
### Step 3: Configure n8n Trigger to Poll Google Sheets
– In n8n, create a new workflow.
– Add the **Google Sheets Trigger** node.
– Configure it to watch your feedback sheet for new rows (Form responses).
– Ensure credentials are properly configured to allow N8N access.
### Step 4: Parse Incoming Feedback Data
– Add a **Set** or **Function** node to parse the specific columns related to each feature rating and comments.
– Extract feature names, ratings, and comments for analysis.
### Step 5: Sentiment Analysis (Optional Enhancement)
– To deepen insights, use n8n’s HTTP Request node to call a sentiment analysis API (e.g., Google Natural Language API, or a free alternative).
– Send the feature comments text.
– Retrieve sentiment scores (e.g., positive, negative, neutral).
– Combine these with numeric ratings for a holistic delight score.
### Step 6: Calculate Delight Scores
– Use a **Function** node to compute a weighted delight score per feature.
– Example formula: Delight Score = (Rating * 0.7) + (Sentiment Score * 0.3)
– Normalize scores between 0-5 or 0-100 for consistency.
### Step 7: Append Data Back to Google Sheets
– Use the **Google Sheets** node to append calculated delight scores and sentiment analysis results into a separate sheet or columns.
– This data will be used for further reporting and alerts.
### Step 8: Conditional Alerts via Slack
– Add a **IF** node to evaluate if any feature’s delight score falls below a threshold (e.g., less than 3/5).
– If true, use the Slack node to send an alert message to a dedicated product channel containing:
– Feature name
– User comments (if any)
– Delight score
– Timestamp
### Step 9: Generate Weekly Summary Reports
– Schedule a **Cron** node to run weekly.
– Fetch aggregated delight scores from Google Sheets.
– Compile summary statistics and top/bottom performing features.
– Post this summary in Slack using a Slack node.

## Breaking Down the Workflow Nodes
1. **Google Sheets Trigger:** Captures new user feedback as it arrives.
2. **Set/Function Node (Parsing):** Extracts feature-specific data points.
3. **HTTP Request (Sentiment API):** Enriches qualitative feedback into quantitative sentiment scores.
4. **Function (Delight Score Calculation):** Combines numeric and sentiment ratings.
5. **Google Sheets Append:** Stores calculated data for future reference.
6. **IF Condition:** Decides if notification is required based on score thresholds.
7. **Slack Node:** Communicates insights to product teams.
8. **Cron Node:** Automates scheduled weekly reporting.

## Common Errors and Tips for Robustness
– **Auth Failures:** Ensure OAuth credentials for Google and Slack are correctly configured and not expired.
– **API Rate Limits:** Sentiment APIs can have usage limits; batch requests or cache results.
– **Data Consistency:** Validate form inputs to prevent blank or invalid ratings.
– **Error Handling:** Use n8n’s error workflow or continue-on-fail settings to prevent workflow breaks.
– **Time Zones:** When scheduling reports, account for your team’s local time zone.

## Scaling and Adapting the Workflow
– **Add More Feedback Channels:** Integrate email surveys, app feedback APIs, or CRM data.
– **Advanced Analytics:** Connect with BI tools like Google Data Studio or Metabase via Google Sheets for visualization.
– **More Granular Features:** Expand your form and parsing logic to handle sub-features or components.
– **Multi-language Support:** Incorporate language detection and multilingual sentiment services.
– **Real-Time Dashboards:** Use Webhook triggers or socket connections for immediate updates.
