"Without data, you're just another person with an opinion." — W. Edwards Deming
The Problem That Started This Guide
A client recently exported hundreds of keywords from Google Keyword Planner. They had no idea which ones to target, how to group them by topic, or where to begin. They were about to pick based on gut feel.
We showed them that a simple NLP clustering model could automatically group all those keywords by topic and search intent, then a scoring model could rank each cluster by opportunity — volume vs. competition vs. business relevance. What would have taken days of manual work was done in minutes, with data.
That is the power of data science applied to real decisions.
This guide compiles 45 proven use cases across 9 business domains where data science, machine learning, and AI create measurable, real-world value — not theoretical value, but money saved, revenue gained, and decisions made with evidence instead of guesswork.
All 45 use cases in a shareable, printable document.
What We Cover
Why Data Science Is Now a Business Necessity
Data science was once perceived as a luxury — something only Google, Amazon, or Netflix could afford. That perception is completely outdated.
The tools, the talent, and the infrastructure needed to apply machine learning to business problems are now accessible to organisations of every size. Open-source libraries like scikit-learn, TensorFlow, and Hugging Face have democratised capabilities that cost millions to build a decade ago.
The real question today is not: "Can we afford to use data science?"
The real question is: "Can we afford not to?"
Here is what typically happens in a business without data science:
Decisions are made by intuition or by whoever speaks loudest in the room
Spreadsheets are pushed beyond their analytical limits
Strategy is reactive rather than proactive
Opportunities are identified only after competitors have already acted on them
Here is what changes when data science is applied correctly:
Patterns invisible to humans become clear
Predictions replace guesses
Resources flow to what actually works
The business develops a competitive advantage that compounds over time
Key insight: Data science is not a technical exercise — it is a business discipline. The goal is never to build a model. The goal is always to make a better decision. Every technique in this guide serves that purpose.
1. Marketing & SEO — Smarter Content Decisions
Marketing teams generate enormous amounts of data — keyword lists, campaign results, audience segments, traffic reports — but most of it sits unanalysed. Data science changes that entirely.
Use Case 01 — Keyword Clustering & Prioritization
The Problem: You export 500 keywords from Google Keyword Planner. They are a wall of data. You don't know which topics they represent, which intent they signal, or where to begin.
The Approach: An NLP clustering model (TF-IDF vectorisation + K-Means) automatically groups keywords by topic and search intent. A scoring model then ranks clusters by volume, keyword difficulty, and business relevance into a clear opportunity score for each group.
The Outcome: You discover that your 500 keywords represent 18 core topics, 3 of which are high-volume and low-competition, and your site currently ranks for only 4. A clear, data-backed content roadmap emerges in hours.
Use Case 02 — Content Gap Analysis Against Competitors
The Problem: Competitors rank for topics your site doesn't cover, but you don't know exactly what's missing or which gaps are worth pursuing.
The Approach: Web scraping and NLP extract all topics from top-ranking competitor content. Topic modelling identifies what they cover that you don't, ranked by traffic potential.
The Outcome: A prioritised list of content to create — topics your competitors have already validated with real search traffic. No more guessing what to write next.
Use Case 03 — SEO Traffic Forecasting
The Problem: Before investing in content, you want to know how much traffic a topic is actually likely to generate — not an estimate, a projection.
The Approach: Regression models on historical CTR and rank-to-traffic data, combined with Prophet time-series forecasting, project traffic trajectories for each content topic.
The Outcome: Data-backed projections that justify content investment before a single word is written and set realistic expectations with stakeholders.
Use Case 04 — Multi-Touch Attribution Modelling
The Problem: Budget is spread across SEO, paid ads, email, and social — but nobody knows which channels actually drive conversions, or whether the last-click model is misleading everyone.
The Approach: Shapley value attribution or Markov chain models assign conversion credit across all customer touchpoints fairly — based on genuine influence, not position in the funnel.
The Outcome: Budget reallocated to channels that actually influence decisions. Marketing ROI improves without increasing total spend.
Use Case 05 — Customer Segmentation for Campaigns
The Problem: The same email and ad creative goes to your entire list, producing low engagement across the board.
The Approach: RFM analysis and K-Means clustering group customers by behaviour. Separate models predict each segment's response to different messages and offers.
The Outcome: Hyper-targeted campaigns that significantly increase open rates, click-throughs, and conversions over batch-and-blast approaches.
Use Case 06 — Ad Copy Performance Prediction
The Problem: Multiple ad variants are running simultaneously and budget is burning on losers while the winner is slowly identified.
The Approach: Multi-armed bandit algorithms dynamically allocate budget toward better-performing variants in real time. NLP feature analysis identifies which language patterns drive conversion.
The Outcome: Faster discovery of winning copy, lower cost-per-acquisition, and lasting insight into what messaging resonates with each audience.
2. Sales & CRM — Predictive Revenue Intelligence
Sales teams generate a continuous stream of data through their CRM — engagement history, deal stages, contact records, activity logs. Machine learning transforms this from a record-keeping system into a predictive revenue engine.
Use Case 07 — Lead Scoring & Prioritization
The Problem: Sales reps spend equal time on every lead in the queue — including the ones that will never convert. There is no data-driven way to prioritise the day.
The Approach: A logistic regression or gradient boosting model trained on historical CRM data assigns each lead a conversion probability score using company size, industry, engagement signals, email opens, and time since last contact.
The Outcome: Reps work a ranked list every morning. The top 20% of leads identified by ML typically account for 70–80% of actual conversions. Sales productivity improves without adding headcount.
Use Case 08 — Customer Churn Prediction
The Problem: Customers cancel and the first signal leadership receives is the cancellation email. No warning. No chance to intervene.
The Approach: Survival analysis or XGBoost monitors usage patterns, support ticket frequency, payment behaviour, and engagement drops. A churn risk score is generated for every account, updated weekly.
The Outcome: Accounts at risk of cancellation are visible 60–90 days before the decision is made. Proactive retention outreach becomes possible. Typical churn reduction: 20–40%.
Use Case 09 — Sales Revenue Forecasting
The Problem: Monthly forecasts are built manually in spreadsheets and are consistently inaccurate, which affects every downstream planning decision.
The Approach: Time-series models — ARIMA, Prophet, LSTM — trained on historical bookings, pipeline stages, deal velocity, and seasonality signals produce automated, updated forecasts.
The Outcome: Accurate forecasts that improve hiring plans, financial planning, capacity management, and investor communications. Forecasting goes from a days-long manual exercise to an automated daily output.
Use Case 10 — Upsell & Expansion Opportunity Detection
The Problem: Existing customers are ready to buy more, but nobody knows who they are. Significant revenue is left on the table every quarter.
The Approach: An ML model on product usage intensity, company growth signals (new hires, funding rounds, web traffic growth), and purchase history identifies expansion-ready accounts.
The Outcome: Sales team receives a prioritised upsell list each week. Net Revenue Retention improves without increasing acquisition cost.
Use Case 11 — Deal Win Probability Scoring
The Problem: The pipeline looks healthy on paper, but there is no reliable way to predict which deals will actually close this quarter.
The Approach: A real-time classification model uses deal stage, engagement frequency, stakeholder count, time-in-stage, and historical win/loss data to score each deal's probability continuously.
The Outcome: Accurate pipeline health visibility. Managers can focus coaching where it will have the most impact. Forecast accuracy improves significantly.
3. Finance & Risk — Protecting the Bottom Line
Finance is one of the highest-value domains for data science because every decision is directly tied to money. The models don't need to be perfect — they just need to be better than what's currently in place. That bar is almost always achievable.
Use Case 12 — Real-Time Fraud Detection
The Problem: Rule-based fraud filters are either too strict (blocking legitimate customers) or too loose (letting fraud through). There is no middle ground with static rules.
The Approach: Anomaly detection models — Isolation Forest, autoencoders — learn each user's normal transaction behaviour. Any transaction deviating significantly from that user's personal pattern is flagged in real time, regardless of amount or location.
The Outcome: Fraud caught contextually, at a level rule-based systems fundamentally cannot reach. Fewer false positives frustrating legitimate customers. Lower fraud losses.
Use Case 13 — Credit Risk Scoring
The Problem: Manual borrower assessment is slow, inconsistent across analysts, and misses patterns that structured data contains.
The Approach: Gradient boosting on financial history, behavioural data, and alternative signals like utility payments and rental history produces a probability-of-default score for each applicant.
The Outcome: Faster approvals, lower default rates, fairer lending decisions, and explainable model outputs that satisfy compliance requirements.
Use Case 14 — Cash Flow Forecasting
The Problem: Finance teams are perpetually reactive — unable to anticipate shortfalls or surpluses more than a few days ahead.
The Approach: Time-series models combining historical cash flows, AR/AP aging, seasonal patterns, and business calendar events project cash positions 30–90 days forward.
The Outcome: Proactive treasury management. Financing arranged before it is urgently needed. Surplus cash deployed rather than sitting idle.
Use Case 15 — Expense Anomaly Detection
The Problem: Expense reports contain policy violations, errors, and potential fraud that manual audit processes routinely miss.
The Approach: Unsupervised clustering and learned anomaly detection flag suspicious patterns in expense categories, amounts, vendors, and submission timing before reimbursement is processed.
The Outcome: Suspicious expenses caught before payment. Audit efficiency increases dramatically. Policy compliance improves across the organisation.
Use Case 16 — Invoice Processing Automation
The Problem: AP teams manually key invoice data — slow, error-prone, and consuming labor that could be redirected to higher-value work.
The Approach: OCR and NLP document-understanding models extract vendor name, line items, amounts, and due dates from any invoice format — structured or unstructured — automatically.
The Outcome: 80–90% of invoices processed without human touch. AP team focuses entirely on exceptions and cash management strategy.
4. Supply Chain & Operations — Efficiency at Scale
Supply chain decisions are repeated thousands of times daily. Even marginal improvements in each individual decision compound into enormous annual savings.
Use Case 17 — Demand Forecasting by SKU
The Problem: Demand planning uses last year's numbers adjusted by gut feel. You are always either overstocked on slow movers or caught short on bestsellers.
The Approach: Hierarchical time-series models — Prophet, LightGBM — forecast demand at the individual SKU level, incorporating promotions, seasonality, holidays, and competitor pricing signals as features.
The Outcome: Inventory aligned to real expected demand. Carrying costs and write-offs fall. Stockouts that cost sales become rare events rather than routine problems.
Use Case 18 — Inventory Optimisation
The Problem: Significant working capital is tied up in slow-moving stock while fast-moving items run out repeatedly.
The Approach: Simulation and reinforcement learning find optimal reorder points, safety stock levels, and order quantities for each SKU — balancing service level against holding cost.
The Outcome: Working capital freed from dead inventory. Stockout rates reduced. Warehouse space and carrying costs optimised simultaneously.
Use Case 19 — Supplier Risk Assessment
The Problem: Supplier disruptions catch you by surprise. There is no systematic early warning system for vulnerability or failure.
The Approach: Multi-factor risk scoring using delivery history, supplier financial health signals, geopolitical risk data, and NLP-based monitoring of supplier-related news and events.
The Outcome: Early warning before disruptions occur. Proactive supplier diversification built before it is urgently needed. Supply chain resilience becomes a managed asset.
Use Case 20 — Delivery Delay Prediction
The Problem: Customers receive late-delivery notifications only after delays happen — always reactive, never proactive.
The Approach: A classification model trained on carrier performance data, weather patterns, route congestion history, and package characteristics predicts delay probability at the moment of shipment.
The Outcome: Proactive customer communication before delays occur. Support ticket volume drops. CSAT improves without changing the underlying logistics.
Use Case 21 — Last-Mile Route Optimisation
The Problem: Delivery routes are planned manually or with basic tools — fuel, time, and vehicle capacity are wasted on every run.
The Approach: Vehicle routing optimisation using Google OR-Tools with real-time traffic data, time window constraints, load capacity, and driver schedules.
The Outcome: 15–25% reduction in delivery costs. More stops per route. Measurably lower carbon footprint per delivery.
5. HR & Talent — People Analytics That Work
HR sits on data that is almost never analysed systematically. Engagement scores, performance histories, compensation data, and career trajectories contain patterns that predict attrition, performance, and organisational gaps months before they become visible problems.
Use Case 22 — Employee Attrition Prediction
The Problem: Key employees resign without warning. Replacement costs average 1–2× annual salary. It is nearly always preventable with enough lead time.
The Approach: Survival analysis or XGBoost on engagement survey scores, performance trajectory, time since last promotion, compensation relative to market, and team dynamics assigns a flight risk score per employee — updated quarterly.
The Outcome: Flight risks identified 6–12 months before resignation. Targeted, cost-effective retention action taken before the employee begins looking externally.
Use Case 23 — Resume Screening & Candidate Matching
The Problem: Recruiters spend hours screening resumes. The majority of time is wasted on unqualified or irrelevant candidates.
The Approach: NLP embedding models — BERT, sentence transformers — match resume content against job requirements at scale with consistent, bias-aware criteria applied uniformly.
The Outcome: Top candidates surfaced in minutes, not hours. Consistent screening quality across all roles. Recruiter time redirected to building relationships and conducting meaningful interviews.
Use Case 24 — Performance Prediction & Development Planning
The Problem: Performance reviews are subjective, infrequent, and retrospective. High-potential employees are identified too late — often after they have already left.
The Approach: Regression model on activity signals, peer feedback patterns, goal completion rates, and learning engagement predicts each employee's performance trajectory.
The Outcome: Early identification of high performers and development opportunities. Coaching targeted to where it will have the most impact. Development conversations happen before performance dips.
Use Case 25 — Workforce Demand Planning
The Problem: Hiring is perpetually reactive — you are always behind in some teams and over-staffed in others, with no systematic way to predict where gaps will emerge.
The Approach: Time-series forecasting on business growth metrics projects headcount needs by role, team, and location 6–18 months ahead.
The Outcome: Strategic hiring aligned to actual business growth. Recruiting pipelines built before roles open urgently. Time-to-fill and cost-to-hire both reduced.
Use Case 26 — Employee Sentiment Analysis
The Problem: Annual engagement surveys don't capture real-time sentiment — culture problems fester undetected between survey cycles.
The Approach: NLP on open-text survey responses, external review platforms, and internal feedback channels surfaces emerging themes and sentiment trends automatically and continuously.
The Outcome: Real-time culture health monitoring across teams and departments. Issues detected and addressed before they affect performance, attrition, or employer brand.
6. Customer Experience — Understanding Every Interaction
Customers leave signals everywhere — in reviews, support tickets, NPS responses, chat logs, and behavioural data. Data science allows you to hear every customer, at scale, with quantified clarity rather than anecdotal summaries.
Use Case 27 — Aspect-Based Sentiment Analysis on Reviews
The Problem: You receive 3,000 customer reviews a month. Your team reads 50 of them and makes product decisions based on that sample. The other 2,950 are unread data.
The Approach: A fine-tuned NLP model performs aspect-based sentiment analysis — extracting not just overall sentiment, but which specific dimensions (shipping, product quality, customer service, packaging, pricing) are mentioned and how customers feel about each one.
The Outcome: Quantified insight from 100% of customer feedback. Product teams get data, not anecdotes. Priority issues surface automatically. Positive signals are identified just as clearly as problems.
Use Case 28 — Customer Lifetime Value Prediction
The Problem: All customers receive the same service level, but some generate 10× more value than others over their lifetime with your business.
The Approach: BG/NBD or ML-based CLV models using purchase frequency, recency, monetary value, and category affinity predict the future value of each customer.
The Outcome: Tiered customer strategy built on data. High-CLV accounts receive premium attention. Acquisition budget targets lookalike profiles of your most valuable customers.
Use Case 29 — Support Ticket Auto-Routing
The Problem: Support tickets land in a general queue and are manually triaged — first response times suffer and routing errors frustrate customers who get passed around.
The Approach: Multi-class text classification using a fine-tuned transformer model automatically categorises each ticket by issue type and routes it to the correct specialist team at submission.
The Outcome: Faster first response. Right agent, first time. Support capacity scales without proportional headcount growth.
Use Case 30 — NPS Driver Analysis
The Problem: You know your NPS score, but the specific factors driving promoters vs. detractors are not quantified — so you don't know what to fix first.
The Approach: Regression analysis and NLP on open-text NPS responses quantify the statistical impact of each touchpoint, interaction type, and service dimension on the overall score.
The Outcome: A ranked list of what to improve for maximum NPS lift. Investment concentrated on the highest-impact areas rather than spread thinly across guesses.
Use Case 31 — Personalisation Engine
The Problem: Every customer sees the same homepage, the same emails, and the same product listings — engagement is low and bounce rates are high because the experience is not relevant.
The Approach: Collaborative filtering and content-based recommendations updated continuously by real-time user behaviour signals serve each user a genuinely personalised experience.
The Outcome: Higher engagement, longer session duration, and 15–30% conversion uplift. Customers stay longer and buy more because the experience feels tailored to them.
7. E-commerce & Retail — Personalisation That Converts
E-commerce generates a continuous, real-time stream of behavioural data — every click, scroll, product view, and abandoned cart. Used correctly, this data allows you to serve each customer an experience that feels individually designed.
Use Case 32 — Product Recommendation System
The Problem: The "customers also bought" section shows generic or irrelevant products, missing significant cross-sell revenue sitting right there in the transaction data.
The Approach: Matrix factorisation (ALS) and neural collaborative filtering analyse purchase and browse history across all customers to generate personalised recommendations for each individual user in real time.
The Outcome: Higher average order value. Customers discover products they genuinely want but would not have searched for independently. Amazon attributes approximately 35% of revenue to its recommendation engine — the underlying technology is open source.
Use Case 33 — Dynamic Pricing Optimisation
The Problem: Prices are set manually and rarely updated — margin is left on the table or sales are lost to competitors who price more dynamically.
The Approach: Price elasticity modelling combined with real-time competitor price monitoring suggests optimal prices by product, customer segment, and demand signal.
The Outcome: Margin improvement of 5–15% without losing volume. Competitive pricing maintained without triggering a race to the bottom.
Use Case 34 — Return & Refund Risk Prediction
The Problem: High return rates are eroding margins and there is no systematic way to predict which orders will come back before they ship.
The Approach: A classification model on product type, customer return history, purchase channel, and size or fit signals predicts return probability at the time of order placement.
The Outcome: High-risk orders flagged for proactive intervention — a better product description, a sizing guide, a confirmation message. Return rates fall. Margins improve.
Use Case 35 — Visual Product Search
The Problem: Customers often cannot describe what they want in words. They leave your site without buying because keyword search cannot bridge the gap.
The Approach: Computer vision embeddings — CLIP, ResNet — enable image-based search: customers upload any photo and instantly find visually similar products in your catalogue.
The Outcome: Customers discover products they could not search for. Discovery rates and basket sizes increase. A meaningful gap in the shopping experience is closed.
Use Case 36 — Market Basket Analysis
The Problem: You know anecdotally that some products are bought together, but have no systematic data on statistically significant pairings to act on.
The Approach: Apriori and FP-Growth algorithms applied to transaction data surface statistically significant product associations and bundle candidates at any scale.
The Outcome: Data-driven bundling, promotional pairing, and product placement decisions that measurably increase basket size and cross-sell conversion.
8. Healthcare — Saving Time and Lives with Data
Healthcare generates some of the most complex and highest-stakes data in any industry. Data science here is not just about efficiency — it directly affects patient outcomes, safety, and the quality of care delivered.
Use Case 37 — Patient Readmission Risk Scoring
The Problem: Hospitals face financial penalties for preventable 30-day readmissions but lack a systematic way to identify which patients need extra follow-up at discharge.
The Approach: A gradient boosting model trained on diagnosis codes, lab results, medication lists, social determinants of health, and discharge characteristics generates a readmission risk score for each patient.
The Outcome: High-risk patients receive targeted, structured follow-up. Readmission rates fall. Quality scores and reimbursement outcomes improve. Preventable readmissions become genuinely preventable.
Use Case 38 — Appointment No-Show Prediction
The Problem: No-shows waste provider time and reduce care access for other patients — standard reminder systems are not solving the problem at the root.
The Approach: A classification model on patient history, appointment type, transportation access, weather, and day-of-week patterns predicts no-show probability per appointment.
The Outcome: Targeted outreach for high no-show risk patients. Dynamic overbooking fills slots that would otherwise be wasted. Provider revenue and patient care access both protected.
Use Case 39 — Clinical Notes Information Extraction
The Problem: Valuable clinical information is locked in unstructured physician notes — impossible to analyse, aggregate, or act on at any meaningful scale.
The Approach: Medical NLP models — BioBERT, spaCy with clinical pipelines — extract diagnoses, medications, symptoms, and outcomes from free-text clinical records automatically.
The Outcome: Structured, queryable data from unstructured notes. Population health analytics, quality improvement reporting, and clinical research become feasible at scale.
Use Case 40 — Drug Interaction & Contraindication Alerts
The Problem: Clinicians see hundreds of patients daily and can miss dangerous drug combinations or patient-specific contraindications under time pressure.
The Approach: A knowledge graph combined with ML on prescribing patterns and individual patient profiles flags potential interactions at the point of order entry in real time.
The Outcome: Medication errors reduced. Patient safety measurably improved. Clinical liability and malpractice exposure reduced for providers and institutions.
9. Business Intelligence — Seeing Around Corners
Traditional BI tells you what happened. Data science tells you what is happening right now and what is likely to happen next. That shift from descriptive to predictive and prescriptive intelligence is where the most strategic value lives.
Use Case 41 — KPI Anomaly Detection & Automated Alerting
The Problem: Something breaks in the business metrics on a Tuesday. Nobody notices until the Friday review meeting — four days of compounding damage goes unaddressed.
The Approach: Statistical process control combined with ML anomaly detection — Isolation Forest, Prophet changepoint detection — monitors every KPI continuously and alerts within hours of any significant deviation.
The Outcome: Problems caught and addressed in hours, not days. Positive anomalies — an unexpected traffic spike, a conversion surge — are capitalised on just as quickly as negative ones.
Use Case 42 — Competitive Intelligence Monitoring
The Problem: Tracking competitor moves — pricing changes, product launches, messaging shifts, hiring signals — is manual, slow, and always behind.
The Approach: Automated web scraping and NLP continuously monitor competitor websites, press releases, job postings, pricing pages, and review platforms.
The Outcome: A real-time competitive intelligence feed. Strategic shifts in the market are detected early, before they show up in analyst reports months later.
Use Case 43 — Market Trend Forecasting
The Problem: Strategic decisions are based on analyst reports that are months old by the time they are published and acted upon.
The Approach: Time-series trend analysis on search volume, social signals, patent filings, and news volume detects emerging trends weeks or months before they become obvious to the broader market.
The Outcome: First-mover advantage on emerging opportunities. Strategy built on leading indicators, not lagging ones. Decisions made before the window closes.
Use Case 44 — Automated Narrative Reporting
The Problem: Finance and ops teams spend days each month writing reports that explain the same patterns in the data in prose form. It is repetitive, slow, and disconnected from higher-value analysis.
The Approach: Natural Language Generation (NLG) models automatically produce narrative summaries from structured metrics, explaining changes, causes, and implications in plain language.
The Outcome: Reports generated in minutes, not days. Consistent quality across every reporting period. Analysts freed to focus on interpretation, strategy, and action.
Use Case 45 — Decision Support & Scenario Simulation
The Problem: Major decisions — pricing changes, market entry, product launches, capacity investments — are made without quantifying the range of likely outcomes.
The Approach: Monte Carlo simulation and optimisation models simulate outcomes under dozens of scenarios, quantify risk ranges, and surface optimal choices with associated probabilities.
The Outcome: Decisions backed by probability distributions, not gut feel alone. Risk is quantified, understood, and manageable before commitment is made.
How to Get Started with Data Science at Your Business
The most common question after seeing this list is: "This sounds powerful, but where do I actually start?"
Here is a practical, honest answer.
Step 1 — Identify Your One Most Painful Decision
Do not try to implement ten use cases at once. Ask yourself: What is the single decision we make repeatedly that we most wish we had better information for? That is your starting point. Pick one. One clear, well-defined problem is worth infinitely more than ten vague aspirations.
Step 2 — Audit What Data You Already Have
Before anything else, understand what data actually exists in your business. Most organisations are surprised to find they already have everything needed for their first model — sitting in their CRM, their e-commerce platform, their accounting system, or their analytics tool. You do not need big data. You need the right data for the specific decision you are trying to improve.
Step 3 — Start Simple and Measure Everything
The first model does not need to be sophisticated. A logistic regression that is 20% better than the current approach is already delivering real business value. Deploy it, measure the outcome, and iterate. Complexity should be earned by demonstrating value — not assumed upfront as a prerequisite.
Step 4 — Build for Decisions, Not Models
The most common failure mode in data science projects is building technically impressive models that nobody uses because they don't fit into how decisions are actually made. Before starting any project, answer one question: How will this output change a decision that someone makes tomorrow? If you can't answer that clearly, redesign the project until you can.
