3What this role really is

A demand planner forecasts what customers will need, so stock levels match demand. It involves analysing data and working with sales, marketing and operations to keep supply on track.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Microsoft Excel Advanced

You'll be using VLOOKUP/XLOOKUP, Pivot Tables, and SUMIFS almost daily. You should be able to build and troubleshoot basic forecast models, and ideally, have some experience with Power Query for data cleansing.

SAP S/4HANA (IBP Module) or Oracle NetSuite / MS Dynamics 365 Supply Chain Intermediate

You'll be executing transactions, running standard reports, and performing data entry for forecast adjustments within our ERP/SCM system. Understanding how your forecast impacts other modules is a bonus.

Power BI or Tableau Intermediate

You'll use existing dashboards to analyse forecast performance and demand trends. You should be able to create simple reports from clean data sources and understand how to interpret visualisations.

MS Teams or Slack Intermediate

Daily communication with colleagues, sharing files, participating in team channels, and organising quick check-ins. It's how we stay connected and get things done.

R (forecast, tidyverse) or Python (pandas, Prophet) Awareness

You should understand the concepts of statistical programming and be able to interpret output generated by others. If you can write basic scripts for data cleaning or running standard models, that's a huge plus, but not strictly essential from day one.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Forecast Adjustments (Routine) Propose adjustments to supervisor for review and approval. Make independent adjustments within pre-defined thresholds (e.g., +/- 10% of baseline) for assigned products. Escalate anything outside these bounds. Approve adjustments for junior team members. Make significant adjustments based on market intelligence, consulting with Director for major shifts.
Statistical Model Selection Use pre-selected models as instructed. Interpret output under guidance. Choose appropriate model from approved suite (e.g., ARIMA vs. Holt-Winters) based on demand patterns. Consult manager for new model adoption. Design and implement new forecasting models. Define best practices for model selection across the team.
S&OP Input Challenges Gather data to support supervisor in challenging Sales/Marketing inputs. Independently challenge Sales/Marketing inputs with data in Demand Review meetings. Escalate unresolved conflicts to manager. Lead the challenge process in Demand Review. Mediate conflicts between functions to achieve 'one-number' forecast.
Process Improvement Suggestions Identify inefficiencies and suggest improvements to supervisor. Propose and, with manager approval, implement minor process improvements for your own workstream. Lead and implement significant process improvement projects across the demand planning function.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Weighted Mean Absolute Percentage Error (WMAPE)
How far off your forecast is from actual sales, weighted by product volume.
Target · <15% at SKU level, <10% at product family level

If your forecast for 'Product A' was 100 units and actual sales were 110, that's a 10% error. We'll track this across all your products, giving more weight to the big sellers.

Forecast Bias
Whether you're systematically over-forecasting (too much stock) or under-forecasting (not enough stock).
Target · Within +/- 5% at product family level

If your total forecast for your product family was 10,000 units, but actual sales were consistently 9,000 units over three months, you'd have a -10% bias, indicating you're over-forecasting.

Reporting Timeliness & Accuracy
Getting your weekly and monthly forecast reports out on time and with correct data.
Target · 100% on-time delivery with zero data errors

Your weekly forecast update needs to be in the Production team's inbox by Tuesday morning, every week, without fail. Missing a deadline or having a wrong number in there can mess up the whole week's production plan.

Inventory Health Contribution
Your forecast's direct impact on reducing excess or obsolete (E&O) stock for your product lines.
Target · Contribute to a 5% reduction in E&O for assigned categories

By accurately predicting the decline of 'Product B' and adjusting your forecast down early, you helped us avoid ordering an extra 500 units that would have just sat in the warehouse.

Demand Review Meeting Participation
How effectively you present your forecast, defend your numbers with data, and challenge inputs from Sales or Marketing.
  • You're actively asking questions, bringing data to support your points, and aren't just reading numbers off a slide. Other teams listen to your input and respect your perspective, even if they don't always agree.
Cross-functional Collaboration
How well you work with Sales, Marketing, and Production to get a 'one-number' forecast everyone can agree on.
  • Sales and Marketing come to you proactively for forecast insights. You're seen as a helpful partner, not just 'the numbers person'. People feel heard, even if their initial input isn't the final number.
Problem-Solving Initiative
Identifying issues in the planning process or data and proposing practical solutions, rather than just waiting to be told what to do.
  • You spot a recurring data quality issue and suggest a fix. You notice a trend in customer behaviour that impacts demand and bring it to the team's attention with a proposed forecast adjustment.
Documentation & Process Adherence
Keeping our planning processes clear and up-to-date, making it easier for everyone to understand what we're doing.
  • Your forecast assumptions are clearly documented. You follow the established S&OP cycle steps. Someone new to the team could pick up your process notes and understand what's going on.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You enjoy the challenge of taking disparate data points, market intelligence, and historical trends to build a coherent picture of the future. It's like a daily detective job.

Figuring out why sales for a particular product suddenly dipped in the last quarter and adjusting your model accordingly, then seeing the inventory levels stabilise.

Direct Business Impact

You want to see your work make a tangible difference. Your forecast directly drives purchasing, production, and logistics decisions, meaning your efforts have real-world consequences.

Knowing that the production schedule for the next month is based on *your* numbers, and seeing the factory hitting its targets because of it.

Continuous Learning & Improvement

The world of demand planning is always evolving. You're keen to learn new statistical methods, understand market dynamics, and constantly refine your models and processes.

Experimenting with a new forecasting algorithm in Excel or Python to see if you can improve accuracy on a tricky product line, then sharing your findings with the team.

What frustrates people
  • The 'Garbage In, Gospel Out' Problem: You'll be held accountable for forecast accuracy, but sometimes the sales and marketing inputs you're given feel more like wishful thinking than solid data.
  • Data Janitor Duty: Expect to spend a fair chunk of your week cleaning, validating, and reformatting messy POS and shipment data before you can even start the actual analysis. It's not glamorous, but it's essential.
  • Defending Statistics Against 'Gut Feeling': You'll often find yourself explaining to a seasoned sales director why your statistical model is probably more accurate than their 'gut feeling' about a key account. It's an ongoing battle.
  • The Unannounced Promotion: Marketing might launch a major 'Buy-One-Get-One-Free' promotion without giving you enough heads-up, leading to massive stockouts and you getting blamed for a 'bad forecast'. It happens.
  • Month-End Mayhem: The last week of the month usually brings a flurry of 'urgent' requests from finance or sales, forcing you to rework the entire plan, often requiring late nights to hit deadlines. It's just the reality.
What this role does not give you
  • A perfectly predictable, routine workday – expect curveballs.
  • Complete control over all inputs – you'll need to influence, not dictate.
  • Immediate gratification on every project – some improvements take time to show results.
  • A quiet, solitary existence – you'll be talking to people constantly.

8Who you work with

This role directly influences our working capital (how much cash is tied up in stock) and our customer service levels. Get the forecast right, and we're efficient, profitable, and our customers are happy. Get it wrong, and we're losing money on obsolete stock, or worse, losing customers because we can't deliver. You're a critical cog in the machine that keeps our products flowing.

Inside the business
  • Sales Team (Regional Managers)
  • Marketing Team (Product Managers)
  • Production Scheduling
  • Warehouse & Logistics
  • Finance Team (Budgeting & Reporting)
Outside the business
  • Key Retail Partners (for POS data)
  • Suppliers (for lead time discussions)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 2 years of hands-on experience in a demand planning, supply chain analysis, or similar analytical role.
  • Proven ability to work independently on routine data analysis and reporting tasks.
  • Demonstrable experience with advanced Excel functions (VLOOKUPs, Pivot Tables, SUMIFS) and building basic data models.
  • A solid understanding of basic statistical concepts and how to apply them to business problems.
  • Experience collaborating with cross-functional teams, particularly Sales and Marketing, to gather information.
  • A track record of identifying data inconsistencies and proactively seeking solutions.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Data Engineering for Planning

As data volumes grow and we pull from more diverse sources (IoT, external market data), the ability to build robust, automated data pipelines will be crucial. Less time cleaning, more time analysing.

ETL/ELT processes · Data warehousing principles · API integration basics · Data quality monitoring

  • This quarter: Take an online course on SQL for data analysis if you haven't already. It's foundational.
  • Next quarter: Explore Power Query or Python's `pandas` library for more complex data transformations.
  • Month 6: Work with our IT team to understand how our internal data warehouses are structured and how you can access raw data.
  • Month 9: Propose one small automation project to streamline a current manual data prep step.

Quick win: Start using Power Query in Excel to automate one of your recurring data cleaning tasks. It's a powerful tool often underutilised.

Machine Learning for Demand Sensing

Moving beyond traditional statistical models, machine learning can help us pick up on subtle, non-linear demand signals from downstream data (like Point-of-Sale or website traffic) for much shorter-term, more accurate forecasts.

Regression algorithms (e.g., Random Forest, Gradient Boosting) · Feature engineering · Model validation and backtesting · Interpretability of ML models

  • This quarter: Complete an introductory online course on machine learning fundamentals (e.g., Coursera, DataCamp).
  • Next quarter: Experiment with a Python library like `scikit-learn` or `Prophet` to build a simple ML forecast model on a historical dataset.
  • Month 6: Read up on 'demand sensing' concepts and how ML is applied in that space.
  • Month 9: Propose a small pilot project to test an ML model against our current statistical forecast for a specific product.

Quick win: Start by exploring how the 'Prophet' library in Python (or R) can quickly generate robust forecasts, even with complex seasonality. It's surprisingly user-friendly.

11Staying current once you are in

What people here do to keep up
  • Attending industry webinars and conferences on demand planning and S&OP to stay current with best practices.
  • Joining professional groups or online forums to share knowledge and learn from peers in the supply chain community.
  • Taking online courses (e.g., Coursera, edX, DataCamp) to deepen your skills in statistical analysis, Python/R, or data visualisation.
  • Reading relevant books and articles on forecasting methodologies and supply chain trends.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a big chunk of demand planning can feel like repetitive grunt work. But what if you could offload the tedious bits to AI and focus on the really interesting stuff – the strategic thinking, the problem-solving, and the actual insights? That's exactly what we're building towards here at Zavmo.

We're investing heavily in AI tools to supercharge our Operations team. For a Demand Planner, this means less time wrestling with messy data and more time making smarter decisions. We want you to be at the forefront of this, using these tools to make your job more impactful and, frankly, more enjoyable. Think of it as having a super-smart assistant who never sleeps.

Automated Data Harmonisation

Imagine AI automatically cleaning, validating, and standardising all that messy retailer POS data or syndicated market information. It flags anomalies, suggests corrections, and gets your data ready for forecasting in minutes, not hours. No more manual VLOOKUPs trying to match inconsistent product codes!

AI-Powered Driver Identification

Instead of just looking at historical sales, AI models can analyse thousands of variables – weather, social media sentiment, competitor pricing, economic indicators – to spot hidden drivers of demand. It'll suggest adjustments to your baseline forecast, giving you a much richer picture of what's coming.

Intelligent Market Research Synthesis

Ever wish you had time to read every industry report? AI can do it for you. It monitors news, competitor earnings calls, and commodity markets, then delivers a concise daily or weekly brief highlighting key risks and opportunities that could impact your forecast. It's like having a dedicated research assistant.

S&OP Narrative Generation

After you've finalised your forecast, AI can draft the initial commentary for your S&OP presentation. It explains the 'story' of the month – the biggest changes, key assumptions, risks, and opportunities – in clear, business-friendly language. This frees you up to refine, add your insights, and prepare for those tough questions.
