About the programme
Course Overview
No single picking method suits every order profile, and warehouses that stay with one method regardless of order size or line count usually leave productivity on the table. This course compares the four core picking strategies in detail: discrete order picking as the baseline, batch picking that groups multiple orders into one pick run, zone picking that assigns pickers to fixed areas, wave picking that releases work in timed groups aligned to shipping schedules, and cluster picking that fills several orders in one pass using cart-based sortation. Participants learn the order profile conditions that favour each method, including line count per order, SKU overlap between orders and required despatch windows, and how to combine methods such as zone plus wave for a facility handling mixed order types. The course covers wave planning against carrier cut-off times, batch sizing to balance pick density against sortation complexity, and the technology, from pick-to-light to voice picking, that supports each method. Exercises use sample order files so participants practise selecting and configuring a picking strategy and calculating expected throughput.
Expected Learning Outcomes
Determine the SKU overlap and line count conditions under which batch or cluster picking outperforms discrete picking.
Design a zone picking layout that assigns pickers to areas balanced by workload and travel distance.
Plan wave release schedules that align picking completion with carrier cut-off and despatch windows.
Size pick batches and cart configurations to balance pick density against downstream sortation complexity.
Match supporting technology, including pick-to-light, voice and RF scanning, to the chosen picking method.
Calculate expected throughput and labour requirement for a proposed picking strategy before implementation.

01Comparing Core Picking Strategies
2 sessions · 8 points
Session 1Discrete, Batch and Cluster Picking
- Define discrete order picking as the baseline method and identify the labour cost it carries at low order density.
- Explain how batch picking groups multiple orders into a single pick run to reduce total travel distance.
- Explain how cluster picking uses multi-position carts to fill several orders concurrently during one pass.
- Compare batch and cluster picking on sortation complexity and the equipment investment each method requires.
Session 2Zone and Wave Picking
- Explain how zone picking assigns pickers to fixed areas and requires a downstream consolidation step.
- Explain how wave picking releases groups of orders on a schedule tied to shipping or carrier cut-off times.
- Identify the operational conditions, such as large facilities or mixed order profiles, that favour zone picking.
- Identify how combining zone and wave picking supports facilities with high SKU counts and tight despatch windows.
02Matching Strategy to Order Profile
2 sessions · 8 points
Session 1Analysing Order Characteristics
- Analyse historical orders for line count, SKU overlap and unit quantity to characterise the order profile.
- Segment order types, such as single-line, multi-line and bulk orders, that may need different picking methods.
- Identify SKU overlap levels high enough to justify batch or cluster picking over discrete picking.
- Assess facility layout and SKU count to judge whether zone picking would reduce or increase total travel.
Session 2Selecting and Combining Methods
- Select a primary picking method for each order segment based on the order profile analysis completed.
- Design a hybrid strategy, such as zone picking with wave release, for facilities with mixed order types.
- Set decision rules that route orders automatically to the appropriate picking method within the warehouse system.
- Pilot a proposed method or combination on a limited zone or shift before full-facility rollout.
03Planning Batches, Waves and Zones
2 sessions · 8 points
Session 1Sizing Batches and Configuring Carts
- Calculate optimal batch size balancing pick density gains against increased sortation and packing complexity.
- Configure multi-position cart layouts for cluster picking to match typical order line counts.
- Set batch release rules that group orders by proximity, carrier or priority to maximise pick efficiency.
- Test batch sizing against a sample of historical order data before applying it operationally.
Session 2Planning Wave Release and Zone Balancing
- Build a wave release schedule that works backward from carrier cut-off times to picking start times.
- Balance workload across picking zones using historical volume data to avoid bottleneck zones.
- Set contingency rules for wave delays caused by system downtime or unexpected volume spikes.
- Coordinate wave timing with labour scheduling to ensure sufficient pickers are available for each wave.
04Enabling Technology and Measuring Performance
2 sessions · 8 points
Session 1Choosing Supporting Technology
- Match pick-to-light, voice picking or RF scanning technology to the chosen picking method and facility layout.
- Assess the accuracy and productivity trade-offs between voice picking and screen-based RF scanning.
- Configure warehouse management system logic to support the selected batch, zone or wave rules.
- Plan technology rollout and picker training alongside the picking strategy change to avoid productivity dips.
Session 2Measuring and Sustaining Throughput Gains
- Calculate lines per hour and orders per hour by method to compare actual against projected throughput.
- Track pick accuracy and mis-pick rates by method to confirm quality has not been traded for speed.
- Review picking strategy performance each peak season and adjust batch size or wave timing accordingly.
- Report throughput and labour productivity gains to operations leadership with method-level detail.
