Overview
This case study looks at how Tiger Brands’ staples and snacks portfolio performs in Gauteng households, with a focus on repeat purchase, cross-category lift, pack-size fit, and promotion quality.
Business Context
Manufacturer portfolios do not grow on brand strength alone. Growth depends on whether core categories hold repeat purchase, whether pack sizes align with household needs, and whether promotions are creating healthy demand rather than short-lived volume.
Problem Statement
Tiger Brands needed a clearer view of which categories, product lines, and pack formats were creating stronger household behaviour, and where portfolio support should go once private-label pressure and margin trade-offs are taken seriously.
Analyst Objective
Build a decision-oriented FMCG portfolio case study that identifies where staples and snacks are contributing to repeat demand, broader household baskets, and the strongest sustainable growth opportunities in Gauteng.
Stakeholders
- Category and commercial teams deciding where the portfolio needs stronger support.
- Consumer-insights teams evaluating how household behaviour differs across staples and snacks.
- Growth teams reviewing where pack architecture and promotions are helping or weakening portfolio quality.
- Leadership teams needing a clearer view of portfolio role beyond topline sales movement.
Key Questions
- Which categories create the strongest repeat purchase?
- Which product lines contribute most to cross-category lift?
- How does pack format change by household size?
- Where are promotions helping demand, and where are they creating weaker trade-offs?
- Which Gauteng opportunities look strongest once repeat strength and commercial quality are read together?
Analysis Logic
- Staples should lead repeat purchase, but not every staple line should behave identically.
- Snacks should show stronger promo sensitivity and broader basket participation.
- Larger households should lean more heavily into family and value packs.
- Cross-category lift should strengthen the best growth opportunities, not just inflate them.
KPI Framework
- Portfolio metrics: value contribution, volume units, average margin.
- Behaviour metrics: repeat purchase rate, cross-category lift, household-size fit.
- Commercial metrics: promo responsiveness, margin change, growth score.
These metrics mattered because the project is meant to support portfolio decisions, not just describe category activity.
Approach
- Built a synthetic transaction-level FMCG dataset across Albany, Jungle, Bakers, Koo, and All Gold.
- Modelled category behaviour across bakery, grains and cereals, snacks, and culinary staples.
- Tested repeat purchase, cross-category lift, pack-size fit, and promotion effects.
- Ranked Gauteng opportunities using repeat strength, basket participation, value contribution, and margin quality.
Insights
- Grains & Cereals is the strongest repeat-purchase category in the final model.
- Bakers is the clearest cross-category connector in the portfolio.
- Larger household formats play a visible role in repeat strength.
- Promotions create useful volume support, but the margin trade-off remains visible by category.
- The strongest Gauteng opportunities sit where repeat demand and basket-broadening behaviour overlap.
Deliverables
- Synthetic FMCG transaction dataset and supporting source tables
- Summary outputs across category, product line, repeat purchase, cross-category lift, promotions, and Gauteng growth
- Exported visuals and Jupyter notebook
- Published standalone project plus embedded portfolio case file
Results
- Overall repeat purchase rate landed at 59.6%.
- Grains & Cereals delivered the strongest repeat-purchase performance.
- Bakers showed the highest cross-category lift in the final model.
- Jungle value pack emerged as the top Gauteng growth opportunity.
Recommendations
- Protect staple categories where repeat demand is strongest and private-label pressure is highest.
- Use family and value packs more deliberately in larger-household growth plans.
- Let snacks broaden the basket, but keep staples as the anchor for household loyalty.
- Treat promotion support carefully in categories where uplift comes with weaker margin quality.
