BBG Global Design System

Unifying webshops to enhance efficiency and consistency

01- Introduction

When I joined Berlin Brands Group in Berlin, I helped spearhead a strategic initiative called the Global Design System (GDS). More than just a rebranding exercise, the GDS aimed to unify multiple webshops under a single, scalable design foundation while preserving each brand’s unique identity. By centralizing essential assets, we planned to increase efficiency, ensure consistency, and enable faster scaling for future brands.


02- Problem Statement

Despite having multiple webshops—Klarstein, Blumfeldt, Electronic Star, among others—each site followed its own design principles. This led to:

  • High development costs: Every new feature was built separately for each brand.
  • Maintenance Bottlenecks: Updates were time-consuming and lacked consistency.
  • Fragmented Brand Experience: Inconsistencies made it challenging to uphold a cohesive look and feel.
  • Inefficient Checkout: A 5-step checkout caused high cart abandonment rates.

Before & After Snapshot

  • Before: Multiple standalone design files, scattered brand elements, and a 5-click checkout.
  • After: Centralized component libraries, consistent branding across 23 shops, and a simplified one-page checkout.

Goals & Objectives

Goal 1:

Reduce cart abandonment from 60% to 30%.

Goal 2:

Provide a standardized design system that cuts dev time for new brands by 30%.

Goal 3:

Improve brand consistency with shared color palettes, typography, and UI components.


03- My Role & Responsibilities

UI/UX Designer

  • Design System Development: Built and maintained the Figma-based system architecture, structuring color shades, typography, and reusable UI components.
  • Prototyping & Testing: Crafted high-fidelity prototypes; ran usability tests to validate design decisions.

Product Owner

  • Project Alignment: Mapped the GDS scope, defined the roadmap, and prioritized tasks using MoSCoW.
  • Team Collaboration: Coordinated with developers, marketing, and product managers for smooth handoffs.
  • Stakeholder Communication: Kept managers and shop owners updated on timelines, requirements, and design rationale.

04- Research & Discovery

Hypotheses

Hypothesis 1:

If we reduce the checkout process from 5 steps to 1, cart abandonment will drop by 20% or more.

Hypothesis 2:

If we adopt a single source of truth (e.g., shared components and tokens), we can lower dev overhead by 20–30% across all shops.

Hypothesis 3:

Aligning visual elements (colors, typography) will boost brand recognition and user trust, reflected in improved returning-user rates.

Research Insights

Stakeholder Interviews:

Identified key pain points in brand consistency and development speed.

Competitor Analysis:

Revealed best practices for e-commerce checkouts, design systems, and performance optimization.

UX Audits:

Confirmed that cart abandonment spiked during multi-step checkouts.

UX Surveys:

Validated earlier findings from stakeholder interviews.

MoSCoW Method

Must-Haves (Essential for MVP):

Unified component library, one-page checkout, thorough documentation, sticky sidebar on product pages, repositioned badges.

Should-Haves (Important but not critical):

SEO-optimized content structure, improved product carousels, Hero banner with 3 key promotions.

Could-Haves (Nice to include if time permits):

Dark mode UI, localization for emerging markets, installment payments, pickup point delivery options, accessibility refinements, live chat support widget.

Won’t-Haves (Not for this version but maybe later):

AR product previews, AI-driven personalization, advanced loyalty program integration (future consideration).

SWOT Analysis

Strengths:

Wide product range, loyal customer base, centralized GDS, faster handoff.

Weaknesses:

Conflicting brand styles, outdated checkout, limited personalization, missing UX features.

Opportunities:

Faster brand rollout, localization & flexibility, accessibility & UX trends, future personalization.

Threats:

Lean competitors, high UX expectations, tech debt risks, localization pressure.

Project Roadmap and Timeline

1. Research & Planning
Duration: 3 months

Competitor analysis, stakeholder interviews, scoping the GDS

2. Design & Development
Duration: 6 months

Building the component library, testing new website templates

3. Testing & Rollout
Duration: 3 months

Implementing GDS across Klarstein, Blumfeldt, and Electronic Star


05- Design Process

GDS as a Blueprint

We structured the Figma-based design system into four foundational layers:

1. Primitives Library:

Core color shade variables shared across all brands.

2. Brand Foundations:

Unique colors, typography, and icons tailored to Klarstein, Blumfeldt, and Electronic Star.

3. Component Library:

A centralized set of reusable UI components for cohesive product layouts.

4. Website Templates:

Quick-start templates developers could adapt for future brands.

Checkout Process Optimization

We replaced the 5-click checkout with a single-page flow, reducing friction and user drop-off.

  • Before: 5-step checkout
  • After: 1-page checkout

Design Tokens

A critical step was exporting design tokens (colors, typography) from Figma into JSON, pushing them to GitHub, and integrating them into SCSS. This approach guaranteed automatic updates whenever a color or style changed in Figma—minimizing manual coding errors and accelerating front-end development.

1. Exporting design tokens

From Figma into JSON files

2. Storing them in a GitHub repository

Where developers could easily access them

3. Integrating tokens into the SCSS web shop

Enabling automatic updates and reducing manual work


06- Key Features and Improvements

  • Hero Banner with 3 Promotions: Boosted conversions by showcasing top deals.
  • Dynamic Recommendation Carousels: Positioned higher on the page for increased visibility.
  • Compacted SEO Content: Improved load speeds and readability.
  • Sticky Sidebar on Product Pages: Streamlined navigation and boosted add-to-cart actions.
  • Repositioned Badges: Emphasized unique selling points near the “Add to Cart” button.
  • One-Page Checkout: Reduced cart abandonment through fewer clicks.

07- Results & Impact

GDS was not merely a redesign—it revolutionized how we handle e-commerce across 23 international webshops. By consolidating design assets, we trimmed design-to-development handoff from 10 days to 7, a 30% reduction measured by sprint data (before vs. after GDS). This holistic foundation cut costs, boosted consistency, and empowered our teams to scale faster and innovate confidently.

Design-to-development handoff improvements

Sprint Pre-GDS (days) Post-GDS (days) Improvement
Sprint 1 10 - -
Sprint 2 9 - -
Sprint 3 8 - -
Sprint 4 - 7 30% (approx.)

Future Focus

We plan to continuously evolve the GDS by integrating emerging UX trends, refining accessibility, and exploring functionalities like installment payments and pickup point deliveries to further optimize the user journey.

08- Key Takeaways

Modular Design Approach:

A flexible structure met various branding requirements while maintaining efficiency.

Cross-Functional Collaboration:

Regular alignment and transparent documentation bridged the gap between design, development, and marketing.

Design Token Implementation:

Translating designs directly into code minimized errors and maintained visual consistency across all webshops.
