Nexus SIM Card Inventroy Management Platform

Streamlining customer, site, contract, supply-chain and SIM inventory workflows across one enterprise platform.

Nexus SIM Card Inventroy Management Platform

Project Scope

The Intellica SIM Inventory platform was designed to streamline operations related to customer management, site inventory, contract processing, and network performance tracking. Specifically, the project aimed to simplify the processes of customer onboarding, site management, site survey data entry, customer searches, customer site detail tracking, contract creation, and processing. Additionally, the system was designed to provide a comprehensive, intuitive solution for managing SIM inventory data and contract logistics efficiently, enhancing operational productivity across the enterprise.

A connected operational system, not just an inventory database

The project brought together customer management, site information, site survey data, contracts, supply-chain activity and SIM inventory into one coherent workflow.

  • Business challenge

    Manual and fragmented processes made customer setup, site information, contract handling and inventory administration harder to coordinate.

  • Product opportunity

    Create a central operational platform where information can be entered once, retrieved quickly and carried through connected downstream workflows.

  • Design objective

    Make complex enterprise data entry and processing feel clear, structured and easy to learn for different operational roles.

Users

Designing around operational responsibilities

Stakeholder interviews and workflow mapping were used to clarify the needs of the key roles involved in customer, site and supply-chain operations.

  • Customer service teams

    Create and find customers, review customer details and support onboarding activities.

  • Field technicians

    Capture site information and enter structured site survey results accurately.

  • Supply-chain administrators

    Process contracts, coordinate logistics and manage customer SIM inventory.

Design Process

From fragmented workflows to a single service model

The project began with a thorough analysis of user needs through stakeholder interviews, workflow mapping, and identifying pain points related to manual or fragmented processes. User personas were developed to represent key roles involved, such as customer service teams, field technicians, and supply chain administrators.

This helped clarify the requirements and guide interface decisions. The UX/UI design phase focused on creating clear, straightforward interactions to ensure efficient data entry and retrieval. Wireframes were developed to visualise user journeys, leading to iterative prototyping and usability testing sessions.

Each iteration refined the UI, emphasising ease-of-use, accessibility, and workflow efficiency. The minimalist design reinforced clarity and enabled quick onboarding for new users.

Results

Upon completion, the Intellica SIM Inventory platform significantly enhanced operational efficiency by reducing manual data entry errors and accelerating information retrieval processes. Customer onboarding became streamlined and intuitive, resulting in reduced setup times and improved accuracy. Site data, including detailed survey results, became centrally accessible, improving decision-making processes and site management. The integrated customer search and detail view functionality simplified customer data management, increasing productivity among customer-facing teams. Moreover, creating and processing contracts became more structured and error-proof, substantially improving operational workflows. Overall, the new platform increased transparency, improved operational coordination, and boosted overall productivity and data accuracy within the organisation.

Product structure

  • Customer

  • Site

  • Site Survey

  • Customer Information

  • Contract

  • Process Contract

  • Supply Chain

  • SIM Inventory

Site data structure

  • Customer

  • Site Data

  • Commercial Agreement

Design goals

Reducing operational friction without hiding complexity

The design keeps complex enterprise information visible, but organises it into predictable steps, forms and management views.

  • Reduce errors

    Use structured fields and clear sequencing to make manual entry more reliable.

  • Speed retrieval

    Make customer and site information easier to search and access.

  • Centralise data

    Keep survey, site, contract and inventory information connected.

  • Support hand-offs

    Create clearer transitions between customer service, field and supply-chain work.

Customer & site onboarding

Building the operational record from the start

The early journey establishes the customer and site entities, then captures the detailed survey information needed for later operational and commercial decisions.

Key design decisions

Making complex operations learnable

The visual language stays intentionally restrained. Repeated forms, tables, dialogs and navigation patterns let users concentrate on the data and decisions rather than learning a new interaction model on every screen.

  • Entity-led navigation

    Customer, site, contract and inventory views mirror the underlying business objects and relationships.

  • Progressive workflows

    Large tasks are broken into clear creation, review and processing stages rather than one overloaded form.

  • Context preservation

    Customer and site information remains the anchor as work moves into contracts, logistics and inventory.

  • Structured data entry

    Labels, selectors, forms and modal steps reduce ambiguity and support consistent records.

  • Search before repetition

    Customer search and detail views help teams retrieve existing information instead of recreating it.

  • Minimal enterprise UI

    A simple visual system prioritises clarity, scanability and fast onboarding for operational users.

Iteration & interaction states

Designing the contract flow beyond the happy path

The source design includes multiple contract creation states, demonstrating attention to progressive disclosure, confirmation and the operational details required before processing.
