Key Quality Attributes for Digital Startups

Discover the critical aspects of software development with insights from Nataliia P. , Head of Customer Engagement & External Operations at Django Stars. This article dives into how foundational system quality attributes such as scalability, security, and usability are integral for developing robust digital products. It’s a must-read for founders aiming to enhance their software's architecture and ensure its long-term success.


Making the right strategic decisions early in the development process is crucial for software startups aiming to create standout digital products. By prioritizing effectively from the beginning, a project can maintain its focus on strategic metrics and avoid unnecessary costs.

In this article, I aim to equip founders with a robust understanding of product quality attributes — often referred to as 'ilities' due to the common suffix many of these terms share. Leveraging insights from my experiences with Django Stars, a technical partner to businesses since 2008, I will highlight essential "ilities" and offer practical industry examples.

The Role of Quality Attributes in Product Development

In systems engineering, non-functional requirements (NFRs) set criteria for evaluating a system's operation rather than its specific behaviors. Unlike functional requirements, which dictate what a system must do, NFRs outline how the system should operate, focusing on attributes such as security, usability, performance, and scalability. Often termed "architectural characteristics" in software architecture, NFRs can be categorized into execution qualities (observable at runtime) and evolution qualities (pertaining to the system's static structure). Specifying NFRs in measurable terms is paramount crucial, as they determine the system's overall success.

Quality attributes, or "ilities," are realized NFRs used to evaluate a system's performance. These architecturally significant requirements demand careful attention to ensure alignment with both business and user needs. For instance, synchronous communication between software components requires shared architectural characteristics, underscoring the interdependence within system infrastructure.

Let's take a look at the key attributes startup founders need to understand enhancing? their product’s market readiness and operational effectiveness.

Stage of development when the respective attribute should be added to the product.

1. Scalability: The Growth Enabler

Scalability ensures that software can handle increased loads over time without compromising performance. Addressed during the early startup stages, it prevents performance bottlenecks, ensuring user satisfaction and business growth.

Examples (based exclusively on personal assumptions):

  • Fintech: A payment gateway like Stripe handling a spike in transactions during Black Friday sales.
  • E-commerce: An online retailer like Amazon managing increased traffic and orders during peak shopping seasons.
  • Healthcare: An electronic health record (EHR) system scaling to accommodate a growing number of patient records or in case of epidemics (e.g., COVID-19).
  • Logistics: A logistics platform like DHL's tracking system managing increased parcel volume during holiday seasons.
  • Ed-tech: An online learning platform like Coursera handling increased enrollments during peak academic seasons.

Ignoring scalability can result in performance degradation and downtime during peak periods, potentially leading to customer loss and reduced revenue. However, in cases where the startup product is designed for minimal, controlled usage without plans for rapid expansion, prioritizing scalability may not be necessary. This allows developers to concentrate on more immediate priorities in the early development stages.

2. Maintainability: Simplifying Evolution

The startup product must evolve to meet changing needs, and maintainability refers to the ease with which software can be modified, updated, or enhanced. Prioritizing maintainability during the product design, development, and maintenance stages reduces both time and costs associated with fixing bugs, adding features, and making improvements.?

Examples (based exclusively on personal assumptions):

  • Fintech: Updating compliance features in a banking app to meet new regulations.
  • E-commerce: Adding new product categories and features to an e-commerce platform like Shopify.
  • Healthcare: Updating a medical records system to include new health protocols and data formats.
  • Logistics: Enhancing route optimization algorithms in a logistics software to adapt to new delivery zones.
  • Ed-tech: Adding new course formats and features to an online education platform like Khan Academy.

Overlooking this attribute in a startup can lead to going over budget — due to high maintenance costs, complications in software updates, increased bugs, and the buildup of technical debt. However, if the startup? product is designed for short-term use or initial testing phases, maintainability may not be immediately crucial, allowing teams to focus resources on more pressing needs in the early stages.

3. Security: Safeguarding Digital Assets

Security in software development encompasses the protection of systems against unauthorized access and vulnerabilities. For a startup, security oversights can be a dealbreaker during a technical due diligence audit for an investment round, IPO, or M&A.

Examples (based exclusively on personal assumptions):

  • Fintech: Implementing end-to-end encryption for transactions in a digital wallet app.
  • E-commerce: Securing customer data and payment information on an e-commerce website like eBay.
  • Healthcare: Ensuring patient data privacy in a telemedicine app through HIPAA compliance.
  • Logistics: Protecting shipment data and customer information in a logistics system from unauthorized access.
  • Ed-tech: Securing student data and preventing unauthorized access in an online learning management system (LMS).

This attribute is vital at all stages — from product design through development to maintenance — to prevent data breaches and legal liabilities, protect sensitive information, and maintain user trust. Neglecting security could be justified if the startup product does not handle sensitive data and operates in a secure, isolated environment, though this is rarely advisable given the potential risks.

4. Performance: Enhancing User Experience

The performance of the startup product software is closely linked to the efficiency and speed with which tasks are executed. Although some projects might allow for occasional bugs or crashes (for example, during quick demonstrations or initial testing), high-performing software offers a smooth and responsive user experience, essential for user satisfaction and productivity.?

Examples (based exclusively on personal assumptions):

  • Fintech: Fast transaction processing in a stock trading app like Robinhood to execute trades in real-time.
  • E-commerce: Quick loading times and smooth navigation on an e-commerce site like Zalando.
  • Healthcare: Fast retrieval and update of patient records in a hospital management system.
  • Logistics: Efficient processing of shipment tracking updates and route calculations in real-time.
  • Ed-tech: Quick access to course materials and seamless video streaming on an educational platform like edX.

Poor performance poses risks of slow response times, user frustration, and potential loss of business. However, in some startup scenarios where basic functionality takes precedence, high performance may not be as critical initially (though it often becomes more important as the product evolves and user expectations grow).

5. Usability: The User-Friendly Focus

Usability ensures that the startup product ?software is user-friendly and intuitive, which is essential for fostering user satisfaction and adoption. This aspect is generally addressed during the design and development phases.?

Examples (based exclusively on personal assumptions):

  • Fintech: An intuitive interface for budgeting tools in a personal finance app like Mint.
  • E-commerce: A user-friendly checkout process in an online store like Etsy.
  • Healthcare: Easy-to-navigate interfaces for patient portals in healthcare systems like MyChart.
  • Logistics: User-friendly dashboard for managing deliveries and tracking shipments in a logistics platform.
  • Ed-tech: Intuitive interface for students and teachers on an ed-tech platform like Google Classroom.

Neglecting usability, a startup is at risk of low user adoption, high error rates, and a negative user experience. Occasionally, usability may be deprioritized when the focus is on showcasing core functionalities rather than optimizing the user interface, especially in the early prototypes or MVPs (Minimum Viable Products).

6. Portability: Flexibility Across Platforms

Portability allows the? startup? product to run on various platforms and environments, expanding its reach and accessibility. Considerations for portability ensure that the product can adapt to different devices and operating systems.?

Examples (based exclusively on personal assumptions):

  • Fintech: A mobile banking app like Revolut available on both Android and iOS.
  • E-commerce: An e-commerce platform like Shopify that works on mobile, desktop, and tablets.
  • Healthcare: A telehealth platform like Teladoc that runs on smartphones, tablets, and computers.
  • Logistics: A mobile app for logistics management that works across different devices and operating systems.
  • Ed-tech: An educational app available on multiple devices, enhancing accessibility for students.

With insufficient portability, the risks for startups include a limited user base, lower adoption rates, and potential loss of market share. However, in cases where the software is intended to operate within a specific environment, the need for portability may be reduced.

7. Modularity: Structured Efficiency

Modularity refers to the division of startup product into distinct, interchangeable components, which facilitates easier maintenance, testing, and reuse of these components. This approach is integral during the software design and architecture stages to improve overall development efficiency.?

Examples (based exclusively on personal assumptions):

  • Fintech: Modular architecture in a blockchain platform to add new features like smart contracts.
  • E-commerce: Using microservices in an online marketplace like eBay to handle product listings, orders, and payments independently.
  • Healthcare: Implementing modular EHR systems to manage different departments such as radiology, lab results, and patient records separately.
  • Logistics: Modular system in logistics software allowing easy updates and integration of new features.
  • Ed-tech: Modular System design in an ed-tech platform enabling easy addition of new course modules and features.

Modularity prevents such risks as difficult and costly updates, higher risk of bugs, and reduced development efficiency. Yet, it may be less of a priority in startup projects where code organization is secondary to rapid development and monolithic code is acceptable.

8. Interoperability: Seamless Integration

Interoperability ensures that the startup product can seamlessly work with other systems and software, enhancing functionality and user experience. This is a significant consideration during the software design and development stages.?

Examples (based exclusively on personal assumptions):

  • Fintech: Integrating an investment platform with various banks for seamless fund transfers.
  • E-commerce: Connecting an e-commerce site with inventory management and shipping systems like Shopify's integrations.
  • Healthcare: Integrating a health information exchange (HIE) with multiple hospital systems for unified patient records.
  • Logistics: Integration of logistics software with various carriers and ERP systems for seamless operations.
  • Ed-tech: Seamless integration with various educational tools and platforms, enhancing learning experiences.

Interoperability helps software avoid reduced functionality, lower user satisfaction, and potential data silos. However, for startup products that do not require integration with other systems, the emphasis on interoperability may be minimal.

9. Compliance: Meeting Standards

Compliance with legal, regulatory, and industry standards ensures that the startup product adheres to relevant guidelines, avoiding potential fines and safeguarding user data. This is crucial during software design, development, and maintenance.?

Examples (based exclusively on personal assumptions):

  • Fintech: Ensuring a fintech app complies with GDPR for European users.
  • E-commerce: Adhering to PCI DSS standards for handling credit card transactions on an online store.
  • Healthcare: Meeting HIPAA requirements for storing and transmitting patient data in healthcare software.
  • Logistics: Compliance with international shipping regulations and data protection laws in logistics software.
  • Ed-tech: Adhering to FERPA regulations in an educational platform ensuring student data privacy.

Neglecting compliance? poses risks of legal penalties, loss of user trust, and potential business shutdown. However, for the startup product that will not reach production or face public release, compliance may be a lesser concern initially.

Conclusion: Embracing Quality for Success

The deep understanding and implementation of these quality attributes are not merely a checklist for compliance but a strategy for achieving excellence in software development. These attributes form the cornerstone of a resilient software product, preparing startups to meet future challenges and user expectations effectively.?
