Navigating Software Technical Due Diligence: Key Aspects and 7 Emerging Trends

7 min read

In the dynamic and ever-changing realm of business dealings, the importance of technical due diligence has escalated significantly. As businesses aspire for expansion, ingenuity, and longevity, the imperative to evaluate the technical facets of potential ventures or collaborations has never been more pronounced. Technical due diligence stands as a critical process in managing risks, identifying opportunities, and ensuring the triumph of transactions in today’s intricate business landscape.

Since the enactment of the Securities Act of 1933, due diligence has been indispensable, particularly in M&A transactions. Shockingly, statistics reveal that a staggering 70% of M&A deals fail to realise their anticipated synergies. Within this context, technology due diligence holds a pivotal role in discerning potential synergies between acquirer and target entities. However, studies indicate that a significant portion of M&A transactions fall short of achieving their intended objectives. By meticulously conducting due diligence, organisations can uncover concerns regarding technological compatibility and potential hurdles that could hinder the realisation of synergistic benefits.

Why Technical Due Diligence Matters in Software Systems

In today’s digitally-driven landscape, software systems play a pivotal role in the operations of businesses across industries. However, they also bring forth a host of potential risks and challenges. One such challenge is the prevalence of software failures, which can have profound impacts on business operations and financial outcomes. For instance, a study by Tricentis found that software failures cost the global economy an estimated $1.7 trillion in financial losses in 2021 alone. These failures can result in downtime, disrupting critical processes and services, and leading to productivity losses. Moreover, software inefficiencies, such as slow performance or lack of scalability, can hinder business agility and growth. According to a report by Dynatrace, 74% of organisations experience performance-related issues in their software applications, impacting customer experience and satisfaction.

The consequences of software failures and inefficiencies extend beyond operational disruptions to financial repercussions. Research by the Consortium for IT Software Quality (CISQ) revealed that software defects cost the U.S. economy an estimated $2.84 trillion annually, with each software defect costing an average of $1.13 million to remediate. Furthermore, software security breaches pose significant financial risks, with the average cost of a data breach reaching $4.24 million globally, according to IBM’s Cost of a Data Breach Report.

Given the substantial impact of software failures and inefficiencies on business operations and financial outcomes, conducting technical due diligence specifically for software systems is imperative. By thoroughly assessing the code quality, system architecture, security protocols, and performance scalability of software systems, organisations can identify and mitigate potential risks early in the due diligence process. This proactive approach not only helps safeguard investments but also enhances the likelihood of successful outcomes in software-related transactions. Additionally, technical due diligence enables organisations to align software capabilities with business objectives, optimise resource allocation, and drive innovation, ultimately bolstering their competitive advantage in the market.

Key Aspects of Technical Due Diligence in Software Systems

In the realm of software systems, conducting technical due diligence entails thorough assessments across various key aspects to ensure robustness, reliability, and alignment with business objectives.

Code Quality Assessment

Assessing code quality is paramount as it forms the foundation of software reliability and performance. Poor code quality can lead to a plethora of issues, including bugs, system failures, and maintenance challenges. Code reviews, testing methodologies, and adherence to coding standards are essential practices to maintain high code quality standards, ensuring the stability and longevity of the software system.

System Architecture Evaluation

Evaluating the architecture of software systems is crucial for scalability, performance, and maintainability. Architectural flaws can impede the system’s ability to handle increased workload or adapt to evolving business needs. Assessing the alignment of system architecture with current and future scalability requirements is essential to ensure that the software system can grow seamlessly alongside the organisation.

Security and Compliance Review

Security and compliance assessments are critical components of technical due diligence. Security breaches and non-compliance with regulations can have severe repercussions, including financial losses, reputational damage, and legal penalties. Evaluating security measures, data protection mechanisms, and regulatory adherence helps mitigate risks and ensures that the software system meets industry standards and legal requirements.

Usability and User Experience Analysis

Usability and user experience are integral aspects of software systems, impacting user satisfaction, productivity, and support costs. Poor usability can lead to user frustration and decreased adoption rates. Conducting usability testing and gathering user feedback during the due diligence process enables organisations to identify usability issues early on and prioritise enhancements to optimise the overall user experience.

Now, let’s delve into a specific case study that illustrates how we applied these practices to address the challenges faced by one of our clients, Securly.

Case Study: Transforming FlexTime Manager for Eduspire Solutions (now Securly)

Eduspire Solutions faced a critical need to modernize their product, FlexTime Manager, in order to accommodate high-quantity scaling while maintaining a manageable cost structure. The existing monolith application was struggling with scalability issues, unable to support the increasing user load, which led to stability and performance challenges.

To address this challenge, our team conducted a comprehensive audit of the existing application. Subsequently, we proposed a modern solution leveraging microservice architecture built on cloud-native technologies. This approach allowed for greater flexibility and scalability, addressing the limitations of the monolithic architecture. Additionally, we redesigned the user interface (UI) to enhance user experience and implemented modern frontend frameworks to improve performance and responsiveness. Simultaneously, backend processes were optimized for scalability and efficiency, ensuring seamless operation even under high loads.

The results of our technical and design interventions were remarkable. The transformed FlexTime Manager was now capable of supporting 10x to 100x growth in user base. The application became more resilient, scalable, and cost-effective, aligning perfectly with Eduspire Solutions’ objectives for their digital transformation journey.

This case study serves as a testament to the tangible impact of modern trends in technical due diligence. By adopting innovative solutions and leveraging cutting-edge technologies, we were able to deliver a transformative solution that not only addressed the immediate challenges faced by Eduspire Solutions but also positioned them for future growth and success.

Through such successful case studies, we demonstrate our commitment to helping clients achieve their business objectives and drive success in their digital transformation endeavours.
