South Africa’s STEM industries sit at the centre of economic growth, innovation and competitiveness. They shape the technologies, systems and infrastructure that drive business and society forward. Despite the strategic importance of these sectors, women remain underrepresented across technical and leadership roles. This is a leadership, succession planning and economic sustainability issue.
For businesses operating in technology and STEM-driven industries, the challenge is whether businesses are creating environments where capable women can see themselves growing, leading and succeeding over the long term.
According to Lebo Mosola-Mnjama, talent manager at Dariel, representation must become intentional at every level of the organisation. “Businesses should want their workforce to reflect the society they operate in,” she explains. “If women are not represented throughout, particularly in leadership, you lose the opportunity to inspire and motivate the next generation of women entering STEM careers.”
The economic cost of exclusion
The underrepresentation of women in STEM is often framed as a social challenge, but the business implications are just as significant. South Africa continues to face a shortage of critical technical skills across software engineering, cyber security, cloud computing, AI and data science. At the same time, businesses are competing globally for talent while trying to accelerate innovation locally. Limiting participation in STEM fields effectively shrinks the available talent pool in industries already under pressure.
“STEM industries are still considered critical skills sectors in South Africa,” says Mosola-Mnjama. “They play an enormous role in high-value job creation and innovation. Protecting and growing these industries is essential if we want to remain globally competitive.” Research consistently shows that diverse teams outperform homogeneous ones in innovation and problem solving. In technology environments specifically, broader perspectives lead to stronger decision making and more inclusive product development. Gender diversity in STEM is therefore a competitive advantage, and a structural one.
Why the pipeline problem persists
Despite years of discussion around inclusion, many women still view STEM industries as intimidating or inaccessible. Part of this challenge stems from visibility. “When STEM continues to be described as a male-dominated industry, it becomes intimidating for women to pursue these careers,” says Mosola-Mnjama. “Young women need to see that growth, leadership and success in these industries are possible.”
The absence of women in leadership roles often reinforces the perception that technical industries are difficult spaces for long-term career progression. This creates a cycle where fewer women enter the field, fewer stay, and even fewer advance into decision-making positions. Breaking it requires organisations to move beyond surface-level diversity initiatives, and focus on systemic inclusion through clear development pathways, mentorship investment, unbiased hiring and promotion systems and environments where women can contribute confidently and visibly.
“This issue is often over-solutionised,” says Mosola-Mnjama. “Leadership spends too much time discussing ideas and not enough time implementing them. If your workforce does not reflect the country you operate in, then you know where to start.”
Mentorship as a strategic growth tool
One of the most effective ways to strengthen representation in STEM is mentorship. It cannot operate as a passive HR initiative and must become a strategic business function tied directly to succession planning, retention and leadership development. Mosola-Mnjama believes mentorship works best when it reflects the diversity businesses want to create. “A mentor is someone who takes an active interest in another person’s career, challenges assumptions, encourages new ways of thinking and helps build confidence,” she explains. Valuable mentorship can happen across departments, generations and experience levels, and for women entering technical environments, confidence and visibility often matter as much as technical capability.
Retention matters more than recruitment
Many organisations focus heavily on hiring women into STEM roles while overlooking the environments required to keep them there. Retention is where inclusion becomes measurable. Women are more likely to remain in technical careers when businesses pay equitably, offer meaningful growth opportunities, provide leadership exposure, invest in mentorship and create inclusive workplace cultures. “Your company culture should never create an ‘us versus them’ mentality,” says Mosola-Mnjama. “Women need to feel seen, heard and empowered to contribute boldly.”
The leadership responsibility
Building more inclusive STEM industries is a leadership responsibility. Executives, managers and business owners shape the environments where future talent either flourishes or leaves. Every hiring decision, promotion pathway, mentorship opportunity and cultural norm contributes to the long-term makeup of the organisation. For South African businesses, representation should be recognised as an opportunity to unlock broader innovation and sustainable growth.
“The companies that thrive in the future will be the ones that invest intentionally in people,” says Mosola-Mnjama. “Diverse perspectives and inclusive leadership are what drive innovation forward. The future of STEM will be built by the businesses willing to create space for the next generation of diverse leaders to shape it.”
