Interdependence With Other Key Business Functions (HSC SSCE Business Studies): Revision Notes
Interdependence With Other Key Business Functions
Introduction
Human resources (HR) does not operate in isolation within a business. Instead, it works closely with all other key business functions to help achieve strategic goals. Understanding these connections is essential for business success.
Interdependence refers to the mutual dependence that key business functions have on one another. HR managers play an integral role in achieving business objectives, just like managers in any other functional area.
The concept of interdependence is fundamental to modern business management. When HR functions effectively connect with finance, marketing, and operations, the entire organisation benefits from improved coordination, better decision-making, and enhanced overall performance.
The importance of interdependence
Some HR managers may not fully recognise how critical their role is in achieving strategic business goals. However, effective HR management directly impacts business performance across all functional areas. When HR policies are well-designed and properly implemented, they create positive outcomes throughout the entire organisation.
The relationship works like a chain reaction: when employees are well-managed and supported, they perform better in their roles. This improved performance flows through to operations, marketing, and finance, ultimately contributing to overall business success. As one Australian business manager noted: "If we take care of our employees they take care of delivering our products, which leaves our customers satisfied which is reflected in our bottom line."
Human resources and finance
The connection between HR and finance is particularly strong because staffing represents a major operational cost for most businesses. However, this relationship extends far beyond simple cost considerations.
Positive financial impacts
An effective HR policy within an organisation creates several financial benefits:
- Profitability gains – Well-managed employees are more productive and contribute more efficiently to the business's outputs
- Share price increases – Investors recognise businesses with strong HR practices as more stable and valuable
- Long-term survival – Businesses that invest in their workforce are more likely to succeed over extended periods
These financial benefits demonstrate that HR expenditure should be viewed as an investment rather than merely a cost. Businesses that treat their workforce as valuable assets consistently outperform those that view employees as expenses to be minimised.
Cost management considerations
In competitive environments, businesses must carefully manage labour costs to maintain financial health. Workers generate income for the business by producing goods and services that customers demand. However, labour expenses must be controlled to ensure profitability.
Australia's relatively high wage rates present significant challenges for businesses competing in global markets. For example, an administrative worker may cost six times more to employ in Australia than in countries like the Philippines. When combined with additional expenses such as superannuation contributions, these costs significantly impact profitability.
Some businesses respond by relocating operations offshore, potentially reducing operational costs by up to 60%, with wages accounting for approximately 20% of those savings. This trend has affected several Australian industries:
- Manufacturing sector – Factory closures and overseas relocations, particularly in automotive manufacturing
- Telecommunications – Companies like Telstra moving some operations offshore
- Banking – Major banks including NAB, Westpac, and ANZ considering offshore options
- Aviation – Qantas exploring overseas operational facilities
While these decisions are primarily financially motivated, they demonstrate how HR decisions directly influence financial performance and strategic direction.
Human resources and marketing
The link between HR and marketing centres on building and maintaining strong customer relationships. When employees are engaged, well-trained, and aligned with the business's values, they become powerful ambassadors for the brand.
Employee impact on customer relationships
Marketing success depends heavily on employees who interact with customers. These staff members must embody the brand's values and deliver consistent, high-quality service. This creates enduring relationships between the business and its customers.
Businesses that invest in their workforce see several marketing benefits:
- Employees who genuinely understand and believe in products or services
- Authentic customer interactions based on real experience and knowledge
- Consistent brand delivery across all customer touchpoints
- Positive word-of-mouth from satisfied, engaged employees
Case study: Kathmandu
Case Study: Kathmandu's HR-Marketing Integration
Kathmandu provides an excellent example of HR-marketing interdependence. The outdoor equipment retailer's marketing approach focuses on consolidating its reputation as an inspirational, iconic brand synonymous with adventure, innovation, and passion. Its core purpose is to "inspire and equip the adventurer in everyone."
To achieve this marketing goal, Kathmandu's HR strategy includes:
- Values alignment – Recruiting employees who share the company's environmentally sustainable approach
- Skills development – Providing comprehensive induction processes and regular training sessions
- Financial incentives – Offering generous rewards to retain talented staff
- Career pathways – Encouraging employees to pursue customer-focused, long-term retail careers
The Result: Customer sales representatives can authentically endorse Kathmandu's brand philosophy, delivering the best customer experience with genuine, experience-based service. Employees aren't just selling products; they're sharing their own passion for outdoor adventure.
Human resources and operations
The operations function relies heavily on HR management to ensure efficient production of goods and services. Businesses that invest strongly in the relationship between management and employees typically see more efficient and committed contributions to operational processes.
Productivity improvements
There is a positive correlation between HR initiatives and operational productivity. When businesses implement concerted efforts to improve:
- Employee training and development opportunities – Workers become more skilled and capable
- Rewards and recognition systems – Employees feel valued and motivated to perform well
- Workplace wellbeing – Staff are healthier, happier, and more productive
These HR investments translate directly into operational benefits such as higher output, better quality products, fewer errors, and more efficient processes.
Case study: Bank of Queensland
Case Study: Bank of Queensland's Operational Excellence through HR
The Bank of Queensland demonstrates the operations-HR connection through its approach to corporate social responsibility. The bank recognises that a harmonious work environment is integral to business success.
Key HR practices that support operational excellence include:
- Diversity management – Branch staff reflect the multicultural character of Australia, helping serve diverse customers effectively
- Fair recruitment – Equitable selection processes ensure the best candidates are hired
- Employee support – Confidential counselling services help staff manage personal and professional challenges
- Professional development – Ongoing learning opportunities keep staff skills current
- Flexible arrangements – Part-time, work-from-home, and job-share options accommodate different employee needs
- Additional benefits – Health information, loan discounts, and travel benefits enhance employee satisfaction
The Outcome: By supporting employees through these initiatives, the Bank of Queensland creates operational efficiency. Staff members are more engaged, knowledgeable, and capable of delivering excellent service to customers.
Responsibilities of specialist human resource managers
In larger businesses, specialist HR managers or teams handle human resource management functions. These professionals are typically responsible for seven key areas:
Understanding these seven key areas is essential for comprehending the full scope of HR management in modern organisations. Each area requires specific expertise and contributes to overall business performance.
1. Human resource planning and job design
This involves forecasting workforce needs and structuring roles effectively. HR managers must anticipate how many employees will be needed, what skills they should possess, and how jobs should be organised to maximise efficiency and satisfaction.
2. Acquisition: recruitment, selection and placement
HR managers oversee the process of attracting, evaluating, and hiring new employees. This includes developing job advertisements, screening applications, conducting interviews, and placing successful candidates in appropriate roles.
3. Development: induction, training, career development and performance appraisal
Once employees join the business, HR manages their ongoing development through:
- Initial orientation programmes (induction)
- Skills training to improve job performance
- Career planning and advancement opportunities
- Regular performance reviews and feedback
4. Maintenance of staff: wellbeing, legal responsibilities and communication
HR ensures employees remain satisfied, healthy, and legally protected. This includes managing workplace health and safety, ensuring compliance with employment legislation, and facilitating effective communication throughout the organisation.
5. Performance management and rewards
HR managers develop systems to measure employee performance and provide appropriate compensation. This includes designing salary structures, bonus schemes, and other incentives that motivate staff and recognise contributions.
6. Separation
When employees leave the business (through resignation, retirement, or termination), HR manages the exit process. This includes conducting exit interviews, ensuring legal compliance, and managing knowledge transfer.
7. Managing diversity
HR implements policies that promote gender equity and prevent discrimination. This includes ensuring compliance with anti-discrimination legislation and creating inclusive workplace cultures that value different backgrounds, perspectives, and experiences.
Emerging responsibilities
Specialist HR managers are increasingly involved in:
- Negotiations with trade unions
- Establishing and negotiating enterprise agreements
- Preparing for industrial relations tribunals
These responsibilities reflect the evolving nature of workplace relations and the growing complexity of employment law. Modern HR managers must stay current with legislative changes and industry developments to effectively manage these emerging challenges.
Strategic role of human resources
When the HR manager is part of the senior executive team, their role extends beyond operational HR functions to strategic business decision-making.
Strategic involvement
Senior HR executives collaborate on major business decisions including:
- Changes to products or services offered
- Reorganisation of work structures and processes
- Business expansion or contraction
- Mergers and acquisitions
- Organisational culture development
Strategic planning requirements
Critical Strategic Capabilities
The strategic HR role increasingly requires awareness of:
- Global trends – Understanding international labour markets and employment practices
- Labour market issues – Monitoring skills shortages, wage pressures, and demographic changes
- Industrial relations policies – Staying current with employment law and union activities
- Risk management strategies – Identifying and mitigating people-related business risks
- Organisational auditing – Evaluating workforce effectiveness and efficiency
Without this broader business awareness, HR managers cannot effectively contribute to strategic decision-making or anticipate challenges that may impact workforce planning.
From strategy to operations
A key function of senior HR managers is developing strategic HR plans that align with overall business strategy. These strategic plans must then be translated into operational plans that guide day-to-day HR activities throughout the organisation.
This translation ensures that broad strategic objectives (such as "become an employer of choice") are broken down into specific, actionable initiatives (such as implementing flexible working arrangements or enhancing training programmes).
Case study: Google's people-first approach
Case Study: Google's People Operations Excellence
Google provides an outstanding example of how HR drives overall business success. At Google, HR is called "People Operations" (POps), reflecting its central role in business growth and development.
Google's HR Philosophy
The People Operations team operates with the mantra: "find them, grow them, keep them." This philosophy emphasises:
- Finding talent – Attracting the curious and creative colleagues who fit Google's culture
- Growing talent – Providing development opportunities that help employees reach their potential
- Keeping talent – Creating an environment where people want to stay long-term
Cultural Impact
Google's workplace promotes:
- Strong staff involvement – Employees contribute ideas and influence decisions
- High engagement levels – Workers feel connected to the company's purpose
- Common purpose – Everyone understands and embraces company vision and goals
- Interaction and innovation – Workplace design encourages staff to collaborate, often resulting in new product ideas
Business Outcomes
This people-first culture has delivered impressive results:
- Google ranks in the top 50 of the world's global companies
- The company is recognised as one of the best employers globally
- Employee satisfaction drives innovation, which drives business success
Key Lesson: Google demonstrates that managing the links between HR and other functional areas creates synergy that ultimately delivers business success.
Best practice examples
Leading companies invest heavily in attracting and developing the best workforce. Organisations currently considered the best in the world at managing employees include Apple, Google, Facebook, Coca-Cola, Deloitte, AT&T, Marriott International, LinkedIn, Goldman Sachs, and Twitter.
What Sets These Companies Apart
These businesses share common characteristics:
- Commitment to measuring HR effectiveness through Key Performance Indicators (KPIs)
- HR metrics that rank equally with financial performance indicators
- Regular evaluation and reporting on HR outcomes
- Willingness to act on results and continuously improve practices
This approach reflects recognition that people are a business's most valuable asset, and managing them effectively is as important as managing finances or operations.
