Global, Green and Information Systems Management

Global, Green and Information Systems Management

This final lecture brings together three dimensions of the future of information systems: how IS is managed as a discipline (Information Systems Management), how global forces shape IS decisions (particularly outsourcing and offshoring), and how digital technology intersects with sustainability and environmental responsibility (Green IT).

Information Systems Management (ISM)

Information Systems Management (ISM) is the discipline concerned with planning, organising, directing, and controlling the IS/IT systems and resources of an organisation as the technology and business environment changes. ISM is not simply IT management — it is the strategic alignment of technology investment and capability with organisational goals.

Key responsibilities of ISM include:

• Portfolio management — managing the full portfolio of IS/IT systems and projects; deciding which to invest in, maintain, upgrade, or retire based on business value and strategic fit
• Human resource management — managing the people within the IS/IT function, including hiring, developing, retaining, and organising IT talent; a critical and often underappreciated ISM responsibility
• Vendor and supplier management — managing relationships with technology vendors, cloud providers, consultancies, and outsourcing partners
• Governance and risk management — establishing policies, controls, and oversight mechanisms to ensure IS/IT is used appropriately, securely, and in compliance with legal and regulatory requirements
• Strategic planning — developing and maintaining IT strategy that aligns with and supports business strategy

Outsourcing: Definition and Evolution

IT outsourcing is the allocation of specific IS/IT business processes or functions to an external specialist service provider. Rather than maintaining all IT capabilities in-house, the organisation contracts with outside providers who deliver those services, typically for a fee.

The primary driver of IT outsourcing from the 1990s onwards was a management goal of costs out — reducing operational costs by transferring IT functions to providers who could achieve economies of scale or access lower-cost labour. Secondary drivers included:

• Access to specialist skills and capabilities not available internally
• Enabling the organisation to focus on its core business rather than IT operations
• Flexibility to scale IT resources up or down as demand changes
• Risk transfer — shifting operational risk to the vendor

Types of Outsourcing

• Selective outsourcing — specific IT functions are outsourced while others are retained in-house; the most common and flexible model
• Full outsourcing — approximately 80% or more of the organisation's IT requirements are supported by an external entity; the organisation retains only governance and strategic oversight
• Offshoring — outsourcing to providers in other countries to access lower-cost labour markets (e.g. software development in India, customer support in the Philippines)
• Nearshoring — outsourcing to a neighbouring or geographically close country, balancing cost savings with proximity and time zone alignment
• Insourcing / Backsourcing — bringing previously outsourced functions back in-house, typically when IT has become strategically critical or when the outsourcing relationship has failed to deliver expected value

When to Reconsider Outsourcing

Outsourcing decisions are not permanent. An organisation should reconsider outsourcing its IT when:

• IT has become core to competitive advantage — differentiating capabilities should not be in the hands of a third party
• The outsourcing vendor is failing to deliver the expected service quality or innovation
• Total cost of outsourcing has risen beyond what in-house delivery would cost
• Strategic flexibility requires direct control over IT capability

Green IT: Digital Technology and Sustainability

Digital technology has a complex and often paradoxical relationship with environmental sustainability. It generates both environmental costs and environmental benefits:

Negative environmental impacts:

• Energy consumption — data centres consume enormous amounts of electricity; global data centre energy use is comparable to that of major countries
• E-waste — electronic waste from discarded devices, components, and infrastructure is one of the fastest-growing waste streams globally; contains hazardous materials
• Carbon footprint — manufacturing, shipping, and operating IT hardware generates significant greenhouse gas emissions
• Water use — many data centres use large quantities of water for cooling

Positive environmental impacts:

• Remote work — enabling remote work reduces commuting emissions and demand for office space
• Digital services replacing physical goods — streaming music and video replaces physical media; digital documents replace paper
• Smart systems — IoT-enabled smart grids, smart buildings, and precision agriculture improve resource efficiency
• Renewable energy for data centres — major cloud providers are increasingly powering operations with renewable energy
• Enabling environmental monitoring — data analytics and satellite technology support climate research and environmental monitoring

The Sustainable Development Goals (SDGs)

The United Nations' Sustainable Development Goals (SDGs) provide a framework of 17 goals addressing global challenges including climate change, inequality, poverty, health, education, and sustainable economic development, to be achieved by 2030. Digital technology is both a tool for achieving the SDGs and a source of risks that the SDGs seek to address.

Information systems professionals and organisations have a responsibility to consider how their decisions contribute to or detract from sustainable development — not just in terms of environmental impact but also in terms of social equity, inclusion, and governance. ISM must increasingly incorporate sustainability thinking alongside technical and commercial considerations.
