Stephanie Pretorius, Argon & Co In today’s fast-paced world, businesses and individuals often chase productivity, believing it to be the hallmark of success. However, the relentless pursuit of productivity—defined as the sheer volume of tasks completed—can overshadow a more crucial metric: efficiency. Efficiency, which emphasises the optimal use of resources to achieve desired outcomes, offers a more sustainable and effective path to long-term success. The Lure of Productivity Improving productivity is a common catch cry for many organisations heard from Governments to Boards and CEO’s. Productivity measures how much work is done in a given period. It’s a quantity-focused metric, often leading to a “more is better” mentality. It’s also an internally focussed metric ultimately linked to the sales growth aspirations of most organisations. Productivity growth leads to more output, therefore more sales, therefore more revenue. Who wouldn’t want to grow and improve productivity? However the caveat is: Does productivity lead to higher profitability, financial sustainability and adequate margin? Does it lead higher customer satisfaction that will create a long-term success? In contrast, efficiency measures the quality of the work done – including how well resources, such as time, money, and effort, are utilised to achieve desired outcomes. As a quality-focused metric it prioritises doing things right rather than merely doing more. There are some pitfalls of prioritising productivity alone. Productivity-driven models often ignore process optimisation, resource optimisation and right first time considerations which can inadvertently create higher cost. For example, using overtime to achieve an increase in output can harm profitability but tick the productivity box, or perhaps the production or planning process has not been optimised so more output results in more defects, wasted material or other inefficiencies that already existed. Producing more without regard for optimisation can lead to higher cost and increased waste ultimately harming the […]

Martin Brook, Associate Professor of Applied Geology, University of Auckland, Waipapa Taumata Rau When Resources Minister Shane Jones recently unveiled his draft strategy for mineral mining, it was quickly criticised by the Labour opposition as “taking New Zealand backwards”. One environmental group even called it a “love letter to mining companies”. But the government’s ambition to double the sector’s export value to NZ$2 billion by 2035, with flow-on effects for local employment and regional economies, deserves a broader debate. In particular, New Zealanders opposed to mineral mining must ask whether it is ethically fair and reasonable to effectively outsource the risks of mining to other countries, while benefiting from the modern technologies those minerals make possible. The government’s mining strategy aims to produce a list of “critical minerals” for exploration. The International Energy Agency identifies minerals such as copper, lithium, nickel, cobalt and rare earth elements as essential components in many of today’s rapidly growing clean energy technologies – from wind turbines and electricity networks to electric vehicles. Indeed, according to the United Nations Environment Programme, these critical minerals are increasingly necessary for decarbonising energy systems. One of the three pillars of the draft minerals strategy is the delivery of minerals “for a clean energy transition”. How we source those minerals is an important question. Mount Aspiring National Park: many New Zealanders resist the idea of mining in pristine wilderness areas. Getty Images Environmental impacts of mining New Zealand has a rich mining history, with a wide variety of resources still extracted from underground and opencast mines. There is also a long history of opposition to mining, especially in national parks and on conservation land, as well as on privately owned hill country. And there are legitimate concerns about the environmental, social and governance implications of mining. First, it can have devastating environmental effects, especially the extraction of high-value critical minerals that often require enormous “strip […]
