Agile software development, Knowledge workers and Lean thinking as a management system

The case lends itself to students of business management, or aspiring consultants, who have been exposed to operations management in general and Lean thinking specifically. It is an advanced case study, assuming prior knowledge in these subjects and approaches the subject matter from an organisational development point of view, rather than a pure operations point of view. It is thus well suited to an elective on operational excellence on an MBA or in executive education courses in Lean thinking

The case starts with Mark, manager of a software development team, hearing that he will have budget for two new developers who will join his team in the coming year. While the extra help could be useful, he was considering what the impact of new people would be on the productivity of the team, which he felt was already stretched. Mark continues to consider the entire development chain and how code changes were implemented to ACSESim’s (the company’s primary product) graphical user interfaces. Having recently been acquired by an American company, he was also under pressure to start to adopt some of the parent company’s systems, which would constitute a fairly disruptive, but necessary, change, particularly for future collaborations with other developers in the parent company. With two new developers, experience taught Mark that development could slow down owing to training efforts. To minimise disruption, he was wondering about how to get the new developers up-to-speed quickly and streamline their operations within a changing corporate environment. The case highlights the different mechanisms that were in place at ACSESim, including the use of issue trackers; Kanban boards; version control software; automated systems; stand-up meetings, etc. Each of these mechanisms is discussed briefly and shows the value they added to the development practices that were in place. This also allows students to understand Agile practices and what Lean thinking might mean in a knowledge work environment and then to consider what the proposed changes might mean and how they could be deployed.

To gain an understanding of how Lean and Agile principles can be applied in a software development environment and Lean knowledge work in general To consider the best way to manage new hires so that they can become productive in a Lean or Agile software development environment, whilst dealing with pressures to migrate to new systems.

SER (Sugar, Energy & Rum) was a company belonging to the Grupo Pellas Corporation. The company operated in four countries, had six subsidiaries, employed more than 25,000 people, had more than 43,500 manzanas of sugarcane crops in Nicaragua alone and had global annual sales of more than US$400m. In 2008, due to the negative effects of the crisis on the company’s business model (increasing costs due to higher prices for fuel and decreasing income because of low international sugar prices), the company decided to implement a business intelligence (BI) system to optimize its processes to reduce costs and increase productivity. At that time, the company had more than 100 years of data, information systems that fed into their main business processes and a culture that appreciated data as the basis for decision-making. However, there were inconsistencies among data systems, users received highly complex reports in Excel or green screens and process monitoring happened long after the tasks had been completed. As a response, SER used extract–transform–load to collect and clean data that would be used in the BI system (the case leaves the questions regarding the systems selection unsolved for discussion). Based on their business model, they selected the most critical processes and defined key performance indicators to measure the impact of changes in those processes. They considered graphic design as a tool to make the system more accepted by users and worked together with users so that reports only offered the most important information. The result was improved costs and productivity. They decreased manual time spent by 14 per cent, automated time spent by 10 per cent, and eliminated 1,556 hours of dead time for equipment in the field, which allowed them to increase productivity by US$1m just in sugar. They saved 20,000 trips from the fields to the factories, which represented more than US$1m in savings by monitoring the weight of wagons loaded with sugarcane in real time. They improved client perceptions about the company both locally and internationally by implementing a sugar traceability system.

The case “Business Intelligence at the Grupo Pellas SER Company” has as its objective to respond to the question: How does a company make its BI system implementation successful? As such, the case: Discusses what a BI system is and what it provides to a business analyses challenges, benefits and context when implementing a BI system; analyses success factors and recommendations in the BI system implementation process; analyses the process of implementing a BI and highlights the importance of the system priority questions and technological alternatives.

Upon completion of the case study, the students will be able to find the challenges and underlying structures that cause the problem; the students will be able to identify the dynamic variables and develop the interconnection and interlinkages among the time-delayed variables to build the story of the business case; the students could develop the block diagram and could build the system dynamics model using the simulation software STELLA, and if they do not have the simulation software, even then they could have a mental model to understand the problem well; the system dynamics students can design the policies to make the system better behaved and recommend solutions; and the students could make mind maps and develop the mental model and could recommend solutions and way forward to overcome the challenges and solve the issues.

Tradeasia is a small-scale manufacturing firm that had started its business activities near Sundar Industrial Estate, Raiwind, in September 2007. The company’s prime focus was to buy the potato starch from chips manufacturing companies and, then, extract the potato starch from the waste potato using its own machinery and sell it as a sizing agent to textile mills. Quality characteristics in terms of better millage and enhanced gullibility made it compatible with Rafhan corn-based starch. The major challenge linked to potato starch was its degree of wetness; the potato starch either extracted from rotten potato or procured from the potato chips manufacturing companies had a high degree of wetness and moisture content. Wet potato starch sometimes had more than 60% moisture content, which was really a challenge. Owing to the high degree of wetness, the wet starch was prone to fungus growth, and within hours, the fungus created toxins if it was not dried immediately, and then after 24 h, toxins acquired a black colour, and they became hardened like pebbles. The starch then was unusable even for sizing purposes for textile products. Reduction in the degree of wetness was really a big challenge and demanded prompt action and high productivity of the operational staff to make that product dry for sale purposes. This was the biggest challenge that ended up in huge inventories of wet starch. Capacity constraints and operational inefficiency killed the company’s productivity and affected the company’s profit.

This case study is written and developed for MBA and MS-level supply chain students of the system dynamics course or those studying management of supply chain complexities. This case study discusses the operational challenges while running the business; huge inventories, capacity constraints and inefficiency in production operations were the challenges associated with almost all manufacturing industries. This case study discussed not only why such challenges are appearing in the business but also the solution that resided in the wisdom shared by the employees in the board meeting. An integrated system dynamics model could be used to design the policies to overcome such challenges. Even the block diagram of the model and causal loop diagram could help to conceptualize the problem and explore the way forward.

Continuous process improvement has been widely taught in business schools and has yielded real results and success in both for-profit and non-profit sectors. Though there have been many cases developed for use in business schools, few, if any, situate the topic in a military context. Further, expeditionary logistics presents managers with special problems of being removed from their supporting enterprise systems that process, track, and/or control of such logistical elements as purchase orders, inventory, distribution, receivables, and fulfillment. The authors present a case in a military setting that exposes students to the challenges of expeditionary logistics and takes them through the fundamentals of process analysis and process improvement.

The authors used a research methodology of a case study. Data were collected during field visits over the course of multiple interviews. Interviews were conducted with subject matter experts and active professionals serving in US Navy expeditionary logistics roles regarding processes and process performance.

This case can be applied to senior undergraduate or graduate-level courses in operations management, supply chain management, or logistics.

The theoretical bases adopted in this paper are supply chain management, information technology, operations management, and process improvement methodologies such as Six Sigma and Lean.

This case reveals that progressive change originated from individual’s positive deviance approaches, opportunistic sensitivity, ability to learn, evaluate and the ability to develop ideas on how to exploit or pursue identified opportunities (intrapreneurial behaviour).

The student will learn to deal with the complex nature of organisations and the tendencies of institutional processes to be uncertain, unpredictable, and uncontrollable; appreciate the internal workings of an organisation, the external environment; and understand the role of generative leadership, positive deviance, novelty ecosystems and intrapreneurial behaviour and the fact that connections and interactions in a social network are non-linear or non-proportional. This means that complex system predictions can be much more than simple regression predictions. They will be able to apply both bottom-up and top-down influences from proactive leadership or generative leadership events and benefit from positive results and the emergence of innovation.

Plymouth Tube, a family business, was a manufacturer of precision tubing and extruded shapes for aerospace, desalination, medical, mining, energy, and water industries globally. Founded in 1924, as of 2012 it employed 770 people at thirteen plants in seven U.S. states and had sales of about $240 million. The family had twenty members across three generations, including spouses. The board was composed of eight members, three from the family and five who were independent. Stacy, age 30, was the only fifth-generation family member working for the company. Her father, Van, age 64 and a fourth-generation member, had been in the business for forty years and had succeeded his father as president, CEO, and chairman.

In early 2013, management presented a very large expansion project that was riskier than previous recent investments to the board, and requested the board's approval. Independent board members asked Van to obtain feedback from the family about the proposal. Van asked Stacy to direct the process for informing the family, asking for their input, and communicating it back to the board.

How should Stacy conduct the process? What should be done with the information once it has been gathered? Should family members be involved in this type of business decision? Based on the information given in the case, is this a good investment?

The learning outcomes focus on enabling students to view operational model changes critically, as they pertain to:

■ evaluating different management styles and uses of the ADKAR change management model in decision-making moments in times of crisis (such as COVID-19) in non-profit organisations (NPOs);

■ evaluating different ways in which NPOs pivot to sustainability, including the use of social enterprise models and change management;

■ anticipating and managing change in institutional formations through new technologies;

■ articulating trade-offs between grant and non-grant resource mobilisation for African philanthropy; and

■ application of change management theory to organisations’ sustainability journeys.

In May 2020, working from her home office just over one month into a nationwide lockdown because of the COVID-19 pandemic, Masego Madzwamuse, chief executive officer (CEO) of the Southern Africa Trust (the Trust), knew that it could once again be at a crossroads. In 2015, the Trust had found itself in a quandary when its primary donor gave notification of its intention to withdraw its funding. The Trust had responded by making changes to its structure and strategy. Now, with uncertainty rife throughout South Africa, the CEO knew that she had to consider whether the changes that had been implemented over the past five years had prepared the Trust not only to respond to, but also to survive the pandemic and continue its vital work long into the future.

This is a case of SmartBay System Integrator (SSI), an IT infrastructure system integrator based in Malaysia, a company that was facing declining profit margins. SSI was reputed to be a well-established locally owned system integrators in the northern region of the country, and the services it provided included building IT systems with high-end servers, networking solutions and software applications. Apart from the urgent need to improve sales, SSI intended to reduce the number of one-off customers and resolve the issue of increasing customer complaints. The complaints given to the company by customers revolved around the sluggish response to customers' requests, including delays in quotations and proposals, constant rescheduling of meeting with customers as well as unfavorable perceptions regarding the competency of SSI engineers. This case requires the analysis of the structure and control systems adopted by SSI to determine whether they are appropriate for the nature of the business and have suitable systems in place to resolve the issue of customer complaints.

This case can be used to teach the use of control systems in managing human resource issues in the context of highly specialised technical professionals in small service firms. In addition, the case also illustrates the need to match an appropriate control system to a specific type of organisational structure. In addition, the case can be relied upon to teach the differences between the various types of organisational structures and the different forms of control systems.
