Chapter Meetings (Western Cape)

A vision to host INCOSE international events in South Africa was met with some scepticism at the 2009 INCOSE International Symposium in Singapore (IS2009). Undeterred, the vision was pursued with determination, resulting in the INCOSE SA Chapter hosting the first ever EMEA Systems Engineering Conference on the African continent in Somerset West in 2014 EMEASEC2014). The huge success of the conference, and continued promotion at international INCOSE events resulted in INCOSE Board approval, in April 2018, to host IS2020 in Cape Town. Having landed the coveted flagship event, the South Africa Chapter is now faced with the challenge to support the INCOSE Events Committee to ensure that IS2020 goes down in INCOSE annals as a most memorable and successful event. The participation of our South African members is important, hence we present a short tutorial to kick-start preparations for IS 2020 paper submissions. The following will be covered in the tutorial:

• What is the role of a paper in a profession?

• What is the difference between a presentation, a conference paper, and a journal paper?

• The double-blind paper review process determines the quality of a paper.

• System engineering is a social science and demands social science research.

• Who should write a paper? What’s in it for the author?

For over ten years, the systems engineering community has focused on transforming from document-centric to model-based techniques. But the challenge is not to transform systems engineering. The challenge is to transform the holistic engineering lifecycle. How must we evolve model-based systems engineering to enable the digital future?

For 25 years, David Long has focused on helping organisations increase their systems engineering proficiency while simultaneously working to advance the state of the art across the community. David is the founder and president of Vitech Corporation, where he developed CORE™, a leading systems engineering software environment. He co-authored A Primer for Model-Based Systems Engineering, and is a frequent presenter at industry events around the world. A committed member of the systems community and ESEP, David is the immediate past president INCOSE.

The Specification Tree is a well-known artefact for system engineering; but for many purposes its resolution is not nearly fine-grained enough. The Requirement Tree has the resolution of individual requirements and individual characteristics, and proves to be a very useful artefact as will be discussed.

The talk will showcase a collection of peer-reviewed articles by promising young scientists and their academic mentors. The research is contextualized by South Africa’s multi-year investment framework in research and capacity development for systems analysis through the NRF and the Department of Science and Technology (DST). This seminal publication serves as a valuable resource for policy makers, researchers and postgraduate students; providing tools and an analytical foundation for the management and governance of natural resources, disasters, and climate change for the technological and ecological transitions to sustainability. The book, edited by Priscilla Mensah (NRF), David Katerere (TUT), Sepo Hachigonta (NRF) and Andreas Roodt (UFS):

• Serves as a valuable resource for policy makers and also postgraduate students conducting research using systems analysis thinking.

• Provides an analytical foundation for the management and governance of natural resources, disasters, and climate change

• Includes scientific and strategic analysis to better understand the dynamics of future energy transitions, their main driving forces, enabling factors, barriers, as well as their consequences

The current draft version of South Africa's Integrated Resource Plan (IRP 2016 Draft) plans for a renewable energy share in domestic electricity production of 18% by 2030, 26% by 2040 and keeps that share constant at 26% until 2050. The plan limits the amount of renewables that can be built in any given year and therefore arrives at these relatively modest renewables shares until 2050. The CSIR conducted a study that lifts the renewables new-build constraints and re-optimises the power mix until 2050 from a pure least-cost perspective. The preliminary results of this unconstrained model outcome will be presented. The least cost scenario exhibits a large amount of solar PV and wind in the power system by 2050. With a much larger share of these two variable renewables (VRE) in the power system, the immediate next question is how to bring in the concept of sector coupling (electricity, transport and heat) in order to reduce total energy system cost even further (through the portfolio effect) and in order to de-carbonise and de-risk the transport sector (through reduced liquid fuel consumption and imports). The principal outline of such a fully integrated energy sector based on electricity as the new primary energy source will be outlined. About our speaker:

Work Breakdown Structure (WBS) can be a powerful aid in effectively managing projects, but it is also easily misunderstood and misapplied. Issues to be considered include: why WBS must not be just a breakdown of work, essential principles in adopting WBS as a management tool, failsafe rules for constructing effective WBS, relationships to other structures useful in project/engineering management, e.g. Systems Breakdown Structure (SBS), Cost Breakdown Structure (CBS), Organisational Breakdown Structure (OBS), Specification Breakdown Structure (Specification Tree), application of WBS to costing, scheduling, definition, risk analysis, measurement, reporting, organisational design, and control.

The development of an organization is a complex process: as a continuously changing organism, it is confined to a structure created in a continuously changing environment. This talk aims to give a broad and philosophical overview of the essential aspects of such an organism: the environment (legalities, paradigms and algorithms); the people in the organisation, planning for the future making use of opportunities and threats in uncertainty; and the structural aspects ensuring a proper fit for the organisation. Dr Willem Barnard obtained a DSc at the University of Pretoria in 1977. From 1969 – 1991 he had several positions in engineering, research and management in high technology sectors. In 1992 he became the managing director for Dorbyl. In 1994 he was appointed the Chief Executive Officer for KWV and held that position until 2007.

Since then he is the Executive Chair for Vastech. Dr Barnard served on numerous boards and played a major role in establishing the importance of systems engineering and other technological capabilities for South Africa.

Despite technological advances seen in the past decades, several best practices for developing usable user interfaces are still too seldom being applied. Yet, the user interface of a software system is often its most complex and volatile component, where most of the problems in the end converge.

While agile approaches aim at delivering often high quality batches of the system, they also run the risk of overseeing problems with the design of the user interface. To many people, the user interface is just a thin layer of coat covering the underlying system. But this is not true in the majority of cases: users will rebel against such user interfaces, leading to low productivity, low acceptance, too many errors, refusal to learn to use new features, boycott of the system, etc.

In this talk we will see how agile approaches that strive to make the software development process controllable can be coupled to usage-centred development practices so that usable software can be delivered in time and with the expected quality.

Giorgio Brajnik is Associate Professor at the University of Udine, Italy, where he teaches usage-centred development of web sites and object oriented programming. Recently he cofounded Interaction Design Solutions, a spinoff company specialized in software quality and automated testing methods; it helps software companies to produce better software.

For almost ten years, the systems engineering community has been focused on the transformation from document-centric to model-based techniques. While most systems engineering organizations have completed pilot efforts, established appropriate communities of practice, and are plotting their path forward, this transformation is far from complete. In terms of the Roger’s innovation adoption lifecycle, we are beyond the early adopters, in the early majority, and moving towards the tipping point where model-based systems engineering becomes the expected framework and approach for systems engineering.

Systems engineering remains a young discipline – one that must continue to learn and evolve, one where transitions should be viewed as waypoints along a journey rather than destinations themselves. While work remains to ensure the transformation to model-based techniques is both efficient and effective, it is time for the systems engineering community to begin looking beyond MBSE. When model-based is simply the way organizations practice systems engineering, what is the next evolution required to address next generation problems and deliver the organizational value required? How must the systems engineering practice evolve? What can we begin doing today – even in the continued implementation and adoption of MBSE – to prepare ourselves and our organizations to make that transition? Looking at the journey to date and the opportunities in the future, how can we characterize the next leg of the journey and plot a path forward for ourselves, our organizations, and the greater systems engineering practice? For over twenty years, David Long has focused on helping organizations increase their systems engineering proficiency while simultaneously working to advance the state of the art across the community. David is the founder and president of Vitech Corporation where he developed CORE®, a leading systems engineering software environment.
