Chapter Sharing Session on 25 Sep 09

The Chapter held our regular Sharing Session on Friday 25 Sep 09 at ST Kinetics Founders Hall. Our presenters shared with us the following:

  • Updates on Society/Chapter & ISSC/ISSrC with interesting topics, including software safety
    Presented by Siow Seet Ting

Seet Ting, our new President of Singapore Chapter gave an overview of the goals of the System Safety Society and Singapore Chapter. She introduced the new Chapter Executive Committee (Exco) appointed in August 2009. Seet Ting welcomed safety professions to sign up as members of the System Safety Society and as affiliates to the Singapore Chapter. Members and affiliates should also plan ahead to participate in sharing session and the International System Safety Conference.

  • Introduction to GEIA Standard (the commercial MIL-STD-882E)
    Presented by Onn Eng Ling

Eng Ling introduced the much anticipated GEIA-STD-0010, Standard Practice for System Safety Program Development and Execution. She made a comparison between this commercial standard and the MIL-STD-882D. The methodology of system safety is generally the same although there is regrouping of some requirements. She share the developments that lead to the publication of GEIA-STD-0010. As for the popularity of GEIA-STD-0010 henceforth, we will have to wait and see.

  • Certification of Safety Professionals and Joint Weapon Safety Review Process
    Presented by Fan Yue Sang

Yue Sang shared the impetus and benefits of certification of safety professionals. These include recognition of individual achievements and sustainment of competency, self esteem and need for a basis of hiring competent safety professionals. He gave an overview of several certification programs and mooted the possibilities and implications of implementing them locally.

Yue Sang shared the “Lead Service” approach for US safety review of Joint programs. We have a similar risk management framework in the SAF. There was however an additional step of safety endorsement by a technical forum before consideration of risk acceptance in the Singapore context. There is a slight complication in that the technical forum may not be in the same “Service” as the risk acceptance authority.



International System Safety Regional Conference, 2008


The inaugural International System Safety Regional Conference (ISSRC) 2008 was held in Novotel Clarke Quay, Singapore from 23 April to 25 April 2008. The conference was a success both in terms of the technical sessions and in the conference activities. We look forward to have similar events in the region in future.

Sharing Session on 22 May 07

Steve Mattern

More than 60 affiliates attended the sharing session on 22 May 07 held at the DSO National Laboratories. The highlight of the session was Steve Mattern's introduction to guidelines for unmanned systems.

Exco Member Fan Yue Sang gave an introduction to the forthcoming 25th ISSC and the International System Safety Regional Conference (ISSRC 2008) to be held in Singapore in 2008. Yue Sang invited system safety practitioners to freely exchange ideas, comments and issues on their system safety experiences in our future sharing sessions.

The Chapter viewed a recording of Chief Defence Scientist, Prof Lui Pao Chuen's Luncheon Speech to the 24th International System Safety Conference held in Aug 2006. Prof Lui gave the background on the development of the defence in Singapore and decribed how system safety has become an important part of the defence eco-system.

Sharing Session on 1 Nov 06

Our special guest Al
Special guest Al Hartkorn from US
Mr Ronald Tan, ST Aerospace
Mr Lian Tian Tse, DSTA

A sharing session on "Software Safety" was long due as there have been many affiliates had been seeking a baseline of knowledge on this subject. Thanks to our volunteer speakers, we put together a sharing session on 1 Nov 06 on this theme and it commanded a lot of interest.

  • During this session, Fan Yue Sang shared the highlights and key developments at the 24th ISSC. Chief Defence Scientist (MINDEF) gave a luncheon speech and Rodney Tan (DSTA) presented "Safety Culture in Defence" at the conference in Aug 06. Yue Sang also informed of the interesting developments of conducting a "Singapore Track" and "Asia Pacific Track" at the 25th ISSC.
  • Back on the theme and subject of "Software Safety", Ronald Tan (Singapore Technologies Aerospace) gave a clear overview of and motivation for software safety. He identified the approach techniques for software safety and identified the challenges of working with SOUP.
  • Leonard Chia and Roch Cyril (DSTA) skilfully illustrated their presentation of "Developing Safe Software" with their project experience. They highlighted essential steps in software safety and highlighted techniques that work and those that are not effective.
  • Lian Tian Tse (DSTA) delivered a convincing presentation on "Software Safety - Back to Basics". He identified the key role of the DSTA Software QA and Testing is to help software developers identify weaknesses in the software as early as possible so that the developed product would eventually be robust.

There was not a dull moment during this sharing session and indications are that our presenters have conveyed valuable information for people who work with safety critical software. All presenters have shared their presentation materials in the affiliates' area. Log in to view.

Chapter Sharing Session on 11 Jul 06

The Chapter held a sharing session o 11 Jul 06 durng which the current website was launched.

Three topics were shared during this session:

  • Ms Ee Siew Fong of Land Transport Authority (LTA) shared the LTA Hazard Management System with affiliates.  The centralised database was used to track hazards from preliminary hazard analysis (PHA) and the database could be viewed both by staff and management.  The benefit of the shared database is that it provides an updated and consistent safety management information for all levels.
  • Mr Damos from the Singapore Institution of Safety Officers (SISO) conveyed the essence of the new Workplace Safety and Health Act that came into effect on 1 Mar 06.  The principles of the WSHA was to reduce risk at source and promote industy ownership of standards and outcomes.  These principles are consistent with system safety and the topic drew lively discussion during the session.
  • Mr Fan Yue Sang followed on to give a system safety interpretation of the Workplace Safety and Health Act.

Chapter System Safety Seminar held on 10 Feb 06

The Singapore Chapter held a System Safety Seminar on 10 Feb 06 at the auditorium of the Defence Science & Technology Agency (DSTA). The seminar concluded with a networking buffet dinner.

The seminar saw the highest attendance with more than a hundred participants. They were from DSTA, Singapore Technology Engineering Subsidiaries, Ministry of Defence, Defence Science Organisation, Ministry of Manpower, DNV (Singapore), Land Transport Authority and others. During the Q&A time, it was clear that there was substantial interest in software safety and the Chapter President, Mr Michael Tan, suggested that the next sharing session focus on the subject.

The Presenters and the titles of their presentations were:

  • Mr Ron Howlett, UK MoD Defence Procurement Agency on “Safety Management System in the UK MoD.”
  • Ms Audrey Lao, DSTA on her project experience in “Assessing Submarine Explosive Stowage Risks”.
  • Lt Col (Ret) Keith Cook (MBE), System Design Evaluation Ltd (UK) on “Legacy Munition Safety Case Report – Lessons Learned”.
  • Mr Fan Yue Sang, DSTA on “Operationalising System Safety in DSTA”.

System Safety Management Training held 13 Feb 06 to 24 Feb 06

In response to interest from the local defence community, the Singapore Chapter organised two five day System Safety Management Courses in Feb 06 in collaboration with the University of Washington. Sixty participants from DSTA, Ministry of Defence and the local Defence Industry attended the courses.

Participants were pleased with training. In particular, they cited their learning of hazard analysis and application of fault tree analysis. Participants were also grateful for the Steve’s sharing of numerous examples from his experience. The training culminated with the tinker-tanker hands on exercise that brought system safety principles to live.

No one would deny having gone away from the course with a greater clarity of system safety … and everyone enjoyed those entertaining video clips. For members who are still seeking “exercises” that depict systems in their real work, please step forward to offer your systems. In fact, the tinker tanker was brought in to suit participants of earlier courses. Regardless, Steve did not fail to portray the principles & processes of system safety through these exercises, regardless of the example used.
