Agile Systems Engineering - Some views of Robert Halligan, FIE Aust

An interesting paper: “Toward Agile Systems Engineering Processes” by Dr. Richard Turner, of the Systems and Software Consortium, appears in the April 2007 edition of Crosstalk, The Journal of Defense Software Engineering (see

There is much in the paper that I agree with, and some content that I cannot embrace. In the latter respect, most of my disagreements relate to the author’s extreme characterisations of systems engineering – nobody in their right mind would do systems engineering the way the author describes. Certainly, none of PPI’s clients do systems engineering that way!

My other major criticism of the paper is that it fails to acknowledge the (presently) high degree of avoidable rework in most implementations of agile development. The paper stresses the merits of early and frequent delivery of capability usable by the customer/user. In reality, this is sometimes possible, and sometimes valuable. For software, and software-intensive systems, we could replace “sometimes” with “usually”. Conversely, early delivery of capability is sometimes impossible, or sometimes totally without value. A replacement for the bridge that collapsed in Minneapolis is an example of the latter; a control system for a nuclear reactor is another example.

The paper fails to acknowledge that proceeding in ignorance of what is already known about “the problem” is rarely a part of the formula for producing the best outcomes. When the cost of discovering this known information is less than the cost of rework from failing to do so (almost always the case), we waste money and time. In essence, the paper reflects an unawareness of the existence of very effective, low cost techniques for requirements capture and validation – techniques that typically cost only 0.1%-2% of total project cost.

None of the above comment negates the value of agile as one of the primary strategies for system development. When we “engineer the engineering”, agile falls out as the process solution of choice, where it should do so. Similarly, waterfall, iterative, some form of evolutionary development other than agile, or spiral development, falls out, where that alternative will produce the best outcomes, on the balance of probabilities. For larger projects, all of these strategies may well be in effect – hopefully in the right places!

In summary, agile development has emerged as a respectable and entirely proper approach for some types of problem. However, present implementations often involve considerable rework which costs more than avoidance of the rework. I predict that Agile will mature over the next decade towards an optimum balance of requirements capture through exposure of product, and requirements capture and validation through skillful problem analysis.

Developments in Systems Engineering

International Journal of System of Systems Engineering

The International Journal of System of Systems Engineering has published its first edition with the following remit: “IJSSE proposes and fosters discussion on the evolution and current developments in the field of system of systems and systems engineering concepts, with emphasis on the implications of the fact that new developments on technical and non-technical systems are merging. This perspective acknowledges the complexity of the current man-made, ecological as well as societal systems, their interfaces and socioeconomic perspectives, in parallel with different space-time scales, as well as the reflexive characteristic of human systems.”

Systems Engineering Certification – INCOSE and the CSEP

As from 01 July 2008 the International Council on Systems Engineering (INCOSE) has made several changes to its certification programme. In the past the certification exam was based on version 2A of the SE Handbook. Certification also consisted of a single certification, namely Certified Systems Engineering Professional (CSEP).

The programme changes include a progression to version 3.1 of the SE Handbook as basis for the certification exam. Two more certifications have also added, namely Associate Systems Engineering Professional (ACEP) and CSEP for Acquisition (CSEP-Acq).

The ACEP certification is targeted towards junior systems engineers with less than the five years of experience required for the CSEP certification. It uses the same examination as for the CSEP.

The CSEP-Acq has exam questions based on the Defence Acquisition Guidebook (DAG) Chapter 4, in addition to the core CSEP examination.

Detailed information can be obtained on the INCOSE updated certification website.

Education of Youngsters in Systems Thinking

A very interesting flyer recently crossed my desk seeking expressions of interest from educators for a workshop on Systems Thinking in Schools to be held in Australia in January 2009. The workshop is to be run by the Waters Foundation. This expression of interest is to find out whether such an event would be viable outside of the U.S. If you are interested, you can email Ian Marsden at More information on the Waters Foundation can be obtained at

SysML, One Year On

SysML – A History

The Object Management Group (OMG) systems Modeling Language (OMG SysML™) is a general-purpose graphical modeling language intended for specifying, analyzing, designing, and verifying complex systems that may include hardware, software, information, personnel, procedures, and facilities. The language provides graphical representations for modeling system requirements, behavior, structure, and parametrics. SysML represents a subset of UML Version 2 with extensions needed to satisfy the requirements of the UML™ for Systems Engineering RFP. SysML leverages the OMG XML Metadata Interchange (XMI®) to exchange modeling data between tools, and is also intended to be compatible with the evolving ISO 10303-233 systems engineering data interchange standard.

The UML for Systems Engineering RFP was developed jointly by the OMG and the International Council on Systems Engineering (INCOSE) and issued by the OMG in March 2003. The RFP specified the requirements for extending UML to support the needs of the systems engineering community.

Unfortunately, the team which developed SysML fragmented into two warring factions, each developing their version of a language. It is said that one on the factions treated the requirements as for guidance only, whilst the other faction largely ignored the requirements. After intense lobbying by each faction for its version of SysML to be adopted, an intensely difficult process to unify the two competing languages took place.

The Object Management Group announced the adoption of the OMG SysML™ on July 6, 2006 and the availability of OMG SysML™ v1.0 in September 2007. The result has been a language that does not meet the requirements for the language, and a language with which many participants in its sponsorship or development seem to be unhappy.

SysML – The First Year

And so SysML has had its first birthday. What has transpired?

Necessary for the success of any graphical modeling language is software tool support. SysML has performed reasonably well in this respect. Several tool vendors have added support to SysML, mainly in combination with UML:

  • ARTiSAN Software Tools
  • EmbeddedPlus Engineering (Third party for IBM Rational)
  • No Magic
  • Papyrus for SysML (open source eclipse modeling tool)
  • Sparx Systems
  • Telelogic AB Tau and Rhapsody
  • Visual Paradigm, SDE
  • Software Stencils provides Microsoft Visio SysML templates.

OMG SysML is presently subject to a minor update, to V1.1. See This release aims to resolve 36 issues with SysML. The resolution of another 52 issues has been deferred.

There is little evidence of significant take-up by industry of SysML at this time. However, many individuals, enterprises and universities appear to be experimenting with SysML. BAE Systems (UK), is a notable exception regarding industry take-up, having announced a substantial contract with Artisan for supply of SysML software tools.

SysML Web Sites:

  • The SysML Forum is a web community dedicated to the Systems Modeling Language (SysML). The site provides information related to SysML modeling tools, specifications, tutorials, mailing lists, and blogs.
  • The website provides information and specifications related to the Systems Modeling Language (SysML) open source specification project, founded by the SysML Partners in 2003. The SysML specification is publicly available for download, and includes an open source license for distribution and use.

Financial Meltdown and Systems Engineering

US Treasury Secretary Hank Paulson has put a former aerospace engineer in charge of the $US700 billion Wall Street bailout. The bailout is about preventing the credit crisis descending into a full-blown global financial meltdown. Officially, Kasahkari will be interim Assistant-Secretary for Financial Stability in the Treasury.

In the age of exploding hedge funds and disintegrating investment banks, a fundamental capability is to construct and deconstruct the complex mathematical and computer modeling behind the trillions of dollars of mortgage-backed debt and financially engineered derivatives products. According to Paulson, Kashkari is as good as there is, in this respect.

After graduating, Kashkari worked on NASA space missions including the James Webb telescope project before switching to finance and studying for an MBA at the University of Pennsylvania's Wharton School. "The whole idea was to combine engineering with finance," Kashkari's father Chaman Kashkari, also an engineer, said at the time. "He told me the country needed people who have a good concept of engineering and a good concept of finance."

According to Peter Dowd, Executive Dean at the Faculty of Engineering, Computer and Mathematical Sciences and the University of Adelaide, Kashkari's thinking was perfectly understandable.

"It's indicative of the change in engineering to what most people would call systems engineering," Professor Dowd said yesterday.

"The really complex problems we face, be they in the environment or financial or whatever, are interdisciplinary problems that require a systems approach in order not to miss bits of the puzzle.

"Most of what he'll be doing will be mathematical modeling, but if he really wants to embrace it, he'll have to take into account human behavior and the psychology of large groups of people and of individuals. That's when it becomes really interdisciplinary."

Opportunities for Systems Engineering to Contribute to Durability and Damage Tolerance of Hybrid Structures for Airframes

By Jean R. Gebman
The structures making up airframes must be durable and damage tolerant, and the means of ensuring that they have long been well defined for structures made of metal. But a host of new hybrid materials, some of which contain no metal, are now being used, and these can present new damage mechanisms that engineers must address. The Air Force has established a general approach to airframe durability and damage tolerance. The author examines that approach and considers ways it will need to adapt for the new materials. Given the variety of materials, processes, and end uses involved, the engineering effort will necessarily involve multiple specialties. In these circumstances, the tailoring process could benefit from the efforts of systems engineers. The report addresses both technical and programmatic concerns and identifies opportunities for materials and structural engineers to collaborate with systems engineers. Finally, it offers a framework for collaboration.

Sources of Weapon System Cost Growth Analysis of 35 Major Defense Acquisition Programs

By: Joseph G. Bolten, Robert S. Leonard, Mark V. Arena, Obaid Younossi, Jerry M. Sollinger
Previous studies have shown that the Department of Defense (DoD) and the military departments have historically underestimated the cost of new weapon systems. Quantifying cost growth is important, but the larger issue is why cost growth occurs. To address that issue, this analysis uses data from Selected Acquisition Reports to examine 35 mature, but not necessarily complete, major defense acquisition programs similar to the type and complexity of those typically managed by the Air Force. The programs are first examined as a complete set, then Air Force and non-Air Force programs are analyzed separately to determine whether the causes of cost growth in the two groups differ. Four major sources of cost growth were identified: (1) errors in estimation and scheduling, (2) decisions made by the government, (3) financial matters, and (4) miscellaneous sources. Total (development plus procurement) cost growth, when measured as simple averages among the program set, is dominated by decisions, which account for more than two-thirds of the growth. Most decisions-related cost growth involves quantity changes (22 percent), requirements growth (13 percent), and schedule changes (9 percent). Cost estimation (10 percent) is the only large contributor in the errors category. Less than 4 percent of the overall cost growth is due to financial and miscellaneous causes. Because decisions involving changes in requirements, quantities, and production schedules dominate cost growth, program managers, service leadership, and Congress should look for ways to reduce changes in these areas.

Options for Meeting the Maintenance Demands of Active Associate Flying Units

By: John G. Drew, Kristin F. Lynch, James M. Masters, Robert S. Tripp, Charles Robert Roll, Jr.
The methodology developed in this research can be used to quantify and compare the key factors that allow the U.S. Air National Guard to generate peacetime training sorties with a fairly small full-time workforce. The authors apply these insights to proposed Total Force Integration initiatives to evaluate maintenance options for supporting associate units, where the goal of the unit is to produce trained pilots in the most efficient manner possible. The methodology evaluates how various types of personnel can influence the size and productivity of a unit.
