CommentStreams:39f8b0875db2ee2976a87701ab901cfd System Safety Is this it safety is a vital attribute - and there is a lot of SE literature showing how to design for it. This article seems extremely brief and perfunctory. Need to describe the impact of safety (eg ARP 4754A looking at the way to manage traceability, and how rigorous that has to be be based on the safety impact of the item in question anonymous Nov 21 at 10:36 pm
CommentStreams:23f81dc02e81c3c7838235a695739112 Product Systems Engineering Key Aspects Difference between needs and requirements near the start of article, it says "an acquirer specifies the needs and requirements" - an acquirer is one of several stakeholders - they totally have needs, but they only become requirements when the systems engineer of the solution has integrated these needs with the needs of other stakeholders, analysed then understood and then completed (stakeholders don't know everything they want) and so produced a valid set of requirements for the system of interest. Failure to distinguish between being a stakeholder defining needs, and the process of defining requirements leads to great confusion and difficulty in the practice of SE. anonymous Nov 20 at 2:28 pm
CommentStreams:7705f344a8314932199fd40fb17c4ed0 Product Systems Engineering Background Complicated systems need SE There is a comment that some products are not "complex" enough to need SE. This is misleading, and retains the wrong idea that "emergence" is only associated with complex situations, and complicated systems do not benefit from SE. The issue is around precedence in complication, and maybe the complexity of the organisation that produces the system - leading to the need to do SE to prevent "sub-optimisation". Many of the systems that have benefited from traditional good SE (rockets, satellites, planes, trains, buildings) are "merely" complicated, but certainly needed SE. anonymous Nov 20 at 2:21 pm
CommentStreams:A6efe37acef92e3ce0627762d189bda0 Logistics logistics not just for Operational support if you are producing a system (ie its hardware) do you not need logistics just as much to get the parts needed for production available (to standard) using logistics? anonymous Nov 19 at 11:31 am
CommentStreams:0dd7f8e12b54c6acbc58821ca8dcda72 System Validation This does not really make the clarity of difference between Verification and Validation I'm afraid the uninitiated reader would look at this and be unable to tell you clearly the significant difference between validation and verification. Try starting with the simplest premise - Verification shows the system meets the stated requirements, validation confirms that those requirements were correct and that what was asked for / delivered is actually valuable. anonymous Nov 19 at 11:05 am
CommentStreams:0d40e3541209e22f42503d7edf6e21e5 System Life Cycle Process Models: Vee Title is misleading - The V is much more a model for how to structure the data produced by the processes I am afraid I do not like to see the V model described as a process model. it perpetuates the myth that SE is a waterfall approach, and for many makes the V model seem wrong.

The V model is much more a way to understand how to structure and mature the information produced by Systems Engineering models. It is also unfortunate that amongst the figures you do not show any of Forsberg's views of multiple horizontal lines showing the different levels (you do have the nice figure showing the broadening) - and therefore missing the iteration between the levels, and the vital fact that each element in each level can (if say engineered by a different organisation) be "considered" as a system. I'd recommend the Assurance V from the 2013 paper - Scheithauer, D. and Forsberg, K., 2013, V-Model Views. INCOSE International Symposium, 23:pp502–516. What you have does not show the frequent and necessary iterations between each process in a level (e.g solution iterating with requirements) and continuously between the levels. The point I fail to see is the impoirtant activity that happens in the middle of the V (so you need to explain why the horizontal lines across the whole model are the key aspect

CommentStreams:836a7286b191b3f5ca6107361a348c9d System Requirements Elicitation There are quite a few other techniques besides interviews. Focus Groups, surveys, user stories, prototyping, QFD, Simulation and functional modeling for instance. Also business analysis is used to develop the data and requirements. Mission analysis is common in defense programs, business analysis in commercial programs. anonymous Aug 22 at 5:24 pm
