Title: Poorly Formed Requirements Assessment - Using the characteristics and rules defined in the INCOSE Guide to Writing Requirements (GtWR) to define well-formed design input requirements (Continued)

 

Abstract:  This is the first of three presentations where the rules contained in the GtWR are applied to a set of poorly formed requirements, assessing the defects (violations of the rules), and providing an improved version of each requirement that is well-formed per the rules in the GtWR. The set of system level design input requirements being defined is for a Lid Installation Robot (LIR) whose function (intended use) is to install lids on jars.  Given the number and types of requirements included in the overall set of LIR requirements, follow-on presentations will pick up where this session ends, continuing with the set of requirements.  Each session will address different types of requirements that should be included in a complete set of design input requirements.

 

While presentations have been made concerning an overview of the GtWR and a more in-depth presentation on the rules for writing well-formed need and requirement statements, there is a demand for live, interactive series of presentations, where the rules are applied to requirements for an actual case study and attendees have the opportunity to be actively involved.   Learning is enhanced when theory is applied to an actual real-world system to be developed.  The intent is for this to be an interactive activity where attendees are first asked to identify defects, discuss the presenter’s identified defects, and then discuss the presenter’s improved version of the defective requirements.

 

This will be a great learning experience for attendees – the devil is in the details and until you can apply the rules to a real case study it will be difficult to be proficient in defining well-formed requirements. To get the most from this series of presentations, while not mandatory, attendees are encouraged to first view the generic presentation on the rules defined in the GtWR.  This presentation can be assessed using this link: https://www.youtube.com/watch?v=QCmfxXTOcs4

IW2023: International Workshop Focus and Outcomes

The RWG won two awards during the IW2023:  Product of the Year (for the Needs and Requirements Manual and associated Guides), and Outreach.  Thank you INCOSE!

We are grateful for those that participated in our RWG pre-IW virtual sessions earlier this week, the guest speakers were excellent and they brought some great content to our members. If you would like to see any of this event, please see the recordings at our YouTube channel, and the slides are at the new RWG iNet site for IW2023 (replaces the old Connect site).  A big Thank You to the presenters, we appreciate your involvement and content!

The RWG meetings at IW2023 were held Sunday and Monday, 1 pm – 5:30 pm, at the Pier 4 conference room, and on Zoom. The topic was"2023 updates to the Guide to Writing Requirements". 

RWG co-chair Lou Wheatcraft went over the concepts from the Needs and Requirements Manual and the current Guide to Writing Requirements.  The rules and characteristics of well formed needs and requirements were discussed with the meeting attendees, prompting active discussion and questions which helped the WG as input into the next version of the Guide.  The TPP for the GtWR has been submitted, the inputs will be applied, and a full review of the content is planned in order for the revision to be released by IS2023.

Additionally, several topics for monthly presentations have been provided, allowing us to set up our working group meeting plans for 2023, starting in late February.

Thanks to those that joined the conversation!

Regular RWG Activities

  • Regular Web Meetings, Speakers or Exchange Cafés (~monthly)
  • Continued CAB Interactions and Support
  • Engagement with other Working Groups (IV&V, Security, others)
