"OMG: Modeling the Business. The Real Revolution". Richard Soley presentation at the BPM Forum 2013 in Milan introducing a day of Business Process Modeling with some thoughts about this change and the impact on both technology and business. In the ITC world, most of the focus on modeling has been on technical artifacts: software, configuration, test development, and so forth. In business analysis, most of the focus of modeling has been based on ambiguous, natural languages. These worlds are colliding now, with semantically-rich, precise descriptions of business models useful as the basis for detailed, exact business analysis, communications and metrics.

Project Controls Expo 18th Nov 2014 - Introduction and key note presentation ...Project Controls Expo
I believe that project delivery challenges are driving organisations towards greater integration and changing the way we should approach Project Controls within project delivery organisations.
This presentation captures my thoughts on a way forward for Project Controls within a Project Delivery organisation discussing:
Scope definition and Work Breakdown techniques driving more effective data integration (Single sources of key data from numerous functions)
Improvements in systems and system integration
Use of Data Warehouses and Management Information systems
Utilisation of BIM incorporating 4th (Time) and 5th (Cost) dimensions
Taking a simpler higher level approach to creation of a control model
Use of an Earned Value Management system and EV Maturity Compass
The need for a wider range of skills to deliver good control
An integrated industry approach to career definition, development, training and qualifications for Project Controls within the Project Management umbrella
My experience tells me that there is no single ‘magic ingredient’ to delivering successful projects; but greater integration of management and team activities, intelligent application of recognised best practices and fit-for-purpose processes, tools and systems would benefit UK construction as a whole in the future.

Pedro J. Molina: Essential 2.0 & Meow: Model Editors on the Web
Essential is a Language Workbench and tooling for implementing Model Driven tools on .NET initiated in 2008.
During this time the tool has been adapted to create metamodels, models, templates and model transformation in a complete integrated development environment (IDE). Essential has been used with success to prototype, create and evolve high-quality commercial code-generators.
In the last years, works to migrate Essential to the Web (version 2.0) has been performed to allow using its potential for cloud-based application and in the browser. Quid is one of the first tools created using Essential for Web. Moreover, Essential 2.0 is totally web-based and parsers and model editors has been recreated from scratch into TypeScript to fully embrace the Web platform and provide easy tooling for creating modeling environments on the Web. In this sense, Meow is a companion library for Essential to allow dynamically edit models on the web enforcing an arbitrary Essential Metamodel. Bindings for importing and exporting EMF ECore Models are provided to make it easy to reuse models.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
