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!

• UNDERSTAND WHAT IS NFR
• HOW DIFFERENT NFRS FROM FRS
• WHY NFRS ARE IMPORTANT
• HOW NFR CAN BE IDENTIFIED OUT OF SYSTEM REQUIREMENTS
• MEASUREMENT OF NFRS
• ARRANGING NFRS
• ADDRESSING RIGHT SET OF QUESTIONS
• VERIFICATION OF NFR
8. Few Definitions...
“In software system engineering, a software requirement that describes not what the software will do, but how
the software will do it, for example, software performance requirements, software external interface
requirements, software design constraints, and software quality attributes. Nonfunctional requirements are
difficult to test; therefore, they are usually evaluated subjectively.”
Richard H. Thayer. IEEE
“Non Functional Requirements are constraints on the services or functions offered by the system. They include
timing constraints, constraints on the development process and standards. Non-functional requirements often
apply to the system as a whole. They do not usually just apply to individual system features or services.”
Ian Sommerville, Software Engineering, 7th edition
“A property, or quality, that the product must have, such as an appearance, or a speed, security or accuracy
property”
James Robertson, Mastering the Requirements Process: Getting Requirements Right
“Users have implicit expectations about how well the software will work. These characteristics include how easy
the software is to use, how quickly it executes, how reliable it is, and how well it behaves when unexpected
conditions arise. The non functional requirements define these aspects about the system.”
Andrew Stellman, Applied Software Project Management
9. Basic Differences in Functional and
Nonfunctional Requirements
Functional Requirements Non Functional Requirements
• Product features • Product property
• Describe the actions with which the
user work is concerned
• Describe the experience of the user
while doing the work
• A functions that can be captured in use
cases
• Non-functional requirements are
global constraints on a software
system that results in development
costs, operational costs
• A behaviors that can be analyzed by
drawing sequence diagrams, state
charts, etc
• Often known as software qualities
• Can be traced to individual set of a
program
• Usually cannot be implemented in a
single module of a program
10. Importance of Non Functional
Requirements
May be all functional requirements are working fine.
If Non Functional requirements are not handled well, the whole
system may fail and that may lead to..
• Loss of Business
• Loss of User Interest
• Loss of Credibility
11. Challenges for Non Functional
Requirements
• Implicit requirements
• No formal agreement
• Lack of awareness
• Incomplete Elicitation
• Different Terminologies across the industry
• Most of the contradictory
• Difficult to enforce during development
• Difficult to setup acceptance criteria
12. Type of NFRs
Important To Users
• Performance
• Security
• Usability
• Compatibility
• Accessibility
• Reliability
• Flexibility
• Interoperability
Important To Developers
• Maintainability
• Portability
• Reusability
• Testability
13. Requirement Elicitation
Identification of Non Functional Requirement starts with Requirement Elicitation.
Requirements Elicitation is the practice of collecting the requirements of a system from users,
customers and other stakeholders.
Requirement Elicitation Methods:
• Interviews
• Questionnaires
• User observation
• Workshops
• Brainstorming
• Use Cases
• Prototyping
Requirements elicitation is a part of the requirements engineering process, usually followed by analysis
and specification of the requirements.
During the requirement analysis the Non Functional Requirement can be fetched out and documented
14. Identification of Non Functional
Requirements
Non Functional Requirement can be identified by breaking the requirement in Tasks and Sub Tasks
Funct 1
Req 1
Req 2
Task 1
Tasks 2
NFR 1

• Identify NFR for each Task
• Establish the Goal
• Continue until you cannot decompose
further
Here we are taking the example of Security
Security
SSL
Implementation
Password Policy
Role Based
Authorization
PCI Compliances
Integrity of
Accounts
Data
Confidentiality
SSL
Implementation
Decomposition of Each NFR to meet the Goal
17. Measurement of NFRs
Measurement of NFRs are in very subjective in nature. There is no absolute scale of
all type of NFRs.
Sometime it is hard to measure quality of software in isolation until it is not into
correct environment. Software may behave differently in different environments.
Here is the solution…
We can identify good quality predictor by analyzing NFR during Design Analysis based
on:
• What is he purpose of NFR?
• What quality factor will impact the stakeholders?
• How these factors will be met?
18. Measurement of NFRs
Based on the Design Analysis, we can identify the Measurable Units for each NFR separately.
Identify
Quality
Factors
Define
Measurable
Criteria

Acceptance Criteria
• The system should
meet load of
1000 concurrent
users.
• The system should
meet load of 500
concurrent users.
20. Arranging NFRs
Arrangement of NFR can be done in a way, so that each NFR is traceable against each
Functionality. We are again taking example of Security
