Enterprise Architecture Quarter

Product Design Quarter (hereinafter, the Quarter) is the third of four lectures of Project Quadrivium (hereinafter, the Quadrivium):

• The Quarter is designed to introduce its learners to enterprise design, or, in other words, to concepts related to creating architecture for achieving enterprise goals; and
• The Quadrivium examines concepts of administering various types of enterprises known as enterprise administration as a whole.

The Quadrivium is the first of seven modules of Septem Artes Administrativi, which is a course designed to introduce its learners to general concepts in business administration, management, and organizational behavior.

Lecture outline

The predecessor lecture is Business Analysis Quarter.

   • Product scope. The features and functions that characterize a product, service or result.

• Agile
• System. A set of interrelated and interdependent parts arranged in a manner that produces a unified whole.
• Open system. A system that interacts with its environment.
• Closed system. A system that is not influenced by and does not interact with its environment.

1. Systems engineering.
   • Datapoint-device architecture.
   • Configuration management.
2. Informational architecture.
   • Graphic design.
   • Usability.
   • UX design.

• Action design. A change process based on systematic collection of data and then selection of a change action based on what the analyzed data indicate.
• Commitment concept. Plans should extend for enough to meet those commitments made when the plans were developed.
• Load chart. A modified Gantt chart that schedules capacity by entire departments or specific resources.

Practices

• 3-Click Rule. A theory of website navigation prevalent in the early 2000s suggesting that a user of a website should be able to find any information with no more than three mouse clicks or they would leave out of frustration. It’s now widely accepted as nonsense; usability studies disprove the theory’s link to user satisfaction or success rates and instead link these to ‘information scent’.
• 5 Second Test. As the name suggests, the 5-Second Test involves showing users a single content page for a quick 5 seconds. The aim is to gather a participant’s initial impressions and assess the screen’s clarity and conciseness using simple questions like "What is the most important information on the page?" or "How would you go about achieving your goal on this screen?". The setup is similar to a standard usability test, and may sometimes be combined with one.
• Adaptive web design. Like Responsive web design it is an approach to web design aimed at crafting sites to provide an optimal viewing and interaction experience on different screen and devices. The difference is that adaptive design is less fluid then RWD, and ‘serves’ few fixed width versions of the design depending on viewport size. It can utilise server side techniques to ‘detect’ viewport size prior to rendering html. The advantage for designer is that it gives more control over images and typography, and hence is easier approach to ‘retrofit’ fixed width websitest to work on mobile devices.
• Affinity diagramming. A business tool used to organise a large number of ideas, sorting them into groups based on their natural relationships, for review and analysis.
• Agile software development methodology. A methodology fundamentally incorporating iteration and continuous feedback to refine and deliver a software system. It involves continuous planning, testing, integration, and other forms of continuous evolution of both the project and the software.
• Analysis stage. The stage of the UX process where insights are drawn from data collecting during the earlier Research stage. Capturing, organising and making inferences from the “what” can help UX designers begin to understand the “why”.
• Analytics. A broad term that encompasses a variety of tools, techniques and processes used for extracting useful information or meaningful patterns from data.
• Axure. A wireframing and interactive prototyping tool, available for both Windows and Mac.
• Balsamiq Mockups. A wireframing and interactive prototyping tool, available for both Windows and Mac.
• Beta launch. The limited launch of a software product with the goal of finding bugs before final launch.
• Branding. The process of creating and marketing a consistent idea or image of a product, so that it is recognisable by the public.
• Card sorting. A technique using either actual cards or software, whereby users generate an information hierarchy that can then form the basis of an information architecture or navigation menu.
• Content Management System (CMS). Software that allows publishing, editing and maintaining content from a central interface. See also: Content management
• Collaborative design. Inviting input from users, stakeholders and other project members.
• Competitor analysis. Performing an audit or conducting user testing of competing websites and apps; writing a report that summarises the competitive landscape.

• Heuristic review. Evaluating a website or app and documenting usability flaws and other areas for improvement.
• Human Computer Interaction (HCI). HCI involves the study, planning, and design of the interaction between people (users) and computers.
• High-fidelity prototype. A prototype which is quite close to the final product, with lots of detail and a good indication of the final proposed aesthetics and functionality.
• Human factor. Also called ergonomics. The scientific discipline of studying interactions between humans and external systems, including human-computer interaction. When applied to design, the study of human factors seeks to optimise both human well-being and system performance.
• Industrial design. The application art and science to a product, in order to improve its aesthetics, ergonomics, functionality, and usability.
• Information architecture (IA). The art and science of organising and labeling websites, intranets, online communities and software to support usability.
• Information scent. An important concept in information foraging theory referring to the extent to which users can predict what they will find if they persue a certain path through a website. As animals rely on scents to indicate the chances of finding food, so do humans rely on various cues in the information environment to acheieve their goals.
• Interaction design (IxD). Sometimes referred to as IxD, interaction design strives to create meaningful relationships between people and the products and services that they use.

• Iterate. The act of repeating a process with the aim of approaching a desired goal, target or result. Each repetition of the process is also called an iteration.
• Iterative design. A methodology based on a cyclic process of prototyping, testing, analysing, and refining a product or process. Based on the results of testing the most recent iteration of a design, changes are made. This process is intended to ultimately improve the quality and functionality of a design.

• Paper prototype. A rough, often hand-sketched, drawing of a user interface, used in a usability test to gather feedback. Participants point to locations on the page that they would click, and screens are manually presented to the user based on the interactions they indicate.
• Personas. A fictitious identity that reflects one of the user groups for who you are designing.
• Production stage. The stage at which the high-fidelity design is fleshed out, content and digital assets are created, and a high-fidelity version of the product is validated with stakeholders and end-users through user testing sessions. The role of the UX Designer shifts from creating and validating ideas to collaborating with developers to guide and champion the vision.
• Project kick-off. The formally recognised start of a project.
• Progressive disclosure. An interactive design technique that helps maintain the focus of a user’s attention by reducing clutter, confusion, and cognitive workload.
