Goals of EngineeringGoals of DesignMotivation for Human Factors in DesignAccomodation of Human DiversityGoals of our ProfessionPractioner’s SummaryResearcher’s Agenda



Goals of Engineering

Successful designers go beyond the level of notion of thinking

(E.g) ISRO scientists design

ONGC Engineering controlling blow-outsEtc.



For Human Engineering Design Achieve needed Performance by operators, control of maintenance personnel. Minimize skill & personnel requirements & training time. Achieve needed reliability of personnel equipment combinations Foster design standardisation within and among systems.



Goals Proper – functionality Reliability Availability Security Standardization / Integration Consistency Portability Schedules Budgets



Goals of User 5 Measurable factors are :

Time to learn Speed of performance Rate of errors by users Retention over time Subjective Satisfaction

Motivation for Human Factors in Design

Life critical systems Industrial & Commercial uses Office, Home & entertainment appln/.. Exploratory, Creative & Co-operative Systems

Statistical Hypothesis formation Graphical presentation of scientific data Business Decision Making



Creative

Writer’s tool kits Architecture or Automobile design Music Composition System Artist work station

Co-operative Systems

Electronic text 2 or more Voice Mail jointly work Video Mail



Physical Work place

Ensuring high job satisfaction High performance Low error rates

Cognitive & Perceptual abilities

Short-term memory Long-term memory Problem solving Decision making Attention Search & Scanning Time perception Knowledge of Results



Factors affecting …

Monotony & boredom Anxiety & fear Isolation Aging

Personality Differences

Some dislike systems Others are attracted



Managing Design Processes

Organizational design to support usability Three (3) pillars of design Development methodologies Ethnographic observation Participatory design Scenario development Social impact statement for early design

review Legal issues



Organizational design to support usability

Carroll & Rosson (1985) Characterization :

1. Design is a process2. Non-hierarchical3. Radially transformational 4. Discovery of new goals

Three Pillars of Design1. Guidelines documents & processes

2. User-interface tools3. Expert reviews & usability testing



Ethnographic observation(Early stages of most methodologies )

Preparation Field study Analysis Reporting

Preparation

Understand organisation policies & work culture Familiarize with systems & its history Set initial goals / prepare questions Gain access & questions permission to observe



Field study Establish rapport with Manages / users Observe the users in work place collect data Follow any leads that emerge from visits Record your visits

Analysis Compile collected data Quantify data & compile statistics Reduce / interpret data Refine goals / process used

Reporting Consider multiple audiences /goals Prepare report / preset findings



Participatory design Usually positive Careful selection of users is successful Organizational policies, particularly design preferences of individuals

Scenario Development Flow chart Day in the life creates scenario in many designs



Social impact statement for early design Describe new systems & benefits Address concerns and political barriers Outline the development process Legal issues

Describe new systems & benefits

Address concerns & Political barriers Anticipate changes of job fuctions Addl.security / privacy issues Discuss Accountability / Responsibility



Address …. Weigh individual rights Centralization / De-centralization Preserve democratic principles Promote simplicity

Outline the Development process Pre-set an estimated project schedule Propose process for decision-making Discuss expectation of stock holders Recognize needs of more staff, Training Plan for migration to new systems Plan for measuring the success of

new-systems



Legal issues What material is eligible for copy-right Are copy-rights or patents more appropriate for user-interface ? Should user-interfaces be copy-righted ?



Expert Reviews Methods

Heuristic evaluation Guidelines reviews Consistency inspection Cognitive walk through Formal usability inspection



Surveys Goals tied to the components of design Task domain objects & action Interface domain metaphors and action handles Inputs & design of displays

Other Goals Back ground Experience with computers Job responsibility Personality style Reason for not using interface Familiarity with design features Feelings after use of interface



Interface Building Tools(properties)

Separate interface design from intervals Enable multiple user-interface strategies. Enable multiple platform support. Establish role of user -interface Architect Enforce Standards

Methodology & Notation Develop design procedures Find ways to talk about design Create project Management



ONGC Practice
