Professional Ethics

Why Professional Ethics?• Perhaps?

– Doing good– Being honest and trustworthy– Doing the right thing– Doing things right– Not screwing our customers/ the competition

…• What is your view of Ethics?

Ethical Focus• Ethics of Duty

– Duty owed to who?• Company• Customer/User• Society

• Ethics of Consequence– Who could be affected?

(Note these may be in conflict with each other)

IEEE / ACM Code• “Software Engineering Code of Ethics

and Professional Practice”• Software Engineers shall

– Act in the Public Good– In the best interests of clients and employer– Ensure products meet highest standards– Maintain integrity and professional

independence– Be fair and supportive of colleagues– ….

Examples for Discussion• Accept full responsibility for your own work• Not knowingly use software obtained illegally• Be honest about the limits of your experience and

competence• Ensure achievable goals for any project• Ensure adequate specification, realistic estimates,

adequate testing …….

IEI Code• Behave at all times with integrity• Maintain highest standards of

competence and conduct• Responsibility to yourself, society,

clients, employer, colleagues• Take account of social and societal

impacts

And Finally…….

Product v. Process

Process Axis (doing things the the right way - i.e. complying with best practice)

YES NO

The right thing done the right way

The right thing done the wrong way -

good product from poor process

The wrong thing done the right way -

useless product from good process

Disaster !!

SWEBOKDeveloped by UQAM (University of Quebec in Montreal) on behalf of the

Software Engineering Coordinating Committee (Joint committee of IEEE Computer Society and ACM) and submitted to ISO/IEC/JTC1/SC7 the standards sub-committee for information systems engineering, part of a joint technical committee of ISO and IEC

Characterisation of the bounds of the software engineering discipline:- Software requirements - Software configuration management- Software design - Software engineering management- Software construction - Software engineering process- Software testing - Software engineering tools & methods- Software maintenance - Software quality

see www.swebok.org

CPD definition

‘The systematic maintenance, improvement and broadening of knowledge and skill and

the development of personal qualities necessary for the execution of professional

and technical duties throughout the individuals working life’

The aim is to promote skill development and life-time learning

ICS approach to CPD• Under ongoing evolution

• Compatibility with IEI

• Compatibility with European initiatives, through CEPIS the European umbrella for computer societies– commencing with EUCIP

• Built on a skills framework

SFIA Skills Framework for the Information Age

• Developed in conjunction with 30 companies in the UK

• Employers: measure skills - available vs needed

• Individual: benchmark skills needed for particular job or career path

• Market: labour market intelligence;– skills requirements– skills in short supply– education and training targets

SFIA the model

Range of skills

L7 set strategy, inspire, mobilise

L6 initiate, influence

L5 ensure, advise

L4 enable

L3 apply

L2 assist

L1 follow

SFIA services• Career entry, career progression• Skills gap, skills development planning

• Education & training available - skills & skill levels addressed

• Accreditation of training• Certification of course participants

• Possible skills shortages• Profiling existing skills available

CPD operation• Individual plan for training & other development• maintenance of CPD log book • registration of CPD with ICS

• CPD plan and achievement used for career progression, for qualification recognition, and for ICS membership progression

• accreditation of CPD schemes• accreditation of training courses

CPD operation• Employer scheme: promote, support, accredit

– gives substance to the training commitment– fill skill gaps, improve competence– help achieve qualifications– support career development paths

• Individual scheme: promote, support, register– gives (more) control to the individual– provides logging of CPD achieved– can link to ICS membership progression

Communications• Importance• Forms and roles• Need for formalisation

Purpose - Mechanism - Outcome

Teamwork• Working effectively & efficiently together

• Team dynamics & team-building

• Everyone is different - personal and relationship traits• Role playing - multiple roles per person

• Person is a specialist - the specialist contribution• Need for - self discipline - communication

- progress tracking - decision making

Why Important

• One person can not do everything– do not have the time– do not have the skills

• Each has specialised contribution– skills– experience– ideas

Obstacles to working well together

• Poor forward planning

• Aims not clear

• Ideas not well developed

• Poor organisation

• Poor team work

Stages of Team DevelopmentStage 1: undeveloped- feelings not addressed- workplace is for work- no changes- poor listening

Stage 2: experimenting- experimentation- discuss risky issues- consider wider options- discuss feelings- more listening- more concern for others

Stage 3: consolidating- methodical working- agreed procedures- agreed ground rules

Stage 4: mature- high flexibility- appropriate leadership- energy and ability- principles- social- individual needs- improvement

Teamwork requires Team Building• Roles - define primary, secondary - skillset for each -

team allocates - ensures “skill recognition and application” - recognises “relationships between roles”

• Empowerment - team to decide aspects of process, techniques and tools, project stages and number of iterations - ensures “use of discretion” by team members, raises their self-esteem

• Communication - decide forms of communication for most critical aspects of project, for planning, assessment, review, action - in line with key features of project, special skills of team, culture of project

Team Roles

Belbin Test• Selects Roles on Teams• Used in DSDM (RAD) Method• Seven Questions• Allocate Ten Points between Questions• No Time Limit• Go on Instinct !!

Team roles• Every team needs different types of people

– leader, follower– thinker, idea generator– technical person, business person, people person

• Think of the best team that you were part of– it probably had many types of people– many types of skills– many types of synergies and conflicts and they worked well

together

Team Working

Different teams

• clearly defined role for everyone in the team

• concrete, measurable goal

• visible competition for the team to unite against

• has a coach

• many people not sure where they or others fit

• goal(s) never been spelt out - different people have different ideas of what they are

• competition inside the team as well as outside

• left to its own devices

Football team: Work team:

Does your team PERFORM?• P• E

• O• R

roductivity Is the team getting enough done?mpathy Do the team members feel

comfortable with one another?oles & goals Do they know what they are

supposed to do?lexibility Are they open to outside influences

and contribution?penness Do they say what they think?ecognition Do they praise one another and

publicise achievement?orale Do people want to be in this team?

Team Ground Rules• Team problems are everyone’s responsibility• Team time belongs to the team• Respect one another

– no put downs – support the other members of your team
