Software Architects

The IASA provides information and education to practicing IT and Enterprise Architects. However, judging by their website, it seems to be aimed more at Enterprise Architects(?)

Australian Institute of Architects

SA Chapter address – 100 Pirie Street. No sub-categories as is the case with Engineers Australia Architectural design practices and principles cannot be applied in a field other than building/landscaping?

Bill Malkin

Design Institute of Australia

The DIA defines a designer as – a business professional that develops solutions to commercial needs that require the balancing of technical, commercial, human and aesthetic requirements.

Building Architects design in the physical world.

Software Architects design in the virtual world.

Bill MalkinSoftware Engineers and Architects –

Who needs ‘em?!

Bill Malkin

Question 1

Does a large building construction project really need a

Building (Civil) Engineer?

Bill Malkin

Answer No

But, with a Building (Civil) Engineer, the construction of the building is “more likely” to be successful in terms of:

Cost

Time

Reliability

Maintainability

Bill Malkin

Question 2

Does a large software construction project really need aSoftware Engineer?

Bill Malkin

Answer No

But, with a Software Engineer, the construction of the application is “more likely” to be successful in terms of:

Cost

Time

Reliability

Maintainability

Bill Malkin

Question 3

Does a large building construction project really need aBuilding Architect?

Bill Malkin

No But, with a Building Architect, the outcome of the construction project is “more likely” to be successful in meeting the client's expectations in terms of the building's: Look and feel on both the macro and micro scale. Ability to perform the function for which it was built.

General Understanding

1. Software Engineers are people who develop software within the Defence industry.

2. Software Engineers are people who develop software that implement complex algorithms.

3. Other.

wikipedia

Software engineering is a profession and field of study dedicated to designing, implementing, and modifying software so that it is of higher quality, more affordable, maintainable, and faster to build.

Bill MalkinIEEE Computer Society’s Software

Engineering Body of Knowledge

Software Engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering to software.

Bill Malkin

General Understanding

1. Software Architects have excellent business analysis skills and general technical skills. (Solutions Architect)

2. Software Architects have excellent technical skills and general business analysis skills. (Technical Architect)

3. Other.

Wikipedia*

The software architecture of a program or computing system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships between them.

Documenting software architecture facilitates communication between stakeholders, documents early decisions about high-level design, and allows reuse of design components and patterns between projects.

*Bass, Clements, Kazmann 2003

Bill MalkinDifferences between

Building Construction andSoftware Construction

Buildings:

Visible to all.

Can collapse and kill people.

Require tradespeople and labourers.

Require materials.

Easier to see progress.

Static, not dynamic.

Cannot be backed-up or duplicated.

Bill Malkin

Buildings:

Must conform to relevant statute laws, local council by-laws, safety regulations, etc.

Key personnel must be appropriately certified.

Position titles mean something, eg Site Engineer, Clerk of Works, Architect, Site Foreman...

Differences betweenBuilding Construction and

Software Construction

Software engineering* is a profession and field of study dedicated to designing, implementing, and modifying software so that it is of higher quality, more affordable, maintainable, and faster to build.

Civil engineering* is a professional engineering discipline that deals with the design, construction and maintenance of the physical and naturally built environment.

?They both have architects and engineers working in partnership.

Does this only happen in building construction and software construction?

Bill MalkinDifference between

Engineers and Architects Architect

Responsible for Form and Function, ie the Look and Feel, the Functional Requirements and the High Level Design.

Very close relationship with client. Requires excellent communicationskills.

Requires only basic technical skills. More art than science?

Bill MalkinDifference between

Engineers and Architects Engineer:

Responsible for Reliability and Maintainability, therefore the detailed design and the construction.

Very close relationship with construction staff.

Requires excellent technical skills. More science than art.

Bill MalkinConclusions

The Roles and Responsibilities ofSoftware Engineers andSoftware Architects

a) Software Architects focus on the client, and are responsible for the form and function of the application.

b) Software Engineers focus on the technology, and are responsible for the reliability and maintainability of the application.

(a) What, and (b) How
