Applications

The Enterprise Architecture Applications portfolio is responsible for understanding the form and condition of the organisation's applications.

In this context, an "application" can be defined as:

  • 'a software asset that contains an embedded business process or is configured to support a business process within which information assets are used or created' (Queensland Government ICT Planning Methodology 2007), or
  • 'a deployed and operational IT system that supports business functions and services; for example, payroll. Applications use data and are supported by multiple technology components but are distinct from the technology components that support the application.' (TOGAF)

The focus of the CSU Applications portfolio includes:

  • What applications we currently have
  • What applications are needed now and in the future
  • Application 'health'
  • How individual applications are architected
  • Together with the other Enterprise Architecture portfolios - how applications fit together within the broader environment

The Applications portfolio is managed by the Enterprise Architect (Applications).

Key Concepts

  • Governance – the ISIP Governance Committee provides governance over resourcing application activities at CSU. The Data Governance Committee also has a keen interest in the application portfolio.
  • Custodianship – Enterprise Architecture has custodianship of the application portfolio listing in conjunction with the Applications team within DIT. Additionally, custodianship of individual applications is shared between the Applications team and business owners across CSU. A document defining Technology Product Role Definitions is currently being developed and will be available on this site shortly.
  • Health – In the past, the age of internal applications and the version currency of purchased applications have been used as application health measures. A new health assessment framework has recently been developed and undertaken by the Enterprise Architect (Applications) to include:
  1. Measurement across business value
  2. Business impact
  3. Information condition
  4. Application technical condition

My application is not meeting my needs. What should I do?Depending on the situation, this may be a simple fix or require a more in-depth solution (e.g. initiating a project) to address. In the first instance you should contact Paul Bristow (Enterprise Architect, Applications). Depending on the circumstances, other CSU Enterprise Architects may need to be involved.
Do we have an application to do X?The Applications Portfolio Catalogue [.pdf] lists our applications with a short description of what they do. For further investigation, please consult Paul Bristow (Enterprise Architect, Applications).
What is the best way to build my new application?The Application Standards contain information on how CSU applications should be structured and constructed. Please contact Paul Bristow (Enterprise Architect, Applications) to discuss your application.
