Unit Descriptor
This unit describes the performance outcomes, skills and knowledge required to design the structure of software or systems components and how they interact. The unit focuses on layered architectural style.
Application of the Unit
This unit is relevant to those who work as software architects, developers, designers, software engineers or programmers responsible for designing and building solution architects.
This unit addresses the knowledge and processes necessary to produce the high-level design (blueprint) of a system.
Licensing/Regulatory Information
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.
Pre-Requisites
Not applicable.
Employability Skills Information

Performance Criteria |
|
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
|
1. Gather and confirm architecture requirements |
1.1 Gather information regarding architectural requirements 1.2 Establish and document architectural requirements |

2. Design layered architecture |
2.1 Separate the areas of concern into logical layers 2.2 Determine the cross-cutting concerns 2.3 Define the system into components 2.4 Identify the responsibilities of each component 2.5 Identify interconnections between components |
|
3. Plan a strategy to re-use components |
3.1 Determine an appropriate strategy for communicating with external systems 3.2 Interact with existing legacy components |

|
Guidance information for assessment |
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
