There are various kinds of skills and knowledge bases, professional skills, attitudes, ethics, and the application ability of the engineering skill are primarily explained through the engineer's seeking to practice unsupervised and independently. Those skills could initially express professional usage of the Stage 2 Competency Standard. The main purpose of this competency standard is elaborating properly the Chartered membership of the Engineer Australia besides registration among the National Engineering Register (NER). The registration is initially granted according to the outcomes of Engineers Australia Stage 2 Competencies. The public worldwide besides the general government and businesses majorly seek that professional assistance.  A long career obligation for further ensuring greater competence and maintaining the standards within the chosen area which is generally facilitated through obtaining a CPEng is crucial. However, there are some essential and crucial expectations from professional engineers. Besides it is necessary for a particular experienced professional for living by those expectations concerning the manner of the self-conduction, and application of competence. Aside from this, the essentials and expectations from professional engineers are properly described below

• Showcasing the needs of society as regards whole, stakeholder requirements, and adequate understanding of the client requirement.
• Seeking the optimization of various kinds of outcomes that associates with the economy, environment, and society all over the program lifetime and engineering product.
• Effective inter-discipline and interpersonal interaction and effective public interaction.
• Facilitating total engineering contribution and integration among the process, program, and project.
• Holding prime responsibility for the government, business, and social possibility interpretation that mainly concerns technology.

However, along with the above-mentioned factor, there are still a few factors that professional and experienced engineers are expected to do such as

• Appropriately making the policy decision through the consequences and possibilities to the greatest extent.
• Properly understanding the limitations, risks, related costs, and desirable outcomes.
• Development of a suitable solution for the composite set of the sensor by applying adequate knowledge through some diverse sources.
• Taking care of the adequate consideration of both non-technical and technical integration.
• Managing risk for the further imparting sustainability
• Aligning fundamental principles and theories with all kinds of aspects and factors of the process, program, and project.
• Understanding the relation among experience, established practice, and new developments besides relation with another kind of interactive discipline.

The available communication between the technology and people are possibly considered through the experienced professional engineers alongside physical result, which are initially facilitated through the engineering outcome. The development procedure of all over engineering science besides technologies among all engineering disciplines by adequate research could be seen as massive responsibility for the experienced engineers. The maintenance and development of the providing knowledge and regulatory codes towards new engineers besides engendering the continuous procedure of improvement within the field is a further massive task and activity associated with them

The Engineers Australia stage 2 competency standards follow some of the factors and aspects which are properly given below.

• Technical proficiency
• Obligation towards community
• Personal commitment
• Workplace values
