It wants to create a single set of job descriptions and skill levels for all UK IT professionals in both user and supplier organisations.
The project will make it easier for IT departments to assess the skills of consultants and suppliers, and whether they have the right skills for the job, said BCS chief executive David Clarke.
"If someone is a project manager level-three in one supplier, he might be a senior project manager in another. In future, customers will know what they are getting," he said.
The BCS is working with suppliers to map the skills of their workforce to industry standard the Skills Framework for the Information Age (SFIA). Last year IBM became the first supplier to map its internal skills framework to the BCS SFIAmodel.
Other suppliers and user organisations are keen to follow IBM in adopting a standard model for assessing and measuring the skills of IT staff, said Clarke.
"All the companies we have been talking to feel there is a real benefit in having a single structure. They want to make sure they have competent, qualified people who are employed to do the right thing," he said.
IBM and the BCS mapped three internal IBM professions - IT architect, specialist and consultant - to the SFIA. Staff working in these areas now qualify automatically for BCS membership, allowing their skills to be recognised outside IBM.
"SFIA is an enabler to allow clients to have confidence," said IBM senior engineer Chris Winter, who initiated the programme.
