A report issued by the Institute of Employment Studies advises people to enhance their employability by moving from traditional technical skills towards the attainment of a range of transferable skills. ****However****, it warns that employers often identify training needs through formal appraisals, which take too narrow a view of development.****Instead****, special schemes should be established to encourage people to examine their effectiveness and to consider a wider range of needs.
