Professional Portfolios: Showcasing your Technical Communications Skills 
A portfolio is a technical communicator's most important marketing tool. It showcases talents and abilities while giving prospective employers or clients an opportunity to learn about the candidate's skills and career direction. Often, communicators either do not have a portfolio or have not presented their works in the best possible manner. Professional portfolios are as indispensable as a resume. As the focus of technical communication expands, the need for multiple media to present a communicator's work is inevitable. Rather than a portfolio, multiple portfolios--in hard and electronic--formats are necessary to successfully portray your skills and career direction.
