Four Strategies • Identify Missing ‘Key’ Technologies • Evaluate Available Skills • Creatively Leverage Your Legacy • Prioritize Projects For Success
Strategy 1:Identify Missing ‘Key’ Technologies • If we only had… • Authentication?“Are you who you say you are?” • Authorization?“Are you allowed for this function?” • RPC Access to Legacy Environment? • Inventory in-house software • Consortium/vendor solution • Cash-free may not be possible… but be strategic
Strategy 2:Evaluate Available Skills • Identify Required Implementation Skill Sets • Data administration • DBA • Application analyst/specialist • O/S, network infrastructure specialist • Select Key Participants • Visionary, capable, team-oriented • Expert user(s)
Strategy 3:Creatively Leverage Your Legacy • Controlled e-volution • Use maintainable/sustainable technologies • Language environments, O/S’s, databases • Adhere to production policies and standards • Practical Examples • One-way data extracts (accessed via .cgi, .asp, etc.) • Relational to flat files FTP’ed to Web server -- Majors List • VSAM to relational database -- Transfer Courses
Strategy 3:Creatively Leverage Your Legacy • Practical Examples (cont.) • Leverage in-house technologies • E-mail Services • Request collection via Web • Output delivery via e-mail (batch processing) • Unused technologies -- Cougar TraCS • Distribute electronic data • Re-think our age-old report distribution model • Supply data for desktop decision support tools
Strategy 4:Prioritize Projects For Success • Applying a Bit of Objectivity... • Time estimate - S(1-3m), M(3-9m), L • Impact - S(? admin.), M(advising community), L(student population) • Cost (hardware, software licenses) • Quick Wins — SL or ML
Conclusions Small incremental steps can produce large sustainable returns. There are ways to move our applications forward in support of e-services — be creative.
