How a bioinformatics consulting session often started…
“I just spend $$$$$$$ to run a bunch of MS spec, and I have no clue what is in there. My BOSS is !#!@$%^&*@, and he is going to KILL ME!!!”
Client’s Start-Up
- Client realizes the presenting priority and need for a consultant
Cham, phdcomics
Engagement and Agreement
- Client and consultant meet to discuss presenting problem- Identify information needed to analyze presenting
problem- Organize and analyze presenting problem- Form an initial agreement about how to work together
Preliminary Discovery
- Analyze project priorities - Literature and method review- Information quality control- Identify limitation of project scope- Develop plans for evaluation and deliverables
Action Planning and Alignment
- Formalize project plans (Statement of Work)- Allocate physical and human resources- Devise a budget justification- Communicate with client to agree upon the budget
Implementation Evaluation
Project Termination (End Project)- Final project presentation- Agree on data deliverables- Agreement on acknowledgement/authorship for
publication- Billing
“Why isn’t it statistically significant ?”
Summary
Collaborative research consulting is a fee for service operation
Stepwise short and focused project objectives
Fast turn-around time (~2-3 weeks) Reiteration the same process for long
term collaboration
