Call for Consultants – Microsoft Excel User Interface Expert for Short-Term Consultancy | Closing Date: May 4, 2018

Johns Hopkins Center for Communication Programs (CCP) is seeking a User Interface Design (UI) consultant, with an expertise in customizing Excel UI and dashboards, to develop a user-friendly interface for an Excel-based tool. Specifically, this consultant will be hired for VectorWorks, a malaria prevention project is funded by PMI.  The primary aim of VectorWorks is to scale up vector control for malaria prevention through the distribution of insecticide-treated mosquito nets (ITNs). To that end, VectorWorks developed an Excel-based modeling tool called NetCalc, designed to model different insecticide-treated net distribution scenarios using country-specific data, providing estimations of the ability to meet optimal net coverage targets in a country, and therefore, optimal protection against the disease. VectorWorks would like national malaria program management teams and technical assistance providers to use this NetCalc tool for their net quantifications without needing to provide continuous in-person trainings, and we are therefore embarking on an effort to make this tool more user-friendly and intuitive. A visual dashboard should allow users to experiment with different scenarios through easily understandable graphs and charts, which are currently already part of the tool but could be more usable for new users.

The VectorWorks team collected information from users ranging from individuals who are very experienced with NetCALC to new users, on the challenges and benefits they derive from the tool.  Through this data collection process, VectorWorks identified several insights and design considerations that the consultant will be expected to bear in mind. NetCalc users and their reasons for using the tool vary widely. Although NetCalc is capable of performing many functions, it is important that each user can be guided through NetCalc based on the output they desire without confusion or ambiguity and that the output is also clear and comprehensible. This qualitative data will be available for the consultant to consider as they work to make the tool more user-friendly.

We expect the consultant to consider human-computer interaction and begin with empathizing with users and work toward a resolution. It is important to note that while we require strong skills in Excel, we do not expect the consultant to make any adjustments to the tool’s formulas or codes, but rather focus on the user interface. The challenge will be to make something user friendly, useful and visually interesting, so malaria prevention professionals want to use NetCalc to fit their individual and country-specific needs.


Consultant will have the following:

  • Minimum 2 years of UI design experience with training or experience in user experience and information architecture.
  • Strong skills in Excel and customizing Excel UIs and dashboards.
  • Bachelor’s degree or higher is required. Degree in Human Computer Interaction (HCI), Information Design, Visual Communications or related field is a plus.
  • Understanding of the relationship between people and products.
  • Excellent verbal and written communication skills
  • Strong organizational, problem-solving, and analytical skills

Our Audience

The primary audience for this new user interface includes government workers in malaria-endemic countries in sub-Saharan Africa who regularly estimate national insecticide-treated net distributions, as well as technical assistance providers from global health organizations and non-governmental organizations who work with country teams to support them in malaria prevention program management.
