Is your ministry impact as significant as you think? Accurate field data is an essential ingredient for strategic planning and outcome evaluation. One significant challenge is overconfidence in the accuracy of the data -- a bias that can make the information seem more reliable than it really is. Understanding this common bias and taking steps to validate assumptions can produce a clearer picture of ministry impact while also identify overlooked opportunities. In this webinar (recorded May 21, 2020), Gilles Gravelle will examine this key issue and offer practical tips from his 30 years of global mission experience.
