The trial seeks to identify a cost-effective, yet productivity-enhancing programme of peer-group learning for family business SMEs which can be replicated and run at scale.
The experiment addresses a key problem faced by the long-tail of low-productivity businesses in England by seeking to reduce barriers to the adoption of digital technologies that have been demonstrated to increase productivity.
By selecting family businesses with low rates of digital technology adoption and working with them in facilitated peer-groups the trial seeks to provide:

- the demonstration of measurable improvements in intent to adopt productivity enhancing digital technologies

- evidence of some adoption of the technologies before the end of the trial

- in the longer term, measurable increases in productivity, shown using data-matching methods

Experimental Design
Experimental Design
The Evolve Digital trial is profiled in the Figure below. The trial has two arms with trial subjects being UK- based family firms with less than 50 employees. In most cases firms will be in the 5-10 employee range. Baseline data will be collected after firms are accep- ted for inclusion in the trial and before randomisation. In addition to the treatment and control groups a comparison group from the general population of firms will also be included. These firms will be re- cruited to have characteristics broadly similar to the combined treatment and control groups. They will receive no treatment. A follow-up telephone survey of the treatment, control and comparison groups will be undertaken six months after the completion of the treatment.

Experiment Characteristics
Sample size: planned number of clusters
7 cohorts with 40 SMEs in each, totalling 140 treated SMEs and 140 in a control
Sample size: planned number of observations
Sample size (or number of clusters) by treatment arms
140 treated SMEs (Treatment intervention + control intervention + pre- and post-intervention questionnaires)
140 control group of SMEs (Control intervention and pre- and post-intervention questionnaires only)
140 comparison group of SMEs (Pre- and post-intervention questionnaires only)
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Intention to adopt (a four-item scale): For n=140, assuming control group mean=2, treatment group mean=3 and SD=2, then at 5%, power = 0.84. Attitude toward using (a three item scale): For n=140, assuming control group mean=1, treatment group mean=2 and SD=2, then at 5%, power = 0.84.
