Efficacy is different from efficiency. It is important for strategic communications practitioners to differentiate between both outcomes in our planning for programmes and campaigns. Doing something quickly or cheaply is a waste of resources when it is impact that one is looking for.

Many strategic communications practitioners face the same challenges when it comes to metrics and measuring the outcomes of their programmes. These challenges include demonstrating speed to market, measuring the value provided to their brand and organisation, how efficiently resources were deployed and the effectiveness of the programme in producing a desired behaviour.

We argue that efficacy (or effectiveness) is different and more desirable than efficiency. Let us define the terms properly to reduce any confusion.

When we measure efficacy of a programme or a campaign, we are looking at the value, impact or benefit produced that influences an action or behaviour we want the customer to take. This can be measured as an action, for example conversion or purchase; as well as behaviour, for example moving the decision to the next stage or referring the product to their community.

In contrast, when we talk about efficiency of a campaign, we refer to how well we can accomplish our goals and objectives with the least use or wastage of resources. These resources can refer to budget, time, and manpower. To be thorough, practitioners should also tally agency resources, third-party costs as well as time spent optimising and tweaking the plan during execution. These costs are often regarded as ‘investment’ or ‘sunk cost’ and can give stakeholders a wrong impression that the programme is not proceeding according to plan. Do be aware of the sunk cost fallacy in decision making though.

The importance of setting clear and realistic goals and outcomes for programmes and campaigns

Setting clear and realistic goals and outcomes is a critical step for any strategic communications programme or campaign. Regardless of whether the plan is built ground-up or reverse engineered, the key step is to set the outcomes and how to measure these outcomes in relation to business goals.

It bears saying that these measurements should be both qualitative and quantitative and map to the programme and campaign objectives.

Being realistic with the outcomes will make measuring the programme’s efficacy easier.

Measuring efficacy of programmes

When it comes to measurements, stakeholders tend to prefer quantitative metrics. It is easier to report, and a formula used to determine the increase (or decrease) over time (for example, year-on-year, month-on-month and similar). The ‘number’ layer should form the baseline of a report, since it is the most accessible means of accounting for the performance of a programme. With accessibility, stakeholders can be reassured efficiently about progress.

However, it should not be the only layer or means to prove efficacy. This would be discounting the qualitative and intangibles that situations often throw up.

As shared earlier, we have also considered proxies for actions and behaviours as a measurement. It is useful to demonstrate that these behaviours helped achieve the goals and outcomes more than through numbers alone.

These intangibles must be measured as well but given their qualitative nature, the descriptor and the demonstration of value must be easily understood. It bears spending time to map the measurement, proxy and descriptor to the specific goal or outcome it will support and explain how it does so. When the metric is pulled up, this explanation should follow along so the measurement is always viewed with context.

If discussed at the pre-campaign stage, it is also good to secure understanding and ownership by stakeholders.

For example, measuring engagement of customers through virtual events can be quantitatively measured by attendance, number of questions asked and sales conversions. From a qualitative perspective, the number of participants who do not drop out before the CTA is made, whether any post-event sales appointments are made and whether participants refer the event to their community are good proxies to consider.
