The keys to Improving Sales Forecast Accuracy

Systematically_Improving_Sales_Forecast_Accuracy_Thumbnail.pngAs we’re all very well aware, complex sales are complicated. There are subject to a wide range of factors that are outside of our direct control. It’s no wonder that forecasting if and when any individual deal is likely to come in is such a challenge.

Research by CSO Insights has shown that less than half of forecasted deals actually close on the date and at the value originally expected. Many close dates slip (often repeatedly) and many of these forecasted deals never close at all.

If you’re in a short cycle transactional sales environment, high deal volumes and the law of averages can blur the impact of this uncertainty. But if you’re involved in a high-value long sales cycle situation the impact on revenue can be much more serious…

We can’t control the truly uncontrollable, and we can’t know the truly unknowable, or anticipate the truly unpredictable. But many of the remaining forecasting errors are down to things that we could and should have known or done.

We can have a big impact on forecast accuracy – and generate a much more reliable revenue stream – if we all simply make sure that we know the knowable, do the doable, and control the controllable, and make sure that the rest of our sales organisation does the same.

That’s the underlying theme of a webinar I recently recorded with the UK’s Association of Professional Sales. You can watch it on-demand here or by clicking on the image below.

Here are my key recommendations:


It’s impossible to have confidence in the numbers in our forecast without a clearly defined, highly effective and widely adopted sales process. As W Edwards Deming (father of the quality revolution) so aptly put it, “If we can’t describe what we are doing as a process, we don’t know what we’re doing”.

Effective sales processes must:

  • Include a series of clearly-defined stages that reflect the buying decision journey
  • Require progress to be based on the prospect achieving verifiable milestones
  • Offer clear guidance as to what sales people need to know and do at each stage

Establishing unambiguous forecasting guidelines is every bit as important as having a clearly defined sales process. We need to implement clearly defined categories, such as COMMIT, PROBABLE and UPSIDE and be clear about how each category must be implemented in practice.

We need to apply a similar rigour to “close dates”. One of the most common causes of forecast inaccuracy is to apply a close date that the sales person aspires to but the prospect has no obvious reason to comply with. Repeated close date slippage is a classic indicator.

Finally, we need to make sales people accountable for the accuracy of their forecasts – and that means measuring their actual performance against forecast. This is not an opportunity for punishment – it’s an opportunity for coaching.

It’s all very well having a defined sales process – but we need to take steps to ensure that it is adopted. That requires that our sales people believe that it is in their interest to follow it, and that they further believe that they will be more successful if they do.

Incorporating the winning habits of your top sales performers into the process is a critical element of getting buy-in – and it’s hard to imagine how you can define a truly effective sales process without their inputs.

Implementing a handful of critical checklist items per stage, highlighting relevant materials and applying simple visual REDAMBERGREEN status flags can have a transformative impact on process adoption. You can learn more in the webinar.


We can no longer afford to rely on spreadsheets and tabular reports to help us see what’s really been going on in our pipelines or to make any sort of informed judgement about the short or long term future. Of course, selling depends on creativity but it also depends increasingly on data.

That may be why investing in sales analytics is the top technology priority for many sales leaders in 2016. Unlike traditional BI solutions, specialist sales analytics applications from organisations like InsightSquared answer key sales management questions without the need for IT involvement.

Perhaps most powerful of all, the dashboards and reports of these specialised solutions are being continuously enhanced to reflect the accumulated learning from hundreds and thousands of sales organisation. They can not only answer the questions you have already thought of, but also come up with insights you may never have dreamed of.

Successful selling is not just a combination of art and science – creativity and data – it is also increasingly about engineering: recognising patterns of success and failure and systematically applying proven process to amplify the former and eliminate the latter.
