The Effectiveness Partnership What We Work On


What our clients say about us

“The Effectiveness Partnership is great. They have helped us put a discipline and a framework in place when it comes to evaluation right across Grey EMEA.
The interesting thing is that this focus on evaluating the results at the end of our work, also helps our planners take a more commercial approach right at the start of the communications process too.

Not only that, but we’ve found them equally helpful when it comes to clients with limited data as well as those who are drowning in it and need to organise their thinking. So, they worked with us on the British Heart Foundation, where we had very little data to work with and some really creative approaches to evaluation and benchmarking were required. They also worked with us on GSK, where we’ve been exploring brands with decades of data across multiple countries.” 

“Their training courses add value and are fun, and their comments on IPA Effectiveness Awards entires have been hugely insightful. They bring a real-world business perspective to analysis and they have a gift for explaining complex issues in simple language.”
“As a business we have only recently committed to making the effects of marketing more measurable. The Effectiveness Partnership have been an excellent partner in this process as they have been able to deliver good quality analysis at a competitive price. After the initial debrief I have been impressed by their ability to turn around subsequent work with tight deadlines as well as by their commitment to supporting our developing understanding of economics.”
“They bring a mountain of experience, clear sightedness, rigour, and tough questions. A voice of reason and inspiration, they’re nice, smart, relentless people who most definitely add enormous value.”
“I have applied all the techniques I was given on an important presentation the very next day after The Effectiveness Partnership’s Strategic Storytelling course.

I felt confident enough to re-write my presentation with the new structure and the feedback I got from clients was very positive.

This course was an excellent way of acquiring new methodologies and tools I was craving for on my profession. The Effectiveness Partnership’s Story Telling Course is definitely a good investment!”

“Effectiveness is not normally considered the most exciting part of the advertising process, but The Effectiveness Partnership make it clear, they make it simple, and even pull off the remarkable feat of making it fun.”
“The team at the Effectiveness Partnership, helped us to develop a far better understanding of the effectiveness and relative merits of using a variety of marketing and sales promotion tools, which resulted in a more targeted (and ultimately more effective) use of our relatively limited budget. Ultimately we used their input and recommendations to help us develop an annual brand plan which delivered maximum returns on investment for the business.

I found working with the team at the Effectiveness Partnership to be both stimulating and challenging. Stimulating in terms of the breadth and depth of thinking that they brought to the project and challenging in terms of the way that their up front interrogation of the available data (and ourselves) made us really think about and re-frame the questions we were trying to answer. This resulted in the econometric models being tailored to our needs and recommendations leading to tangible actions.

Grace’s passion for the science and ability to synthesise and simplify complicated modeling approaches, combined with Jane and Gurdeep’s business understanding, commercial awareness and energy ensured that the approach adopted was engaging, cost effective and results orientated; ultimately delivering against objectives.”

“The Effectiveness Partnership led Workshops not only honed our approach to measuring the effectiveness of our work, but gave us a common language across the agency group and empowered the teams to make stronger demonstrations of the commercial impact of our creativity.  The follow-up Surgeries were critical to applying theory to live client business while everything was fresh – they allowed us to very time efficiently identify opportunities and establish targets for future growth plans.  An essential course for the agency looking not just to improve the quality of their award entries, but better embed effectiveness measurement across their day-to-day work.”
“Effectiveness has always been the lifeblook of JWT. Working with Gurdeep and Janey has been invaluable in ensuring it remains so. The Immersion Day they held for the whole planning department was both inspiring and practical.

The guidance they provided was clear and concise. The case studies they drew from were relevant and extensive in breadth and depth. As I write, both Gurdeep and Janey and their team are working with our department to prepare this year’s IPA submissions.

Their contribution is proving to be of great value in all cases to JWT.”

“The Effectiveness Partnership are the real deal – experts who understand both how communication work and how to build compelling proof.

Instilling an effectiveness culture into the DNA of an agency is a mammoth, daunting task if undertaken on your own. But with the Effectiveness Partnership, you’re not on your own – they’re alongside you every step of the way, maintaining the impetus, offering sagely advice and technical help. As their name suggests, they’re money very well spent.”
