Keith, well, I mean, the first thing I'll say is I do not believe they're mutually exclusive, but let me start first with revenue and then I'll spend some time on costs. We grew, as you know, 4.7% this quarter in constant currency. Within that construct, I would say we had very muted performance in two of our larger segments, Banking and Financial Services and indeed Healthcare, which represents 63% of the business. So one of the first things we have to do to get back to a stronger growth performance is to actually help turn those businesses around, just the law of numbers becomes meaningful.On top of that, I think we are at the stage now of investing more in growth, changing the dialogue internally, prioritizing growth. As you've seen, we have approved, at this moment in time, and I believe over time we will add to this number, over 500 revenue-generating resources or revenue support resources. So the inclination is to get back to what we've always done, which has been to focus on client centricity and revenue growth.Now cost is, of course, and strategy is important to revenue growth. First of all, what are our strategic postures, how are we exposed to faster-growing categories of the market, which are both technology categories such as digital engineering, our way of working, IoT, cloud, as well as geographic categories. And that's why I'm pleased to see the continued momentum we have in the global growth markets, which is our non-North America region.Costs, however, are important to growth because you need to have a very efficient and disciplined cost base to be able to take pricing in the deals, to be able to absorb the renewals, pricing pressure that we are seeing in our traditional business as well as being able to invest in the future. I talked in my prepared remarks around the importance of pivoting to digital and the associated parameters of that, smaller TCV contracts, more contracts, a different delivery model, et cetera.We also need to invest in people, in M&A and indeed in the brand to make sure that we are more associated not just with the area of the business where we are loved by customers but also with the pivot to digital. Many of these areas are, as you know, key to our constrained assets, both M&A targets as well as even just getting digital resources into the company.But I will say, I'm four months in at this stage. Having interrogated the data for four months and having spent a great deal of time in the transformation office, I see huge opportunity here on revenue growth and indeed on costs. I'm not going to get into a guidance discussion today around next fiscal year or indeed a multi-year view. But at this moment in time, this, from my perspective, is something that I only see opportunity in, to improve our performance from today's performance.
