David Artell told the clubs official website that the club will learn from the mistakes made last summer and continue to amend things to take the club forward.
He said: “Things are moving, and the fans will know when they are delivered. We have been talking about this for a long time, probably about this time last year and we don’t want to rush into anything we want to make sure that everything is as it should be.
“We are not an impetuous or emotional decision-making club; we have to take our time and understand. It’s not just players or staff, there’s all sorts of things to consider and it all comes back to the business model and doing the right thing for the football club.
“I think in our 135-year history, I don’t think we have ever sold as many players as we did last summer. It’s the first time in this whole club’s history that it’s happened, it’s not an excuse. It’s happened. It’s fact.
“So, we’ve got to make sure that we learn our lesson from that, and we’ve got to make sure that we’ve got the right resources in the right areas as well as the right people with the right skills in the right jobs.
“All the reviewing, processing, and understanding, is for the benefit of the football club. When you have to do all that work as well as training, looking after players and recruiting, it does take time. But we think we are near the end of that process now and we think things will be amended.
He added: “One bad summer doesn’t mean it’s a revolution, we just need evolution. It’s making sure that we’ve got the right skill sets in the right roles, doing the right jobs and I think that’s important, and all staff know that.
“We’ve had five years of success really, year on year and this is the first bump in the road. And we hope that it’s the only bump in the road.”
