Tour has been a rough ride - Lane
England coach Mark Lane insists the trip to the Caribbean has been worthwhile despite shock losses in both the one-day and Twenty20 series.
The double world champions - England lifted the World Cup and World Twenty20 in March and June respectively - were expected to coast past the home nation, who are well down the pecking order in world cricket.
But West Indies sprung a major surprise by beating England 2-1 in the one-dayers before taking an unassailable 2-0 lead in the Twenty20 series.
The two teams do battle for a final time on Thursday with Lane hoping to conclude the tour with a much-needed win.
"It hasn't gone the way we expected but it's been an invaluable trip," Lane told ecb.co.uk.
"The is the start of a four year plan to win the World Cup, so no-one has come out here taking these games lightly.
"It's been a real learning curve. We have probably learnt as much about the girls in these two weeks as we have in the last 18 months.
"I have been disappointed with the application and the cricket awareness of the players. Our skill levels are right up there but we have just not executed them. We will learn from our mistakes.
"We have to take away what we have learnt about the conditions, the people, the wickets, the outfield. Myself and Jack [Birkenshaw] will sit down and plan for when we return in May for the World Twenty20. We've got some good ideas but this trip has helped."
England were hindered before they left these shores as Claire Taylor and Sarah Taylor, the world's top-two ranked batters, were omitted from the squad in order to rest after a hectic year.
Rather than dwell on the loss of those two players, Lane said he would use the chance to give his middle order - who do not always get the chance to bat - an opportunity to show their worth.
"We left our two best batters behind which has exposed the middle order and given them the chance to experience the pressure of a game situation," he explained. "You can't do that in the nets.
"Lydia Greenway played two sensational innings before she got injured. She now looks like a top middle-order batsman. The captain [Charlotte Edwards] has proved again what a force she is while with the ball Katherine Brunt has impressed me too."
While England's shortcomings were all too evident in St Kitts, the venue for the group games at next year's World Twenty20, Lane was quick to praise the home side who defied all expectations.
Applauded in many quarters for their gung-ho style of cricket, West Indies have been plagued by inconsistent performances. However, Lane and Birkenshaw said prior to the tour that West Indies were a side worth keeping an eye on. Their predictions proved correct.
"I'm not going to take anything away from the West Indies," he said. "They have played some excellent cricket. We have been outplayed in almost every game.
"Deandra Dottin and Stafanie Taylor are fantastic cricketers. The whole team has been athletic and powerful. They have brought their 'A' game, we have brought our 'C' game.
"If they can play like that then there will be five good teams at the World Twenty20 in May. Sri Lanka and Pakistan are getting better too. The more good teams there are the better it is for women's cricket.
"West Indies beating us in both series has shaken a hornets' nest. There has been real interest over here. The crowds have really got into it too. It's like the West Indian passion of old."
