Change is hard work. You need the grit to change the way things are. It is even more challenging when people feel this is how things should be given the history, belief and culture. It can be insidious when culture negatively affects the group or organisation's attitude and behaviour.
When culture manifests as an unwillingness to adopt an idea or improvement, you will know things won't go well anymore. Nothing from external origins is adequate for its own good.
Most apparent of all is the not invented here syndrome. Next is the organisation's immunity system for the status quo and anything threatening people's influence and control, especially those in an influential position. The people here are not necessarily those in leadership. They can be the people that manned the cogs.
In an organisation, culture wraps around leadership, strategy, structure, processes and people. Treat it like the rubber band around the organisation. If you pulled it, it snapped back. It snapped back for many reasons.
People are programmed to do things sequentially. If you want to change the culture, transforming it piecemeal won't cut it. Changing culture itself is hard work.
Taking all the pieces together in incremental steps has proven to work. You just can't take it one block at a time. What is not transparent is the prep work behind the scene when it changes.
