By the early 1980s, BL Systems had proved that British Leyland could build world-class technology and inspire deep loyalty from the people who worked there.
The question was whether systems alone were ever enough to save a company struggling with power, politics and purpose, as Keith Adams relates in Part Three.
The BL Systems story – the ISTEL years
If the Central Data Centre was British Leyland’s nervous system, its future was decided elsewhere.
By the early 1980s, BL Systems, later ISTEL, had become one of the most coherent and effective parts of the British Leyland empire. The technology worked. The people believed in what they were doing. External partners noticed. Yet, the wider company continued to struggle, and ultimately fail.
Understanding why means shifting focus away from machines and networks, and back towards people, power and the limits of what systems alone could achieve.
Different styles at the top
Under Derek Whitaker, who supported the early creation of a central systems function, the atmosphere was calm and rational. ‘Derek was quiet, fair and not a bully,’ John Leighfield recalled. ‘You could argue with him. He wanted to hear what you had to say.’ That openness helped BL Systems establish itself, but it came with limits. ‘He wasn’t strong enough to fight the battle that was ahead,’ Leighfield said. ‘It really needed somebody with a much clearer vision to drive things.’
That figure arrived in the form of Sir Michael Edwardes.
Edwardes came with a reputation for confrontation and an appetite for disruption. For many inside British Leyland, he was alarming. For BL Systems, he was catalytic. ‘He interviewed the top 30 of us almost immediately,’ Leighfield recalled. ‘He had our psychological assessments in front of him. The first thing he said to me was, “What should we do with systems?”’
Leighfield’s answer was blunt. ‘I told him we should run it as a company,’ he said. ‘Trade internally and externally, and succeed or fail on our own merits.’ Edwardes did not hesitate. ‘He said, “That’s what we’re going to do.”’
From that point on, BL Systems was no longer treated as a protected internal function. It was expected to stand on its own feet.
A different way of operating
Edwardes’ management style was uncompromising. Slide presentations were banned. Arguments had to be made verbally and defended robustly. When Edwardes visited the Central Data Centre, Leighfield improvised. ‘We put the slides on the corridor wall,’ he recalled. ‘So I gave him the presentation by walking him along it.’
Edwardes also acted decisively where others had stalled. ‘I remember the day he said to us, “Tomorrow we might not have a company,”’ Leighfield said. ‘That was the day he fired Derek Robinson.’ The move was controversial, but it sent a clear signal. Inertia was no longer acceptable.
Below Edwardes, relationships were more nuanced. Harold Musgrove (below), rising from apprentice roots to lead Austin Rover, was intellectually formidable but initially sceptical of systems thinking. ‘He was very bright and very honest,’ Leighfield said. ‘But he came into business too late to ever feel really comfortable with IT.’
Early meetings were confrontational. ‘He brought six of his people and lined them up behind him,’ Leighfield recalled. ‘He attacked me straight away. And then, when he’d finished with me, he started attacking his own people.’ What changed Musgrove’s view was not argument, but exposure.
A visit to ISTEL’s customer-facing operations at a Silverstone race meeting (top of page), made a huge impact. ‘He walked into our impressive customer marquee that was buzzing with excitement, and just stopped,’ Leighfield recalled. ‘There were customers everywhere. I think the scales just fell from his eyes.’ From that point on, Musgrove treated ISTEL as a serious business, even if negotiations with him remained tough.
Ownership and culture
Those negotiations culminated in a management-led employee buy-out, one of the largest of its kind in Britain. For Leighfield and Chris Chiles, inclusiveness was essential. ‘We insisted that all employees had the opportunity to participate,’ Chiles said. ‘That made a huge difference to how people felt about the business.’
That emphasis on people ran deep. BL Systems attracted highly intelligent individuals, but brilliance often came with difficulty. ‘Some of the brightest people were the hardest to manage,’ Chiles admitted. ‘The real challenge was finding the right role for them, rather than forcing them into the wrong one.’
When it worked, the results were exceptional.
Nowhere was that more evident than at the Central Data Centre itself. For Dave Handley, a Project Manager who moved from Longbridge operations into CDC project work, the place carried enormous emotional weight. ‘Everybody wanted to get there,’ he said. ‘People gave up shift allowances and took pay cuts. That’s where the future was.’
CDC was not just efficient, it was aspirational. Tours were frequent. Visitors were astonished. ‘There was nothing else like it,’ Handley recalled. ‘The scale, the seriousness of it – people couldn’t believe this was British Leyland.’
What was lost
That is why its disappearance still resonates. The demolition of the Central Data Centre and its microwave tower removed more than a building. It erased a physical reminder that British Leyland had once built something quietly extraordinary.
For Leighfield, the loss was personal. ‘One of my great regrets,’ he said, ‘is that I never took my dad to see what we’d done.’ His father had worked all his life at Pressed Steel. ‘He never really understood what I did,’ Leighfield (below) reflected. ‘I wish he’d seen that system running.’
There is no bitterness in that regret – only sadness.
Looking back, the irony is sharp. BL Systems demonstrated that British Leyland could think clearly, act decisively and operate at a world-class level when allowed to. Honda noticed. BMW noticed. The capability was real.
But systems, however elegant, cannot compensate indefinitely for failures elsewhere. Product strategy, brand confusion, political interference and chronic underinvestment overwhelmed even the best-run parts of the organisation. BL Systems showed what British Leyland could be. It could not force the rest of the company to follow.
Seen today, the achievement looks uncannily modern. Centralised computing. Distributed processing. Real-time manufacturing data. Simulation before construction. Private networks built because the public ones were inadequate.
British Leyland got there early.
It just did not get there together.

So when was the building closed and demolished?
I imagine that even if “BL” still existed, things would have moved on drastically anyway.
Yes, old data-centres from the last century, designed to house mainframe and minicomputer systems, are not really suitable for current requirements without spending a lot of money. If you are lumbered with a 40 year old data centre it will probably be cheaper to demolish it and rebuild.
I heard the DVLA are rattling around in their Swansea HQ because it was originally designed around a mainframe, which has probably long been replaced with a much smaller system.
Also they would have needed a lot of staff to computerise the logbooks of existing vehicles, something which was completed long ago.
I have great sympathy with John Leighfield over his father never getting to see what he did. My Dad also worked at Pressed Steel – he was a paint rectifier. By the time I was managing the team creating the dealer and fleet launches of new models, Dad was retired. My role was so far removed from his experience that it was incomprehensible to him. I got him in to see the Acclaim launch and introduced him to Tony Ball who chatted with him for a while but Dad still couldn’t comprehend the connection between his son and the show that he saw. It still disappoints me.
I spent 18months in Ford Purcasing and clearly remember Purchase Orders from Ford Motor Company going to bL Systems. I also recall seeing a Maestro in the Management Car Park at Warley(head Office) prior to launch in 1983
