How We Operate

WhichPLM is comfortable operating at all levels of your business, from C-level to the process champions, and down to the operator levels throughout the supply-chain. We support visioning, strategy and tactical requirements of the business digital journey. We operate across the entire digital value-chain from Tier 0 to Tier 4, supporting design, development, manufacturing best-practices, environmental & sustainability ‘impact use cases’ and datatypes.

Advisory Services

Fashion is being reshaped by post-pandemic changes in consumer behaviour, sourcing and logistics challenges, rapidly shrinking trend windows, and greater scrutiny and enforcement around sustainability. To respond to disruption and deliver digital transformation, brands, retailers, and manufacturers are looking to remodel their end-to-end technology ecosystems.

From trend analysis and storyboarding, through sizing, 2D and 3D pattern development, costing, sourcing, workflow collaboration, and more, WhichPLM’s strategic services are aimed at unlocking and supporting fundamental changes to the way fashion works.

Digital strategy and process benchmarking

Deeper than any off-the-shelf process evaluation, we examine process, technology, and people across more than 20 strategic areas – and sub-processes under each – to measure our clients’ digital maturity states against their their near and long-term strategic visions. Our detailed, fully-bespoke findings become handbooks for technology initiatives, cornerstones for digital transformation up and downstream, and roadmaps for creating business cases and delivering return on investment.

PLM landscaping and business case support

WhichPLM has a proven track record of working at the cutting edge of both big enterprise and agile, multi-tenant cloud PLM to make sure our clients get the best possible results from the latest PLM solutions. Based on a library of PLM solution evaluations, we examine what our clients want to achieve with PLM, which solution will be fit their needs, when they should implement, upgrade or replace, who should form the implementation team, what the budget should be, and where their PLM journey will take them.

Expert extended-PLM assessment and arbitration

We work with global brands, retailers, and manufacturers to benchmark their current PLM and extended-PLM technology ecosystems, and the processes built around them, against industry best practices. These engagements deliver an unbiased, expert perspective on how far PLM and other technologies have come towards realising their original vision, how well-integrated they are to the business’s strategic roadmap, and what future possibilities they could unlock. We also audit PLM vendors to challenge and validate their capabilities, and we can act as arbitrators to get PLM implementations back on track.

3D and DPC benchmarking and roadmap development

WhichPLM has been driving forward the adoption of 3D tools across footwear and apparel for decades. Our expert knowledge of software, hardware, file formats, digital materials, and detailed best practices extends across every process areas that digital product creation (DPC) touches – from design and development all the way downstream. We have carefully developed an evaluation framework covering problems, possibilities, processes, people and integrations – all with the goal of helping our clients to build a DPC ecosystem that’s fit for the future, and that delivers a return on investment today.
