WILLIAMSON, Nic J.

Consultant Engineer: Manufacturing. Troubleshooter & Project Manager.

Details

Services Provided:

Nic Williamson, is the principal consultant of Azteck, a partnership that delivers services in 5 areas:

Business Recovery & Reinvigoration;

Manufacturing;

Business Process Simplification;

Compliance to Regulation and Standards;

Expert Witness.

Please see headings that follow.

BUSINESS RECOVERY and REINVIGORATION

Directors may find that their business inexplicably looses its edge. We analyse and benchmark the current situation; then with senior teams, we define a strategy and business improvement plan.
Unusually, we have the project management resource to implement the new strategy and/or succession plan (if appropriate).

Analysis of current position;

Strategic Planning (including planning workshops);

Succession Planning;

Change Management;

Stimulating Culture Change;

Business Coaching;

Privately Owned Businesses;

Interim Management through the change process;

Implementation Project Management.

We bring wide experience of industry and the ‘classic’ problems.
A report might show you what to do; we will also deliver the full value through implementation.

MANUFACTURING

Our expertise runs deepest in manufacturing.

Improving Efficiency, Quality and Cost Reduction;
Automation;
Troubleshooting & Problem Solving;
Integrated Quality Systems / Health & Safety / Environmental;
Paperless Shop Floor Management Systems (Data Collection & Delivery);
Growing Pains: Technology & Business Processes;
Developing Manufacturing for New Products;
Relocation;
Project Management.

We have made significant contributions to several ‘world products’ and many clients have been ‘turned-around’ by our input.

BUSINESS PROCESS SIMPLIFICATION

We are business managers first, then, we add skills in system development. This puts the user first while developing simple user-friendly systems that deliver benefit. Software is not important (and may not be involved); it is staff efficiency and sharing of mission critical information to energise better decisions, that is.

Projects have delivered cost reductions of 1/3 of all administration costs; one paid back in 6 months by saving form printing costs alone.

Understanding the business needs;
Bringing ‘Best Practice’;
Designing for growth;
Customisation to your needs.

Our analysts learn about your business; they inject their expertise and personally create the software/system. How many companies can show that the same analyst has supported a client since 1994?

We are registered FileMaker Pro developers and members of the FileMaker Solution Alliance.

COMPLIANCE such as:
LEAN, TOTAL QUALITY and HEALTH & SAFETY

Businesses face an onslaught of Regulations, demands for Compliance, new standards & techniques such as World Class etc.

This is the last thing you need. We advise, specify and implement the steps necessary to comply ( & above all - to benefit).

Lean: Manufacture / Enterprise / Business Processes
Quality Management / Continuous Improvement;
Health & Safety;
Environmental;
Integrated (with the main business processes);
Simple and Paper-less;
Cost effective and delivering benefit beyond compliance.

4 months after a catastrophic Tesco audit, the auditor returned and commented, "Fantastic". Boots reported: "Among the best we have seen".

If you want buzz-words, we are not right for you. If you want common sense and experience, please phone or e-mail.

EXPERT WITNESS

We offer a legal-technological interface: technical investigation, preparation of briefs and presentation of evidence.
Our most valuable attribute is our ability to investigate scientific and engineering matters.

Interpreting the core dispute issues / patent claims;
Formulating an investigation;
Robust conduct of the investigation;
Plain language presentation of science and engineering.

The experts you brief will personally carry out the investigation. They personally: study the documentation; write the reports; and stand witness in court. This robust approach ensures that your brief does not suffer dilution as it passes down to technicians.

Our well-equipped laboratories and workshops specialise in investigative work.

Mechanical Engineering;
Electrical Engineering;
Manufacturing;
Product Reliability;
Failure Investigation;
Health & Safety;
Dispute Resolution;
Alleged Patent Infringements;
Forensic Investigation.

A foot note: Experience teaches us that the first subject matter considered for expert advice is inevitably not the key issue. Therefore, it is vital to engage a widely experienced expert whose speciality is the investigation and analysis process itself.
