Nine Things to Consider

0

eCommerce, omnichannel, speed, changing order profiles and new customer requirements, the distribution centre you designed several years ago may not be the one you need today. Over time even small changes in your operations can erode efficiency. It may be time for a retrofit to take advantage of newer technologies, process changes and systems advancements that will optimise your operation for the needs of the business today and prepare your company for future growth.

Before you start:

1. Map your processes to determine whether upstream and downstream equipment and processes are sized to handle the impact of the new equipment. In an automated environment when you change any piece of equipment, there are conveyors leading to and from the equipment that will be impacted. The speed of the conveyor has to be matched to the equipment in place.
Existing processes may require additional work stations or additional labour. Can these be accommodated in the new design? All of these can be limiting factors when considering new equipment.

2. Consider the maintenance and rehab costs of re-using older equipment. There has been a lot of merger and acquisition activity among material handling equipment suppliers over the last few years. Is the equipment still supported by the original manufacturer or the company that acquired them? What is the cost of that support? Can you still get spare parts when you need them? Equipment warranties can also be voided by changes made during a retrofit. Make sure you fully understand the warranty and support of any equipment impacted by the retrofit.

3. Dedicate time and resources to change management as part of the solution to mitigate resistance to the new processes. Process changes can be more difficult than equipment changes. New processes standards must be taught and measured.
Educating and training associates on the new processes is necessary no matter what but change management helps to lower resistance and ensure a smooth transition. Retrofits often require new operating methods and procedures. The adoption of new methods requires getting staff involved early in the process and asking for their buy-in. Prototyping is a great way for the associates to “try-out” the new design in order to gain their buy-in.
You need associates to take ownership for the change from the lowest levels of the organisation all the way up through leadership. It’s best to roll-out changes slowly through a series of meetings and training sessions to ensure that everyone is on board and ready for the change.

4. Prepare for software systems changes and the need for upgrades especially in the controls software. The systems piece can become the biggest area of cost and complexity. In facilities with a well-defined systems architecture and understanding of the functionality that falls to each system (ERP, WMS and controls software), it’s easier to add equipment and make updates to systems. This is often the case with newer buildings but over time and for any number of reasons, operations change and move away from the planned architecture.
You end up with multiple systems in a single warehouse with overlapping capabilities and no clear architecture. There’s always some level of risk around equipment controls and the handoff from one system to the next. Ask yourself: Is the I/O scheme (wiring of the equipment) to be connected together similar? Can they talk to each other?
The way to mitigate the risk is by implementing a warehouse control software solution to make the equipment work together.

5. Plan for extensive testing at production volumes because that’s where you find the issues. The testing plan is critical to success. You want to set your testing time for one when the operation is not running production but be sure to use production-like volume to properly stress test the system.
Simulation software can help with testing capabilities before you start moving equipment. A simulation will help you understand the overall flow and look at downstream impacts before you do a full volume production test. WMS testing is another critical area. Suppliers often do functional, technical and stress tests on their individual pieces of the solution, but a fully integrated operational readiness test (ORT) is necessary to ensure various components of the solution work together and that you are ready for full production.

6. Augment your existing resources. Project management is often a full-time job on complex retrofits; but even on smaller retrofit projects it can require significant time and energy. But companies rarely dedicate full-time resources to this critical role, and instead they add the responsibility for the project to a leader who already has a full-time job to do daily.
Where possible, consider off-loading some daily responsibilities from your project manager to other resources for the duration of the project so that they are able to give their full focus where it is most needed. When going from manual or low-level automation to more complex automated environments, be sure that a maintenance team is in place to support it. New software may also require additional technical resources or skill enhancements to support.

7. Budget for contingency where there are known areas of risk. What will you do if it doesn’t work the first time you turn the solution on? The timing and sequencing of changes to the building, equipment, people, processes and systems must be clearly understood and agreed upon by all parties. You may want to seek outside help to gain a better understanding of some of the risk areas (controls, certain equipment types, etc) and the long-term implications of the decisions you’ll be required to make.
Alignment of all stakeholders both within your organisation and those with whom you contract for work on the project is one of the most challenging aspects of any retrofit project.

8. Thoroughly document site conditions before you begin the design work with both structural design plans from the architect (where available) and extensive field measurements. Make sure that the slab and any existing mezzanines or platforms are sufficient to sustain the additional load requirements and ceiling joists can support the additional weight of hanging conveyor and other equipment attached to them.
Take the time to measure accurately in multiple locations. Don’t measure the distance between two columns of a platform and assume that the rest are placed uniformly throughout. If they’re not, your design can be way off or require significant re-work.

9. Choose a partner who will take responsibility for the entire solution, rather than just their piece of it. If you have multiple equipment suppliers it can be hard to find one who will step up and take responsibility for the solution when the problem lies outside their own equipment and you want a partner who will be there to support you and your team after the solution is up and running.

A partner who demonstrates they are in it for the long-term is one who has significantly invested in their controls software, provides a clear technology roadmap for development and provides 24/7/365 support for the entire solution.
