Frequently asked questions


Advanced made simple. That is our promise to our clients. What you can expect from us:

  1. We invest in state of the art forecasting and inventory models. Ultimately the output of our planning application should be spot on, taking into account your financial and downtime risks. As an example, our dedication to service supply chains and spare parts planning led to the development of repairable control, slow mover forecasting and inventory control and multi-echelon optimization (MEO). And we want to bring more value in the future.
  2. This solution would be worthless if it was too complex for the planner. With our intuitive UI and the art of omiting we present only valuable information and planning options to the planner. Obviously more in-depth information is available on demand.
  3. Lanza is flexible from different perspectives. We can depict your business processes in Lanza with our highly flexible configuration capability. Moreover, we can easily scale your parts, sites, or user scope if required.
  4. We believe in personal service. Yes, we are a SaaS company, but we also acknowledge that the area we play in is complex. That is why we always onboard you with a dedicated team and we remain available during the lifetime of the product at your company. No tickets, only personal and responsive contact.
  5. Although Lanza is a mature and state of the art planning tool, we offer attractive pricing models. With our lean software development and deployment teams we can offer an affordable solution for any type of business.

There are a few reasons to add Lanza as an add-on to your ERP:

  1. ERP systems are originally built for production and finance. And not for repair processes and spare parts planning. Typically ERP systems lack the right forecasting methods, inventory models (especially for slow movers) and service level differentiations. These are areas where Lanza is good at.
  2. Your ERP system is a broad system divided in different modules. For spare parts planning all kinds of information should be combined to calculate the right inventory parameters. Lanza brings these different sources of information together in one place.
  3. Most probably your ERP is working with static supplier lead times. Especially in MRO environments long and unreliable lead times are the norm. Lanza takes these dynamics into account when calculating the right inventory levels.
  4. Your ERP system has - to a large extent - a tabular format. For planning purposes this is not ideal. Lanza invested in a visual user interface where planners can see trends, spot anomalies and see the actual behaviour of the parts. This increases the buy-in of planners and the outcome of the planning decisions.

We live in a world where complexity is only increasing. Businesses must deal with a vast number of assets, parts and inventory, while technology becomes more complex.

Does the following sound familiar? Your total stock value is very high, but still you have multiple stock outs every year. The number of parts that you need to manage is immense, therefore you only update the inventory parameters when an issue occurs. And probably only when the reorder point must go up. The workload in the warehouse is unmanageable, due to a lot of requests, rework and research.

With tactical spare parts management, you can grow to a proactive planning organisation that is able to prevent these kind of situations. Moreover, emotional decision taking is turned into fact-based decision taking which benefits the organisation as a whole.

Pricing for Lanza is driven by a number of things. The most important ones are scope, in terms of managed parts, but also the number of users, divided into different roles.

If you are interested in a ballpark figure we propose to have a call to look at your situation.

Key features

While Lanza runs on state of the art forecasting and inventory models we present the different inventory strategies as intuitive planning concepts. We distinguish between Wholesale, Lean, Just in Case, and No stock.

Each of these planning concepts have a set of part settings dedicated to a specific group of parts. For instance, the 'Wholesale' planning concept is often applied on cheap fast movers. Here we use smoothing forecasting techniques and an EOQ for reordering. For expensive slow movers we often use the 'Just in case' planning concept. Here the approach is more empirical and we apply a Typical Demand Quantity model. Another option is to apply a qualitative risk-based approach by means of our decision tree for slow movers.

Bottom line is that for each use case Lanza can be configured accurately by means of flexible planning concepts.

In most cases optimization means finding the right balance between parts availability (and ultimately asset availability), stock value and operational costs. And the process to manage this should be as efficient as possible.

Lanza enables the planner to apply differentiated inventory strategies to different groups of parts. Think of high availability targets for cheap fast movers and lower availability targets for expensive slow movers. In this case you achieve a decent overall availability while your stock value is often reduced.

Moreover, Lanza believes in a management by exception approach. You can set up an exception check that highlights the relevant parts that impact the business. Think of expensive parts with peak demands, or critical parts with unreliable lead times. The tric is to spend your time on these parts and maximize automation for the others.

By repeating this planing cycle you find yourself in a continuous and efficient optimisation process to improve in the triangle of availability, stock value and operational costs.

Yes. Lanza takes into account criticality information on part level. However, Lanza does not provide you with a failure mode analysis to determine these criticality levels. Please contact us if you need support on that.

Based on the different criticality levels Lanza is able to apply different strategies to these different groups of parts. Think of higher availability targets and applying minimal critical stocks that overrule the standard calculation.

Repair processes differ substantially between organisations. Lanza standardises these repair processes and enables complete visibility in the repair chain. Lanza tells you whether your parts are on stock, in repair, defect or in supply. Unlike consumable parts, repairables tend to come back to be repaired. Scrap rates, repair lead times and new buy lead times are taken into account when calculating accurate inventory parameters and performance measures.

Feel free to contact us for more in-depth information.

Supplier lead times are crucial for an accurate inventory calculation but sadly the administration is often falling behind. Lead times are often covered in the master data of your ERP, and if Procurement sets up contracts or framework agreements lead times are also taken into account.

Experience tells us that these values are often not managed well. Lanza takes these values into account while calculating optimal reorder points, but prefers to calculate average lead times from actual purchase orders. In fact, Lanza determines the reliability of this average lead time and automatically falls back on the ERP value when the reliability is insufficient. You can even configure the reliability target to your needs. This way, you are always on par with reality, certainly because this lead time is automatically updated when new POs come in.


Lanza is a standardised spare arts planning application but with lots of tailoring options. You can group your parts assortment in tailored categories, set your inventory strategies, and apply forecasting and inventory control settings. Moreover, we can apply custom rules and customized exceptions to support your planning process.

In short, if the data is available, we can use it in Lanza. Ultimately, you must be enabled in your spare parts planning but with the  right business context.

Integration & data

Lanza is a web-based parts planning and optimisation tool that makes complex supply chain and logistics planning look simple. Lanza is the ultimate add-on for your ERP/EAM system.

Typically, we build a file-based data interface between Lanza and your legacy system. Here we can integrate with any system in the market, e.g. SAP, Oracle, MS Dynamics, Maximo, Infor, Sage, etc.


We leave the data integrity of your system intact, while reading data from your system on a periodic basis. Lanza then calculates inventory parameters, such as reorder points and reorder quantities.


These inventory parameters are exported and interfaced with your legacy system on a periodic basis, often monthly. In most cases we develop an automated process to pick up the exported files and to import them into your legacy system. This is always a collaboration with your IT department. Of course, a manual integration is also possible. The same process applies for the data collection from your legacy system to Lanza.

This means that you won't be using standalone spreadsheet anymore. With this integration the planning is handled by a sound eco-system of tools.

Yes. With our smart yet simple data model Lanza integrates with any ERP and EAMS system. As subject matter experts we are used to translate business processes into the right data requirements. Once these data requirements are known we agree on a data format which we use to build our data interface.

The power of Lanza is that it optimizes your spares holding without requiring a lot of data. As a basis we need 4 data sources: master data (supplier, lead time, UOM, etc.), demand data, supply data (purchase orders and possibly repair orders) and stock data.

The solution can be enriched by pulling in more valuable data. Think of, criticality information, supersession data, or where used data. It can even be specific data that is used only by you. We bring this data in our data model where it can be used for slicing and dicing to make sure your planning is accurate for your business.

For an optimal solution Lanza requires transactional data that goes back at least 4 years. This holds for demand lines and purchase order lines. Depending on the configuration we also bring in repair order lines. 

Sometimes there is no 4 years of historical data available. For example, when a new ERP has been implemented. In those cases we either make an additional connection to the previous legacy tool or we start with using less historical data. As time progresses data is added incrementally and automatically the solution improves.


Lanza is more than a piece of software. Lanza is designed to accommodate a Plan-Do-Check-Act cycle with the goal to continuously improve your business KPIs.

  • In the Plan phase Lanza enables you to set your inventory strategies, narrow down your relevant parts by means of exception checks and intervene where needed to get your list of accurate inventory parameters.
  • In the Do phase, these inventory parameters are put back in your ERP (manually or automatically with scripts). Your operational material planners or buyers assess the purchase requisitions that are triggered and follow up on the PO's that follow.
  • In the Check phase Lanza provides a full-fletched KPI dashboard that gives you trends and bad actor lists.
  • In the Act phase you interpret the KPI results, define and take actions for improvement. Actions can be taken by changing parameters in the planning, or by changing behaviour of stakeholders, e.g. planners, engineers, buyers, etc.


The PDCA cycle is now closed.

A tool can be powerful and intuitive, but it remains a piece of software. Therefore, we offer planning as a service. Together we generate maximum impact by embedding an actionable and clear Plan-Do-Check-Act process. The role division is something we determine together.

For example, in our Comfort service we are in the driver seat and lead you in the PDCA process. In the Coach service you are in the driver seat and we will coach you where needed.

If you want to run Lanza with your own team, that is also fine. We offer an annual Planning Health Check to assess the state of Lanza and how you are using it. We give recommendations, but it is up to you how you want to process it.


Lanza is a planning tool which is used to accomodate a Plan-Do-Check-Act cycle. In 95% of the cases this cycle is 1 month.

Standard practice is that our clients use Lanza in the beginning of the month to do an exception check and to look at the KPI report.

But with the visual and comprehensive insights on part level Lanza is used daily to do analyses or to answer questions from other stakeholders, like Engineering or Procurement.

Your parts assortment is huge and diverse. Not all parts are evenly important. Therefore, we believe in management by exception. Lanza provides the relevant business rules to find and highlight the relevant parts to check, such that planners only have to spend time on what is important. These are the parts that have the most impact on your performance. By only assessing 20% of your parts, you can already improve 80% of your performance. Your people spend less time, but create more impact.
