Payroll is always the central area the tool focuses on. It needs to ensure things are flowing, employees are paid on time, and there are no issues related to location, pay, or hiring. SAP HCM helps observe all the work, from hiring to paying paychecks every month. It's a system that depends on the data you input. You don't want to work with bad data and expect miracles. If the data isn't clean, it's more work.
What can be improved in SAP HCM depends on the industry it serves. The system's navigation could be simplified for users. The flow and integration between parts, like core HR, payroll, and recruiting, must be communicated properly. Users should focus on how doing things correctly from the start will improve things in the long run rather than feeling overwhelmed by tasks.
About stability, if companies think about the things I mentioned from the start, it'll be better. It's much better to have SAP help than to manipulate the data themselves. You can't put bad data in and expect the vendor to fix it. They might say it's too bad and you'll need more steps to fix it. Some organizations don't take these decisions seriously because they think vendors want to sell products. They might use one or two modules and expect others to work fine, too, depending on the correct data in the modules they already use.
I think this solution's scalability is good, but it depends on the organization. Scalability depends on what the company wants and what it's working with.
The tool's deployment depends on the type of data, where the source data is, how accurate it is, and whether there are any duplications to eliminate. This process requires data mapping and cleanup ahead of time.
The setup process usually takes about six weeks to six months, sometimes up to nine months, depending on the size of the project. It might take four months for one or two modules. However, you should plan for nine months because of potential resource constraints, budget issues, hiring consultants, and considering how many on-site resources the company has to support the project while doing their daily work.
Maintenance can be complicated. It depends on whether the company wants to do it themselves or have the vendor (like SAP) handle it. If SAP handles it, they support working with clients to ensure everything flows properly. If the company does it themselves, they might make manipulations that aren't right and make things worse. This often happens because they don't understand the delivered functionality within the system.
It all depends on how stable and standardized the company's processes are. If they make the workflow work properly, things can be easier. But if they manipulate data and expect things to work out on their own, they'll see a lot of issues. It's even more complicated when two people are doing one job, and security issues can occur.
If you do things the right way, you'll see results in six to seven months. If not, it could take a year or two, and things still won't be right.
The cost depends on the size of the organization. Compared to others, I'd say Oracle is number one, followed by Workday and SAP HCM.
I've only done one or two projects lately with SAP HCM. The use cases depend on the company, what it's implementing, and what issues it deals with daily. They also vary based on the modules it's working with. There's no generic situation.
How SAP HCM supports an organization's HR needs depends on where they want to go with the information, how they want to grow, and their budget requirements. I usually use a specific version within the core HR space. The impact depends on the project and the organization's size. The impact isn't big for small companies with few employees because they can use the standard functionality. However, the impact is huge for organizations with over 5,000 employees.
People often worry about the learning curve when switching from a system they're used to. They get curious about how much improvement they'll see rather than focusing on learning and seeing the results.
You need to be prepared to use the solution. You don't need to be a professional, but you shouldn't overthink it or worry that you won't be able to do it just because it's new. Many people get carried away in that process and lose track.
People often hesitate to learn and worry about different tasks. Instead of going from A to Z, they look for shortcuts, which don't work in all environments. You must go through the learning process to understand the system properly and get the necessary information. People often look for shortcuts, which isn't the right way.
I rate the overall solution a seven out of ten.
