Enterprise Software Development: Steps, Timelines, and Cost Factors

Enterprise Software Development Guide - ScienceSoft

In software development since 1989, ScienceSoft carries out the development of modular multi-user software, which efficiently controls complex business operations.

Enterprise Software Development: The Essence

Time: The end-to-end development of the first version of enterprise software or several essential enterprise software modules usually takes around a year. The exact timelines depend on the business domain it is used in and the composition and complexity of the required modules.

Key project steps: Discovery, enterprise software planning and design, UX and UI design, development and testing, data conversion and uploadin, deployment, regulatory compliance assessment and certification procedures, iterative evolution.

Cost: generally, between $50,000 and $500,000.

Team: A project manager, a business analyst, a System Architect, a regulatory consultant, UI and UX designers,a  database developer, front-end and back-end developers, QA and DevOps engineers.

ScienceSoft helps enterprises increase efficiency and productivity with the help of secure, reliable business applications that are easy to maintain, integrate, scale, manage, and are cost-effective with a lower cloud footprint. Our team takes over end-to-end enterprise software delivery - from planning to engineering and support.

Enterprise Software Development Plan

Below are described the typical steps we at ScienceSoft take to complete enterprise application development projects.

Step 1. Discovery

Duration: 1-2 months

  • Documenting key business processes and how they’re covered with existing software, understanding the capabilities and limitations of the existing IT environment.
  • Eliciting business needs and concerns regarding the existing and desired business process flows.
  • Analyzing a broad business strategy (e.g., planned company growth and IT budgets) that can affect architectural and tech choices for planned software.
  • Drawing up high-level functional and technical requirements to software.
  • Evaluating risks of possible negative impact on business processes due to the introduction of the new system (e.g., lost productivity and downtime associated with transitioning to new digital processes, business user training).

Step 2. Enterprise software planning and design

Duration: ~ 2 months.

  • Drawing up technical requirements for the new enterprise software.
  • Deciding on the architectural style of the new enterprise software system (mostly, point-to-point/event-driven service-based or microservices) and developing its detailed design.

ScienceSoft's tip #1

Often, we see that is more cost-efficient and less risky to re-use a part of our client's legacy enterprise systems than develop and implement new software modules and enable their communication with other enterprise systems. When we decide to re-use existing legacy modules in a new enterprise software development, we add to our project plan all or several of the following activities:

  • Reverse engineering of the legacy system (including all connections and interdependencies), interfaces between software components, data structure, and data design.

Show all activities

  • Code re-factoring to simplify conditionals, remove unneeded code parts, improve code structure, review complex or memory-intensive algorithms.
  • Adding new intuitive and integrated interfaces.
  • Designing and implementing the integration of the legacy modules with new software (see more info on software integration in Note 2).


ScienceSoft's tip #2

When integration with other enterprise or third-party software is required, we add to the plan:

  • Identifying integration touchpoints.
  • Choosing integration approaches (integrating via common data storage, mediated integration of SOA/microservices via message broker/ESB or PaaS, point-to-point integration, integration via UI/RPA, etc.) and technologies (e.g., for an ESB-based integration – Talend ESB and SAP PI, for iPaaS-based integration – Azure iPaaS or Informatica iPaaS).


Non-invasive integration (integration via UI/RPA, data storage) is less flexible but also less costly and risky. Invasive integration (e.g., via implementation of SOA with re-usable functional modules that communicate via ESB) can improve enterprise agility and be cost-efficient in the long-term, but it’s expensive in the short term, architecturally risky, and may require quite deep preliminary code changes (very dangerous for legacy applications with their old, not well-documented code). At ScienceSoft, we prioritize non-invasive integration approaches when it comes to legacy software and, for more complex invasive integrations, always consider the adoption of the iterative integration approach to better control risks and prove architecture feasibility in the early iterations.

  • Enterprise application integration architecture design.
  • Planning how data should flow and whether it needs to be transformed into a different format.
  • Checking how many communication protocols between integrated applications will be used.
  • Designing additional security enhancements.
  • Preparing a comprehensive QA strategy to verify all uni- and bidirectional calls between the integrated systems, backup and recovery mechanisms, how well the integrated system works within established bandwidth limitations, etc.

Step 3. UX and UI design

Duration: 1 – 3 months.

  • UX designers and Business Analysts collaborate on UX research to understand the target audience and their needs, goals and mental models.
  • UX designers describe how a user will interact with the system (identify digital touchpoints) and design information architecture.
  • UX designers create wireframes that demonstrate basic content layout and functionality.
  • Wireframes get combined into a prototype of the application.
  • The prototype undergoes user testing.
  • Once the prototypes pass user testing, UI designers transform them into full-color graphic interface mockups that are then handed over to front-end developers.

Step 4. EAS development and testing

Duration: from ~ 6 months to several years (depends on software complexity).

  • Back-end development – to build the server side and APIs of new enterprise software. It also includes integration with required business applications.
  • Front-end development – to transform static interface images provided by UI designers into a fully functional enterprise client side and ensure its communication with the server.
  • Reviewing whether the system matches functionality, performance, security, and integration requirements. Testing usually runs in parallel with development.
  • In parallel with software development, training materials should be prepared to help users adopt the new system.

ScienceSoft's tip

Our clients often like the idea of shortening the time to release and optimizing the development budget by developing an MVP. It is a software version with only the essential features, which helps us test whether software meets the key stated user needs. Upon confirming or adjusting the initial EAS idea, we add other features to the MVP. We deliver the first working version of enterprise software of small to medium complexity in 4 – 8 months, with new functionality being added during major releases each 2-6 weeks.

Step 5. Data conversion and uploading

Duration: 3-6 weeks.

  • Inspecting the legacy data to migrate, avoiding duplicated or inconsistent data.
  • Deciding on the supported data formats and handling the required conversions if several data formats are in use.
  • Extracting, transforming and loading the legacy data.
  • Conducting ETL testing to ensure data stays complete and adequately transformed (also, where feasible, developing and running automated ETL testing, e.g., using tools as QuerySurge, Informatica DVO, ETL Validator)

Step 6. EAS deployment

Duration: 1-2 weeks.

Software gets deployed and integrated with the required corporate infrastructure. Complex software should be first moved through staging and testing environments so that the team could safely introduce changes or catch remaining mistakes before release.

Best practice

For complex projects we perform a trial implementation to minimize possible downtimes in production. The trial implementation is done for a limited number of users and requires comprehensive technical support in case any problems are encountered. Trial stages usually take up to 1-3 months.

Step 7. Regulatory compliance assessment and certification procedures

Duration: up to several months.

This stage is relevant for enterprise software or its parts falling under government or industry regulations, e.g., HIPAA, CGMP, PCI DSS. At this stage, our team compiles comprehensive documentation created during all stages – from software design to verification and validation – to prove that software and software development life cycle meet all essential requirements of a standard or a regulation.

Step 8. Further EAS evolution in iterations

Duration of releases: 1-3-6 months (depends on a development and deployment strategy).

The development and delivery of new working software modules continue iteratively according to the following scheme:

In our experience, SME can expect the costs of custom enterprise software to range anywhere from $50,000 to $200,000. For large enterprises, the cost will often vary between $200,000 and $500,000.

Major cost factors:

  • Application type (web, mobile, desktop); number of platforms and OS versions supported (for mobile).
  • Number and complexity of application features.
  • Number of business areas covered (finance, SCM, production, HR, CRM, etc.).
  • The number of business processes covered (e.g., for sales and marketing: email marketing, lead nurturing, case escalation).
  • The number of user roles.
  • The complexity of the application logic and workflows.
  • The number and complexity of integrations with custom / third-party systems.
  • Application availability, performance, security, latent capacity and scalability requirements.
  • The necessity to maintain existing data (in case of migration).
  • Frequency of the application updates and improvements.
